I just picked up one of these for an unbelievable price. I'm glad I ran across your video. Was going to flip it but now, I think I'll keep it. 479 hours built in 81. In 91 had sound suppression kit installed. Have record of everywhere it's been. Good video
If it had a sound suppression kit installed its not an MEP-80x its an MEP-00x 5kw is MEP-002 and 10kw is MEP-003 This video is of the newer water cooled units. Yours is an air cooled unit. Air cooled units are quit a bit louder and not as sought after but still very good machines. I have a few videos of a MEP-002's that I had too.

@@electromechanicalstuff2602 I also have a old school 10kw that was upgraded to a 12kw. When I say old school I mean it has the hecules flathead four cylinder in it. Built in the 60's. Runs like a top but drinks the gas like a fish drinks water. It only has like a 1000 hours on it. I'd have to go look at all the numbers to tell you what it is exactly. I've owned it for a few years. I actually bought the mep002 because of the diesel engine thinking I could swap the engines. But it turns out the mep002 is in really good shape so now I don't want to do that even if it would work. Also looking things over I'm pretty sure the engines wouldn't interchange anyway. So if the mep002 will run my house with no problem I may just put in in instead of the 12kw. I just to have plenty of extra if I have the option you know.
@@electromechanicalstuff2602 I paid 250 bucks for the mep002. Just one of those things I couldn't pass up regardless of whatever I had in mine to do with it. 600 for the 12 kw. At an auction, people were scared it was a 3 phase. They didn't realize it was both
@@aaronwood3540 the 002a is only 5kw capable of about 8kw. The gen head in these units will produce way cleaner power then that old hurcules. Youd be downgrading it if u put the diesel on a less quality gen head
I was buying them two at a time in hopes I could get at least one running. got both going put both up for sale first one to sell and I keep the other. buyers called for both. so I sold both. bought two more same concept got one lemon with a sized engine kept the one parted the other out.
I figure that tiny bump/ripple in sign wave on up and down would be it firing, being a 4 stroke 2 cylinder you should see 2 bumps like what was shown. Very neat to see that.
Got one of these.. MEP-802A awesome generator.. One thing that is stated on one of the tags is "EMP Proof"!! Not one piece of electronics on this puppy, no ignition, Relay logic!! Most all military is Diesel for common fuel, no ignition, EMP resistance. I tested mine at 7KW, not recommended, but took it without Any complaints. Surge capacity is greatly underrated. Military Grade! Found mine for $2K w/200 hours and fully serviced from a guy in Pennsylvania who was flipping surplus Military generators. There are commercial diesel generators, some run at 3600 RPM which IMO defeats the reason for going diesel where 1800 is much closer to diesel max torque/efficiency. Sound deadening in the rain proof enclosure is darned good. Standard Service items (filters mostly) are available commercially. My goal is to use this generator for intermittent battery charging in an inverter system. Solar power isn't that reliable here in Maryland with often overcast skies. Running a generator with a light load is where fuel efficiency is lost. My full use electrical requirement is about 1 MWH per month which equates to an average load of ~1.4KW. Running this generator at about 25% duty cycle w/a battery sourced split phase inverter system capable of ~12KW peak will reasonably run everything I have without any concern. The default power source should always be Grid power which is currently by far the cheapest power source.
I would target 50% load cause like u said fuel efficiency is lost on light loads. That generator will burn close to the same amount of fuel weather it's 25% load or 45% load. Secondly and most important these gens are kind of sensitive to wet stacking. If u only run low load most times at least once a month u need to run 100% for an hour minimum to make sure you burn off any unused fuel/carbon in the engine. If u ever see wetness anywhere on the exhaust put 100% load on right away or u risk washing out the cylinders. Lots of surplus generators are in the auction because of this reason. Many many are just fine. I've had over 20 units and only one was bad and that's cause the exhaust flap was left open and the engine had water in it. I now have a 803 and I plan on doing something very similar use generator during day for house loads and charge lithium batteries especially in winter when only the furnace is running at night then at night run on the lithium batteries. This way too during the day the generator will have a good heavy fuel efficient load.
@@electromechanicalstuff2602 Nice info.. thanks.. you must be another MEP Flipper? The guy I bought mine from bought them by the Lot, pennies on the dollar from Gov't auctions. With most inverters you can select the generator Start/Stop battery voltages.. and Max charging current so your 50% load recommendation should be easy to set up.
@@markhall3434 exactly. I set up my buddies solar system in hawaii the same way. U can get auto start units for these too from greenmountaingenerators.com Ya I flipped em for the first few yrs they came out. The auction prices in the north east of the country got too high for profit So i got out
@@markhall3434 Auto start. So basically your inverter has an output to request generator startup and will have priority that if there is grid power to use that to charge and passthrough power to load. U can set soc for that command like for lead acid I'd do 70%-80% lithium would be 20%-70% greenmountaingenerators.com/product/mep-automatic-transfer-switch-controller-for-most-mep-military-generators/
wow i'm amazed of the amount of features of the military generators(and the cleanliness of the power through the oscilloscope) , i thought that they were designed just to power aircrafts(that uses 400hz) but from your video i have learned that,military genset is 1000 times superior than comercial,with that... i just have to congratulate you for your initiative to upload something like that, I´m strongly encouraging you in the name of the whole community to tell us more about them(servicing wiring diagrams, servicing components and other devices not seen on comercial gensets),i have to ask do they have synchronizer for automatic paralleling with other machines? we'll tracking you continuously..........great job!!!! .
I have thought of making videos like that. I will in the future. Some units are 400hz the 60hz units are mep-802, 803, 804, 805, series. The 5kw and 10 kw do not have auto synchronous feature. But the military does sell a kit which is basically just a bulb to Identify when to energize the output contactor. The 15kw 804 and up do have the auto synchronous feature. I have a video on the 804 unit and u can see the switch for it. I'll find a video on how to synchronize them
look up ch-1 generator interlock switch kit from national RAM electronic. it works off the same principal. keep the main breaker from being in the on position while the generator breaker is on and vice versa
What makes these military diesels last longer than the cheaper one you showed is the fact that the engine it runs at 1800 RPM vs 3600 RPM of the smaller one. They make 3600 RPM diesels also and those will last a little longer than the gas versions but not alot more. The bearings and all moving parts of the higher speed engines wear out at a MUCH faster rate logarithmically.
The speed is a huge factor, that is correct but also look at the robust components of a diesel vs a gaser. The piston rods are twice as heavy, the blocks are twice as thuck, the metalergy in general is usually of a higher standard to handle the higher compression ratios, cylider pressures and torque.
On the cheap one the scope was connected between line and the chassis. On the good one it was connected between line and neutral. Depending on the internal wiring this might not matter.
I usually went for newer units but the most important thing to me was to make sure it was not a rebuilt unit. There is a small tag by the data tag that indicates an overhaul.
Unfortunately I don't. It is one of the gauges that fails the most because of its sensitivity. Mine is a bit sticky right now too. I parted out a whole mep-803 and that was the first part I sold
How does it do with the inrush starting on the HVAC unit? We are going to build an all gas home (cook top, water heater, furnace backup) and will need one to just run HVAC/refrigerators like you're doing. I sold my MEP-003 and I'm torn between the 802a and the bigger 803a.
It does real good on my 3 ton 13 seer bryant AC unit. The only thing is you dont want much more then 2000 ish watts currently being used when it starts to keep the engine from boging down. So the days you know you'll be using it keep the toaster oven and every ceiling fan in the house on at the same time to a minimum. Myself to combat this i found a load manager from xantrax. Its called xantrex freedom sequence power manager. All your power runs through this first on its way to your panel. U can add some 15-20 amp 120v loads to it for shedding or what im going to do is utilize the built in low voltage relays to interupt the AC contactor signal wires. (The little wire going from your furnace to the outside AC unit). This way it will determin if theres too much load currently being used it wont start the AC unit or if the unit is on and someone starts the toaster oven and microwave and all the fridges kick on it will shit the unit off untill the generator can handle it again. All the treshoulds are programable and there's a few vids on CZcams about it. Even big natural gas whole house generators use this technique in the automatic transfer switch. I haven't done it yet but ill be going at it this summer.
Excellent information! Thank you so much for sharing. I didn't know the Xantrac device existed. Now to make my decision and this definitely makes it easier. Thank you!
I was looking for someone that's prepper minded willing to join a small crew of like minded people that has credible knowledge in a certain field. I have hunters planners builders mechanics etc. And we grow catch and cook our own food but no one in the electronics division. We don't prep for anything in particular. Just be set up and ready for whatever might come our way. Basically just a handful of good loyal friends willing to put in a little effort to have a place to go if the shit hits the fan in whatever way that may happen.
Who said I'm prepper minded? Where are u located? "handful of good loyal friends" There not all strangers like me from CZcams are they lol? I get it nothing wrong with being ready for a snow storm or Hillary haha. but i wouldn't be willing to join a group of strangers and feel like your loyal friends to me and trust random ppl with my life. just saying thanks for the invite tho.
@@electromechanicalstuff2602 everyone is strangers until they get to know each other lol. But yeah I wasn't suggesting jump in your truck and head this way lol.
FreemonSandlewould yes thats exactly what its designed for. You will only have to shut it off every 500 hours to change the oil. So every 21 days. You can hook up an aux fuel tank of any size and the on board fuel tank has a second float that with refill the onboard tank to 3/4 when it gets below half tank automatically with the built in aux fuel pump. Just turn the main ignition switch straight up and down to prime & run aux fuel position
Uhm, no. I'm a 91D20 :-) Hello from Korea. Check LO 9-6115-641-12. 250 hours or 6 months to the service. Use cheap ole 15w-40. I normally see about 4000 hours out of an engine before I have to swap them, and swapping an engine is a pain in the ass. Also note that life really sucks when someone does an AUX fuel but the fuel level sensor is broken, and it pumps the whole barrel onto the ground overnight.
how did you obtain this unit? was it at a government liquidation sale? were you allowed to inspect the unit before placing a bid? how much was the purchase price? thank you for your time and look forward to a reply. I am in the market for a standby generator and looking for information on the subject of military surplus.
thomas marabillas yes govliquidation.com does allow squeduled previews but tge closest site to me is 3hrs away. I dont know if govplanet.com will allow previews. Look for reset tags the tan one have tgem more often. Dont buy it if it has that. Look for wet stacking around the exhaust manifold. They can still run but usually never at tge rated power tgey once could without a rebuild and they'll burn oil if they're westacked. I lile going for ones that have the exhaust flap in pristine condition to better ur odd rain water never filled the engine. U can get them depending on availability in your area and how many per auction and how many hours 1500 or less is a number i go for. They can very from $1000 to $2500 for a good one.
ebay just seen a fully restored MEP-003a selling for 5k but this guy is comparing apples to oranges. 1 cylinder vs 2 cylinder, portable vs not portable, not to mention totally two different types of generators....
Syc holic fully restored? By who? Some guy or the government. Like i said above if its been restored by anyone and has a "tier 2 reset tag on it" it's got a ton of hours on it with a few new parts to make it run and a new paint job. Yes i am comparing aples to oranges. Which is a good mil spec gen vs an average home owner style gen. They are very different. My point is those $1,500 or less consumer generators have "dirty power ". Everyone and there mother has heard that term before on gens. Now u know why people say that. If you are using a gen for your home backup just be aware that using "dirty power" is very bad for your electronic devices and it will shorten the usable lifespan of your devices.
you arent paying for clean power, they are designed for motors that dont care about dirty power like power tools.. just saying ya comparing apples and oranges. btw this was the one I seen. looks pretty mint to me. (ableit I wouldnt go purely on 'looks') www.ebay.com/itm/MEP-003A-MILITARY-MEP-DIESEL-GENERATOR-10KW-ONAN-803-802-002-MINT-REDONE-ARMY-/122912929883 I would also go out on a limb saying that coleman is a total joke, 100% duty cycle with a power factor of 1? lmao BULLSHIT... Also dont get me wrong Im not saying your gen isnt way better but that coleman is like a harbor freight special.... really isnt comparing the two. should pull the cover off the coleman see what kind of field flashing it does and is there a AVR etc also what does the sine wave look like under a load? should even be a warning on that manual saying dont use 'electronic devices' with said generator again just by looking at it screams to me power tools only...
Syc holic holy crap 5500 for a early 80s air cooled 003a with a new paint job. Those things didnt come with digital gauges either. Have you ever heard a 002 or 003 run? They are louder then that Coleman. They put out clean power too but man are thet loud. I usually get the 002 and 003 from auction for under $800 ive had 3 or 4 of them over the years. I give those ones to family memebers who live in areas with no neighbors. I've been trying to get ahold of a honda diesel 6kw so i can scope it and try to start a 3 ton ac with it.
I have an MEP-003A which is 10kw and air cooled. Bought this a backup to my Generac 20kw propane / natural gas primary unit. The Generac has an automatic transfer switch and will run my entire house including 2 central air units - 5 tons each. It will auto start and has circuits wired into house thermostats so it will start only one AC unit at a time. Runs the whole house with no problem. Bought the MEP in case of extended outages. Wouldn’t want to run the Generac more than 12 hours or so. The MEP will run for days at a time and will run the whole house with just one of the 5 ton AC’s running.
Doctor Goop ive run 3 3tons with a mep-803 also a 10kw but u would definatly see the lights dim for a sec especially if that start at the same time. Thats one thing generac buyers usually dont know too. Is there $10k units cant run more then a few daya without needing service. Hope u werent one of the people who figured it out after u bought it
This is old video but have a question hoping you have the time to answer. My 2004 Motorhome has an Onan gold marquis 5500 on it. The hours are getting up there and at the moment in having to live in it while I build my shop and home. Have the opportunity to buy two of these with low hours and excellent working condition. Can I run my 50 amp motorhome off of one? The most amps I have ever seen pulled with both AC units running and all lights and electronics on is 27 amps.
I really appreciate you answering. I got it set up but I'm not gett8ng ant power to my motorhome. I've tested with shore power and rv side is all good. Plug into generator cord wired exactly how you have it but have no power from gen. Have 110 from the generator sockets and all gouges show its working but I don't have power. 220 V on meter but nothing. Is there anything else I'm not turning on to get power? Does the ac interruptor have to be on?
Mep-802 is 5kw rated 6kw actual Mep-893 is 10kw rated 12kw actual. Rated at high altitude to perform. So at sea level u get a but more plus 300% starting surge
Hello I’m looking at one now 2009 Mep 802a with 125 hours no resets. It looks good on outside. I see some whitish staining on hoses like it was dripping on insides. He asking $3500.
I'd really appreciate it. I have very similar model as a spare to a generac(chinese somewhat okay not really genset). I heard you just have to be really careful with loading and unloading to avoid spikes and dips and they clean up a lot with some resistive load on them.
Oh something that may be easy for you there. Can we get a quick vid of that sine wave unloaded? It might even be cleaner. Electric motors spit out straight garbage into the system.
As a licensed refrigeration technician who works on 500 ton units and smaller. That coil is not that bad at all. I wash em off several times a year. That r410 unit was 2 or 3 years old at the time of this video and it is now 10+ years old and still running strong. I've since sold that house made $150k on the flip to a Friend. now living on some property in the country that has two r22 units that are about 16 years old and run great also and i have two brand new 30lb bottles of r22 i got for free 5 years ago. I'm not worried at all. Plus don't write everything in capitals. It means you're yelling.
Used to be govliquidation.com online auctions. They had a contract to buy surplus. Now I think govplanet.com is the only one around. But auction prices have shot through the roof from people bidding on stuff they did not know anything about cause they heard a guy got few good units once soon a time. Many of the units have serious issues. Most of which a trained eye could spot. But people where bidding top dollar on units that where clearly only good for parts. I used to get a good 1,000 hour unit for $1500 and a parts unit for under $500 last time I checked they where selling for $4500 for any unit. I'd drive out of state up to 13 hrs away to pick up 4-5 units at a time and fix em up and sell em for $5,000-$6000 each.
In Germany we have these nice Stasi bunker 19 KVA Diesel generators from eastern germany, its also very solid and reliable, restored it a couple of years ago : czcams.com/video/U7vFHo2l1gY/video.html
PgPgDn they are 12 wire gen heads they have a reconfigiration switch on them behinf the gauge panel that allows for full power output in 3 different configurations. 120v single phase. 120/240 split single phase or 120/208 3 phase. I keep it on 120/240 spit single phase. Only the mep-002a 5kw, mep-003a 10kw, mep-802a 5kw, mep-803a 10kw units have this ability. The 15kw units and up are 3 phase only. However sewrzuk has a video showing how u can rewire the mep-004a to 120/240 low zig zag with some easy mods to the reconnection board but the newer mep-804a are only 10 wire gen heads and cannot be reconfigured for single phase
@@twofortyrida JP8 is a much thinner fuel. Also these engines should be around 1:16 compression ratio, while a commercial engine will be 1:21 or so. The upside is the military fuel and low compression ratio, combined with glow plugs, these will start no problem below zero.
I would like to see you compare the sine wave of a good inverter generator (like a Honda or Yamaha). They are designed for consumer electronics. That Coleman hog is not.
Jake Logan your right. But that hog is what most people have amd is what most people backfeeed their homes with. My friend just got a champion 3000w inverter gen im going to scope soon
Jake Logan czcams.com/video/bXsTfUOllJM/video.html czcams.com/video/XChmkKRVDUA/video.html Id so like to see any inverter generator start a 3 ton ac unit or 3 of them czcams.com/video/nJz45Hn6vgE/video.html
Good videos. I have two portable inverter generators myself, and three portable conventional generators. Looking to get a MEP-802A soon. Oh, and last night I was running 10 aeroderivative generators and putting out a total of 900+ MW of power. No joke.
Jake Logan I'M a non practicing A&P mechanic. I've started up commercial airplanes too. Only about 90MW. The real money is in R&D automotive tho. So you either started 10 planes or ran Fermi 2 at about 75%. Lol
TIM Williams watts are watts. But they are dirty watts clearly from this video you can see that. Using a suicide cord into your dryer plug is going to get someone killed and you put in prison for negligent man slaughter. Even if you do everything in right order. Good luck proving to the power company and the sherrif standing next to them that it wasnt you who killed the lineman down the road. It could have been the guy down the road who actually forgot to shut off his main breaker but. How can u prove it. Dont use a suicide cord. Its called that for a reason. Use a breaker panel interlock or a transfer switch. Someones life is worth more then the few hundred bucks it'll cost u
Mark B price is extremely variable. Depends on state the auction is in, How many are in the auction, how many hours on unit, wheather its a tier 2 rebuild or not, weather its running condition unknown or been tested, how many hours on unit, visual condition, has visable wetstacking on exhaust manifold or not, has good condition exhaust flapper or not, on a trailer or not. I usually go for around 1500 hours or less, no tier 2 reset tags, good visual condituon, no visable wetstacking, running condition unknown, good exhaust flap, with or without trailers, but newer Humvee style tires if i get a trailer. And anywhere from $1000-$2500 I'll spend and ive spend $2500 on ones with locked up motors on trailers
Still a huge bargain it seems. They would be using quality american made engines and components? In australia we would be paying 4-5k for chinese junk with similar outputs and higher end stuff can easily set you back 10k. Maybe I need to buy a heap and bring them back to aust.
I usually try to buy under 1500 hours. Oil change intervals are every 500 hours. Just look for wet stacking. Tar/ oily residue around exhaust manifold. Its from running without enouph load. 30% min load at all times.
Also look for a tier 2 tag by data plate that has year on it. Means its been oberhauled by the military but the clock gets reset. Usually they have had alot of hours on them to require an overhaul
@@richardi1124 id go with bad but can be ok. Teir 2 reset means its been ovethauled. They dont replace everything. Just do the updates that are required and fix anything broken. Usually they only get teir 2 resets after a major breakdown. Like motor or gen head. They reset the hour clock. So u dont know how much time is actually on the unit. Alot of parts may still have 5,000 + hours on them. Its hard to say exactly how long it will last. They do go thrugh it and make it right but not as good as a non reset unit with less the 2,000 hrs if u ask me. Thats only my opinion. People may have diff opinions. Ive seen 8,000 hr units run fine. Ive seen units with 300 hrs on them destroyed because the operator let it wet stack. So it really depends. Wetstack is the biggest concern
I've seen huge piles of these thrown away in Saudi Arabia by the military. I was told it's cheaper to scrap them.than send them back state side. Go figure
Rayford Hickman if they dont spend the budget they wont get as much next year. Literally a donzen of the units ive gotton over the years where sabotaged when i got em. Usually oil pressure wire cut or something easy like that to cause it to not run and shut down via saftey fault codes. Its obvious they need new gens cus the others are "no good" the other 50% off all the units in the markets are usually junk cause of wet stack or watter got in the exhause and locked it up. The other half simple or no repairs
Bypass the safety shut downs. Over temp, low fuel level l, low oil pressure, over or under voltage etc. Genny gets hit by shrapnel it's more important to keep up comms and medical equipment than worry if the motor will be damaged
@@curmudgeinnak they are cool. When they first hit auction I was getting them for like $1200 with less than 1,000 hrs. But then everyone and their mother started bidding on them and driving the price for parts units that had missing parts past $4k not knowing what they were buying. Main thing to look for is the exhaust. If it has black oil or tar like substance on it the motor has wet stacked. Sometimes u can fix it with just 100% load for 8 hrs sometimes u can't. U must maintain 25-30% minimum load on it at all times to prevent wet stack. Otherwise the engine won't get hot enough to burn the diesel completely coats the cylinder walls and allows oil blow-by that just gums up everything. So when buying and not sure wether u want a 803/10kw or the 802/5kw know that u have that minimum load requirement 1500 watts vs 3,000 watts continuous load can be as simple as a one or two space heaters. Mine only runs to charge my battery bank so that keeps my 10 kw unit at about 80% load for about 6 hrs
@@electromechanicalstuff2602 the 5kw would get run to charge my lithium at between 50 to 100 amps going into the batteries. Been using a crappy Cummins gas generator and it is horrid on gas. My yanmar is down and needs to be rebuilt. It is a old L90
Govplanet.com I think but your paying top dollar these days. Ebay sellers too. Mep-802 = 5kw Mep-803=10kw both can put out 20% more then rating. Don't buy it if it doesn't run. Stay away from units missing exhaust flap and over 2000 hrs. Most units are in georgia right now.
No it's not. The 802a is a 2 cylinder 5kw and the 803a is a 4 cylinder 10kw I have bought , repaired and sold 20+ of them. Now semantics. The 5kw unit can actually put out closer to 7kw and the 10kw unit can put out 14kw
Check out my latest videos. Lots of politics but in there is also solar videos. I didn't find $37 dollar panels but I did find $130 375watt used panels so in stalled 16 of them. Before that I installed 16 390 watt new panels at $300 a panel. When it comes to back up power one is none and two is one. Now that I have diesel and solar I sold my little 5kw yanmar diesel
You know sadly this video eloquently demonstrates the difference in product quality. Granted a new civilian version of the Mep-802 is probably ten grand or more. What's sad is the guy who will spend hard earned money on the POS.
w4csc i dont have a honda. So take a Video of it on a scope and put it in the description. Have fun changing ur oil every 50 hrs. Theses only need oil changes every 500 hrs. Id love to see that honda start up a 3 ton air cinditioner. There different yes but at .3 gal/hr not a fuel hog
There is a 7000is(4 grand) that started a 4 ton. It wouldn't shock me if he turned off everything he could if it started the 2 ton as well. I've heard of these units putting out way more then rated. They are freaking pricey though. czcams.com/video/a2ASAWGwrjc/video.html It'd be butter with a softstart kit(300 a pop just depends on your needs). Check out the new Westinghouse wpro8500 5% THD. I think even an inverter generator is typically in the 2-3% range and looking at that oscope just guessing it looks somewhere around what a 5% wave looks like too. 5% is supposedly some magic number. 9% works but is not ideal. Looks like the best consumer grade genset to come out in awhile. Looks like it's coming out of the same china house as generac. Not that that's awesome but generac seems to be at the top of the Chinese heaps along with champion. Nothing like this unit you have and I'm sure it'll bog down at the 11k surge. However it seems like the best your gonna get for around a 1100 new in box with a 3 year parts warranty from a big box store. Burns about half a gallon an hour at half load.
Bought mine for 250 bucks. 5000 kw, 479 hours and have a record of everywhere it's been. Not exactly what I would call spending a ton of money on a pos
@@JONNYGEEKMANG No doubt that Honda is an excellent unit. I would be interested in seeing what the voltage drop is on that thing during start up. When that MEP starts my AC I barely see the lights flicker any more then when I'm on grid. The 5-2-1 hard start kits are great I have them installed on every unit right from the get. Had a brand new Bryant installed 2 years ago I installed a 5-2-1 as soon as the van left my driveway. I was getting these things from auction running condition unknown for $900-$1500 and selling them for 5k I only had one bad unit ever after years of buying as many as I could every time there was an auction. but knowledge on what to look for helped my odds a bit better then buying any random unit.
I know about those "screamer"generators Techunseh piss poor engine and the chineese generators worse throw away crap !!! . I have a MEP 004 AAS unit . for our military comapnies never cheated on quality
.Hallo Chuck, ... the chineses did learn bloody - but as I*ve seen on market -alibaba, recognized - as newerly are eqipped with (if required) US-MFr. Kohler and-/-or Briggs+Stratton, now - also experienced: I am looking next Auctions for quality, so GovPlanet (former IronPlanet) for 5Kw- MEP-802A GenSet or 15-KW-MEP-804A most offered years 1993 /-95 w/hours +- 300h. - the prices In Germany, ex-stock-US-Depot Kaiserslautern are Euro= .600/ -800 with best wishes, and best Greetings from Germany... God bless America..
Yes, yes --- but you're comparing apples to oranges. The diesel generator cost the taxpayers probably 25 times what that PowerMate costs and weighs 4x as much. You can forget about taking it camping for a weekend. But is it a better generator? Absolutely.
More like oranges to mandarins. Most ppl use generators for home backup. I evwn said the coleman was only good gor job site stuff. But home backup as the main use i wouldnt use one of those type of gas gens unless its an inverter style wuth pure sinewave
$3500 from me. current cl add detroit.craigslist.org/wyn/tls/5245633270.html or you can get ones from greenmountaingenerators.com/product-tag/mep802a-generators-and-parts/or places like that who have also done load testing but there more like $5000 there
Actually, the horrible waveform of the garbage genset makes no differenceto any electronics manufactured since 1990. Every device uses a switching regulated DC power supply rated for ANY voltage from 80 to 300 volts at any frequency. The input you feed it is immediately rectified and charges a big capacitor to some dc voltage. The switcher's pulse width at a higher frequency varies to regulate the dc output voltage. It could care less what the genset waveform is,
K.... Dirty power is fake..... Inverter generators are just a money grab...... Or the low voltage power supplies are infact what fails when you run dirty energy. U can literally hear the power supplies whine when on dirty power. Ever actually own a radio or analog TV. Turn on a vacuum in the other room. What happens to your signal... Dirty power transient spikes ......
@@electromechanicalstuff2602 My diesel stepvan is powered by a Honda EU3000is electronic generator I got cheap. Its output looks great as Honda's sampling rate is higher. The BEST feature is ECO mode. Loaded at 1600 watts, eco on, the engine is only turning about 1500 rpm as output frequency has nothing to do with engine rpm. It's very quiet.
@@LarryButler-kp3se this diesel mep unit only ever runs at 1800 and it's always quite. Plus oil change intervals are 500 hrs. I can connect infinite size aux fuel tank and don't have to worry about the engine needing any real PM for 8,000+ hrs
@@electromechanicalstuff2602 Sitting in my yard is a 41-year-old Mercedes 300TD with around 900K on it. (it wore out odometers) It gets Rotella T4 dino oil every 3000 miles and consumes 1/4 cup between changes. It starts instantly glow plugged at 5F. 500 hours is too long for diesels as they contaminate the oil with unburned fuel and soot. ALL diesels have ring blowby. Large diesels, like ship diesels, have extensive lube oil filtration systems because of this fact.
@@LarryButler-kp3se just what the manual says. I've seen this units at auction with over 9,000 hrs on them and I know the government isn't going to do more oil changes then recommended
Quality. Those NG/LP air cooled motors won't last 1/2 as long. They need oil changes over 200hrs this one is 500 hrs. At 400 hrs the NG Needs valve lashing this doesn't for 5000 hrs. NG 10kw has no surge rating. So don't expect to start a 3 ton ac unit with it. This has 300% starting surge. The NG is just an air cooled lawn mower engine this is an onan diesel made for industrial equipment. The NG is a slip ring exciter that adds distortion this is brushless exciter with grid quality sine wave. Because it's water cooled its way quieter. This service must be done by a certified generac tech to retain your warranty. I've seen these military units with 8,000 hours on them regularly. I have a friend who used to service the whole house units and the valve seats usually only last 2000 hrs and then the head needs to be changed. www.generac.com/service-support/faqs/maintenance-kit-faqs/what-maintenance-do-i-need-to-do-and-how-often
Plus this is portable as long as u have a machine to move it. Mines on a trailer. It also has the capability of 3 phase output. I installed an automatic transfer switch and control board for automatic start in the generator. But if your not capable and just want something u can call a technician out for repairs I even recommend the whole house units because not many people know how to work on these military units.
I paid a hospital clinic $500 for my 33KVA diesel genset, including the hot start switchgear. It's Cummins engine had 220 hours on it. I paid $1200 to ship here. Long cables feed power to my neighbors who fund the underground 250 gallon fuel supply and maintence. We're out of power about 30 seconds.
Other then I said commutator instead of slip rings . What else did I say that was BS? Diesel doesn't varnish like gas and does have a longer shelf life. As long as you keep water out of diesel it stays good a very long time. The THD on the Coleman can and will damage your sensitive electronics. Brushless generators are typically less noisy because of there very nature. There are more reasons for the better THD I can explain them better now if you'd like to know about them.
im jealous of your military generator, that one is pretty damn clean!
same I just got a used Chinese 6kw generator lol
They are some beautiful machines !
I just picked up one of these for an unbelievable price. I'm glad I ran across your video. Was going to flip it but now, I think I'll keep it. 479 hours built in 81. In 91 had sound suppression kit installed. Have record of everywhere it's been. Good video
If it had a sound suppression kit installed its not an MEP-80x its an MEP-00x 5kw is MEP-002 and 10kw is MEP-003
This video is of the newer water cooled units.
Yours is an air cooled unit.
Air cooled units are quit a bit louder and not as sought after but still very good machines.
I have a few videos of a MEP-002's that I had too.

@@electromechanicalstuff2602 I also have a old school 10kw that was upgraded to a 12kw. When I say old school I mean it has the hecules flathead four cylinder in it. Built in the 60's. Runs like a top but drinks the gas like a fish drinks water. It only has like a 1000 hours on it. I'd have to go look at all the numbers to tell you what it is exactly. I've owned it for a few years. I actually bought the mep002 because of the diesel engine thinking I could swap the engines. But it turns out the mep002 is in really good shape so now I don't want to do that even if it would work. Also looking things over I'm pretty sure the engines wouldn't interchange anyway. So if the mep002 will run my house with no problem I may just put in in instead of the 12kw. I just to have plenty of extra if I have the option you know.
@@electromechanicalstuff2602 I paid 250 bucks for the mep002. Just one of those things I couldn't pass up regardless of whatever I had in mine to do with it. 600 for the 12 kw. At an auction, people were scared it was a 3 phase. They didn't realize it was both
@@aaronwood3540 the 002a is only 5kw capable of about 8kw. The gen head in these units will produce way cleaner power then that old hurcules. Youd be downgrading it if u put the diesel on a less quality gen head
Did you realize it was both? a lot of people are turned off by that not knowing. @@aaronwood3540
very nice comparison between the two.
I was buying them two at a time in hopes I could get at least one running. got both going put both up for sale first one to sell and I keep the other. buyers called for both. so I sold both. bought two more same concept got one lemon with a sized engine kept the one parted the other out.
That is one sexy instrument panel!
I figure that tiny bump/ripple in sign wave on up and down would be it firing, being a 4 stroke 2 cylinder you should see 2 bumps like what was shown. Very neat to see that.
Got one of these.. MEP-802A awesome generator.. One thing that is stated on one of the tags is "EMP Proof"!! Not one piece of electronics on this puppy, no ignition, Relay logic!! Most all military is Diesel for common fuel, no ignition, EMP resistance. I tested mine at 7KW, not recommended, but took it without Any complaints. Surge capacity is greatly underrated. Military Grade! Found mine for $2K w/200 hours and fully serviced from a guy in Pennsylvania who was flipping surplus Military generators. There are commercial diesel generators, some run at 3600 RPM which IMO defeats the reason for going diesel where 1800 is much closer to diesel max torque/efficiency. Sound deadening in the rain proof enclosure is darned good. Standard Service items (filters mostly) are available commercially.
My goal is to use this generator for intermittent battery charging in an inverter system. Solar power isn't that reliable here in Maryland with often overcast skies. Running a generator with a light load is where fuel efficiency is lost. My full use electrical requirement is about 1 MWH per month which equates to an average load of ~1.4KW. Running this generator at about 25% duty cycle w/a battery sourced split phase inverter system capable of ~12KW peak will reasonably run everything I have without any concern. The default power source should always be Grid power which is currently by far the cheapest power source.
I would target 50% load cause like u said fuel efficiency is lost on light loads. That generator will burn close to the same amount of fuel weather it's 25% load or 45% load. Secondly and most important these gens are kind of sensitive to wet stacking. If u only run low load most times at least once a month u need to run 100% for an hour minimum to make sure you burn off any unused fuel/carbon in the engine. If u ever see wetness anywhere on the exhaust put 100% load on right away or u risk washing out the cylinders. Lots of surplus generators are in the auction because of this reason. Many many are just fine. I've had over 20 units and only one was bad and that's cause the exhaust flap was left open and the engine had water in it. I now have a 803 and I plan on doing something very similar use generator during day for house loads and charge lithium batteries especially in winter when only the furnace is running at night then at night run on the lithium batteries. This way too during the day the generator will have a good heavy fuel efficient load.
@@electromechanicalstuff2602 Nice info.. thanks.. you must be another MEP Flipper? The guy I bought mine from bought them by the Lot, pennies on the dollar from Gov't auctions. With most inverters you can select the generator Start/Stop battery voltages.. and Max charging current so your 50% load recommendation should be easy to set up.
@@markhall3434 exactly. I set up my buddies solar system in hawaii the same way. U can get auto start units for these too from greenmountaingenerators.com
Ya I flipped em for the first few yrs they came out. The auction prices in the north east of the country got too high for profit So i got out
@@markhall3434
Auto start.
So basically your inverter has an output to request generator startup and will have priority that if there is grid power to use that to charge and passthrough power to load. U can set soc for that command like for lead acid I'd do 70%-80% lithium would be 20%-70%

wow i'm amazed of the amount of features of the military generators(and the cleanliness of the power through the oscilloscope) , i thought that they were designed just to power aircrafts(that uses 400hz) but from your video i have learned that,military genset is 1000 times superior than comercial,with that... i just have to congratulate you for your initiative to upload something like that, I´m strongly encouraging you in the name of the whole community to tell us more about them(servicing wiring diagrams, servicing components and other devices not seen on comercial gensets),i have to ask do they have synchronizer for automatic paralleling with other machines? we'll tracking you continuously..........great job!!!! .
I have thought of making videos like that. I will in the future. Some units are 400hz the 60hz units are mep-802, 803, 804, 805, series. The 5kw and 10 kw do not have auto synchronous feature. But the military does sell a kit which is basically just a bulb to Identify when to energize the output contactor. The 15kw 804 and up do have the auto synchronous feature. I have a video on the 804 unit and u can see the switch for it. I'll find a video on how to synchronize them
czcams.com/video/pdKAM2Xrtjc/video.html
This is the older 002 and 003 models. They are the 70-90s air cooled units but the process is the same
look up ch-1 generator interlock switch kit from national RAM electronic. it works off the same principal. keep the main breaker from being in the on position while the generator breaker is on and vice versa
What makes these military diesels last longer than the cheaper one you showed is the fact that the engine it runs at 1800 RPM vs 3600 RPM of the smaller one. They make 3600 RPM diesels also and those will last a little longer than the gas versions but not alot more. The bearings and all moving parts of the higher speed engines wear out at a MUCH faster rate logarithmically.
The speed is a huge factor, that is correct but also look at the robust components of a diesel vs a gaser. The piston rods are twice as heavy, the blocks are twice as thuck, the metalergy in general is usually of a higher standard to handle the higher compression ratios, cylider pressures and torque.
300 RPM diesels like Listerines, you will to your grandchildren.
On the cheap one the scope was connected between line and the chassis. On the good one it was connected between line and neutral. Depending on the internal wiring this might not matter.
Hello if I were to pickup one I should really get one newer in year like 2006 and up. Nice video
I usually went for newer units but the most important thing to me was to make sure it was not a rebuilt unit. There is a small tag by the data tag that indicates an overhaul.
Do you have a frequency meter you would sell? The one on my 802a is jumping all over the place. Already verified good output with a meter
Unfortunately I don't. It is one of the gauges that fails the most because of its sensitivity. Mine is a bit sticky right now too. I parted out a whole mep-803 and that was the first part I sold
on the green mountain hyperlink scroll down and click on mep-802a generators and parts
How does it do with the inrush starting on the HVAC unit? We are going to build an all gas home (cook top, water heater, furnace backup) and will need one to just run HVAC/refrigerators like you're doing. I sold my MEP-003 and I'm torn between the 802a and the bigger 803a.
It does real good on my 3 ton 13 seer bryant AC unit. The only thing is you dont want much more then 2000 ish watts currently being used when it starts to keep the engine from boging down. So the days you know you'll be using it keep the toaster oven and every ceiling fan in the house on at the same time to a minimum. Myself to combat this i found a load manager from xantrax. Its called xantrex freedom sequence power manager. All your power runs through this first on its way to your panel. U can add some 15-20 amp 120v loads to it for shedding or what im going to do is utilize the built in low voltage relays to interupt the AC contactor signal wires. (The little wire going from your furnace to the outside AC unit). This way it will determin if theres too much load currently being used it wont start the AC unit or if the unit is on and someone starts the toaster oven and microwave and all the fridges kick on it will shit the unit off untill the generator can handle it again. All the treshoulds are programable and there's a few vids on CZcams about it. Even big natural gas whole house generators use this technique in the automatic transfer switch. I haven't done it yet but ill be going at it this summer.
czcams.com/video/_P6N6hG_LWU/video.html
Excellent information! Thank you so much for sharing. I didn't know the Xantrac device existed. Now to make my decision and this definitely makes it easier. Thank you!

Hey Bobby: Is this generator good for 24/7 running an off grid house?
FreemonSandlewould yes thats exactly what its designed for. You will only have to shut it off every 500 hours to change the oil. So every 21 days. You can hook up an aux fuel tank of any size and the on board fuel tank has a second float that with refill the onboard tank to 3/4 when it gets below half tank automatically with the built in aux fuel pump. Just turn the main ignition switch straight up and down to prime & run aux fuel position
Uhm, no. I'm a 91D20 :-) Hello from Korea.
Check LO 9-6115-641-12. 250 hours or 6 months to the service. Use cheap ole 15w-40. I normally see about 4000 hours out of an engine before I have to swap them, and swapping an engine is a pain in the ass. Also note that life really sucks when someone does an AUX fuel but the fuel level sensor is broken, and it pumps the whole barrel onto the ground overnight.
Know I guy who had a 15k military gen. Had power and was even heating his pool after a storm knocked out power for a week.
I have a video on a 15kw unit on my channel mep-804a
how did you obtain this unit? was it at a government liquidation sale? were you allowed to inspect the unit before placing a bid? how much was the purchase price? thank you for your time and look forward to a reply. I am in the market for a standby generator and looking for information on the subject of military surplus.
thomas marabillas yes govliquidation.com does allow squeduled previews but tge closest site to me is 3hrs away. I dont know if govplanet.com will allow previews. Look for reset tags the tan one have tgem more often. Dont buy it if it has that. Look for wet stacking around the exhaust manifold. They can still run but usually never at tge rated power tgey once could without a rebuild and they'll burn oil if they're westacked. I lile going for ones that have the exhaust flap in pristine condition to better ur odd rain water never filled the engine. U can get them depending on availability in your area and how many per auction and how many hours 1500 or less is a number i go for. They can very from $1000 to $2500 for a good one.
ebay just seen a fully restored MEP-003a selling for 5k but this guy is comparing apples to oranges. 1 cylinder vs 2 cylinder, portable vs not portable, not to mention totally two different types of generators....
Syc holic fully restored? By who? Some guy or the government. Like i said above if its been restored by anyone and has a "tier 2 reset tag on it" it's got a ton of hours on it with a few new parts to make it run and a new paint job. Yes i am comparing aples to oranges. Which is a good mil spec gen vs an average home owner style gen. They are very different. My point is those $1,500 or less consumer generators have "dirty power ". Everyone and there mother has heard that term before on gens. Now u know why people say that. If you are using a gen for your home backup just be aware that using "dirty power" is very bad for your electronic devices and it will shorten the usable lifespan of your devices.
you arent paying for clean power, they are designed for motors that dont care about dirty power like power tools.. just saying ya comparing apples and oranges. btw this was the one I seen. looks pretty mint to me. (ableit I wouldnt go purely on 'looks') www.ebay.com/itm/MEP-003A-MILITARY-MEP-DIESEL-GENERATOR-10KW-ONAN-803-802-002-MINT-REDONE-ARMY-/122912929883 I would also go out on a limb saying that coleman is a total joke, 100% duty cycle with a power factor of 1? lmao BULLSHIT... Also dont get me wrong Im not saying your gen isnt way better but that coleman is like a harbor freight special.... really isnt comparing the two. should pull the cover off the coleman see what kind of field flashing it does and is there a AVR etc also what does the sine wave look like under a load? should even be a warning on that manual saying dont use 'electronic devices' with said generator again just by looking at it screams to me power tools only...
Syc holic holy crap 5500 for a early 80s air cooled 003a with a new paint job. Those things didnt come with digital gauges either. Have you ever heard a 002 or 003 run? They are louder then that Coleman. They put out clean power too but man are thet loud. I usually get the 002 and 003 from auction for under $800 ive had 3 or 4 of them over the years. I give those ones to family memebers who live in areas with no neighbors. I've been trying to get ahold of a honda diesel 6kw so i can scope it and try to start a 3 ton ac with it.
I have an MEP-003A which is 10kw and air cooled. Bought this a backup to my Generac 20kw propane / natural gas primary unit. The Generac has an automatic transfer switch and will run my entire house including 2 central air units - 5 tons each. It will auto start and has circuits wired into house thermostats so it will start only one AC unit at a time. Runs the whole house with no problem. Bought the MEP in case of extended outages. Wouldn’t want to run the Generac more than 12 hours or so. The MEP will run for days at a time and will run the whole house with just one of the 5 ton AC’s running.
Doctor Goop ive run 3 3tons with a mep-803 also a 10kw but u would definatly see the lights dim for a sec especially if that start at the same time. Thats one thing generac buyers usually dont know too. Is there $10k units cant run more then a few daya without needing service. Hope u werent one of the people who figured it out after u bought it
This is old video but have a question hoping you have the time to answer.
My 2004 Motorhome has an Onan gold marquis 5500 on it. The hours are getting up there and at the moment in having to live in it while I build my shop and home. Have the opportunity to buy two of these with low hours and excellent working condition. Can I run my 50 amp motorhome off of one? The most amps I have ever seen pulled with both AC units running and all lights and electronics on is 27 amps.
Absolutely no problem
I really appreciate you answering. I got it set up but I'm not gett8ng ant power to my motorhome. I've tested with shore power and rv side is all good. Plug into generator cord wired exactly how you have it but have no power from gen. Have 110 from the generator sockets and all gouges show its working but I don't have power. 220 V on meter but nothing. Is there anything else I'm not turning on to get power? Does the ac interruptor have to be on?
@@arrowheadtelecom6561 yes the ac interrupt must be on

Mep-802 is 5kw rated 6kw actual
Mep-893 is 10kw rated 12kw actual.
Rated at high altitude to perform.
So at sea level u get a but more plus 300% starting surge
Hello I’m looking at one now 2009 Mep 802a with 125 hours no resets. It looks good on outside. I see some whitish staining on hoses like it was dripping on insides. He asking $3500.
Any black on the exhaust. That's the biggest thing to look for. Called wet stacking. If exhaust looks wet at all it's a bad sign
Could you do m a favor? If you still have the Coleman could you run a test on the sine wave with say a 1500watt space heater on it?
I do not but i sold it to a friend so sometime or never i might be able to
I'd really appreciate it. I have very similar model as a spare to a generac(chinese somewhat okay not really genset). I heard you just have to be really careful with loading and unloading to avoid spikes and dips and they clean up a lot with some resistive load on them.
If you can do a voltage check too, sometimes these things overrun and make a mess of the wave.
Oh something that may be easy for you there. Can we get a quick vid of that sine wave unloaded? It might even be cleaner. Electric motors spit out straight garbage into the system.
YOUR A/C COMPRESSOR IS RUNNING BUT BY THE LOOKS OF THAT COIL NOT FOR LONG!!! YOU FITTIN TO BE HOT THIS SUMMER!!!
As a licensed refrigeration technician who works on 500 ton units and smaller. That coil is not that bad at all. I wash em off several times a year. That r410 unit was 2 or 3 years old at the time of this video and it is now 10+ years old and still running strong. I've since sold that house made $150k on the flip to a Friend. now living on some property in the country that has two r22 units that are about 16 years old and run great also and i have two brand new 30lb bottles of r22 i got for free 5 years ago. I'm not worried at all. Plus don't write everything in capitals. It means you're yelling.
How do you come across something like this to purchase?
Used to be govliquidation.com online auctions. They had a contract to buy surplus. Now I think govplanet.com is the only one around. But auction prices have shot through the roof from people bidding on stuff they did not know anything about cause they heard a guy got few good units once soon a time. Many of the units have serious issues. Most of which a trained eye could spot. But people where bidding top dollar on units that where clearly only good for parts. I used to get a good 1,000 hour unit for $1500 and a parts unit for under $500 last time I checked they where selling for $4500 for any unit. I'd drive out of state up to 13 hrs away to pick up 4-5 units at a time and fix em up and sell em for $5,000-$6000 each.
In Germany we have these nice Stasi bunker 19 KVA Diesel generators from eastern germany, its also very solid and reliable, restored it a couple of years ago : czcams.com/video/U7vFHo2l1gY/video.html
Did you convert to single phase or are you only using two legs of the three phase?
PgPgDn they are 12 wire gen heads they have a reconfigiration switch on them behinf the gauge panel that allows for full power output in 3 different configurations. 120v single phase. 120/240 split single phase or 120/208 3 phase. I keep it on 120/240 spit single phase. Only the mep-002a 5kw, mep-003a 10kw, mep-802a 5kw, mep-803a 10kw units have this ability. The 15kw units and up are 3 phase only. However sewrzuk has a video showing how u can rewire the mep-004a to 120/240 low zig zag with some easy mods to the reconnection board but the newer mep-804a are only 10 wire gen heads and cannot be reconfigured for single phase

@@micah66048 better or worse ?
@@twofortyrida JP8 is a much thinner fuel. Also these engines should be around 1:16 compression ratio, while a commercial engine will be 1:21 or so. The upside is the military fuel and low compression ratio, combined with glow plugs, these will start no problem below zero.

Excuse me sir I own one of those 5000 watt gen and mine runs exceptionally
Well
TIM Williams what the Coleman? Ya they are great for power tools. U hook ur furnace or t.v. to it kiss years of operation good bye
I can run my whole house off of mine
But it's all in the way you turn things on I run mine through my dryer plug
TIM Williams watts are watts. But they are dirty watts clearly from this video you can see that. Using a suicide cord into your dryer plug is going to get someone killed and you put in prison for negligent man slaughter. Even if you do everything in right order. Good luck proving to the power company and the sherrif standing next to them that it wasnt you who killed the lineman down the road. It could have been the guy down the road who actually forgot to shut off his main breaker but. How can u prove it. Dont use a suicide cord. Its called that for a reason. Use a breaker panel interlock or a transfer switch. Someones life is worth more then the few hundred bucks it'll cost u

What rpm does the mep operate?
2thelightphoto 1800 like most diesel gens
how much does that thing cost generally?
5kw mep-002a units are between $2,000-$4,500 depending on year, hours and condition. There are some on ebay
Average price these sell for at surplus auctions?
Mark B price is extremely variable. Depends on state the auction is in, How many are in the auction, how many hours on unit, wheather its a tier 2 rebuild or not, weather its running condition unknown or been tested, how many hours on unit, visual condition, has visable wetstacking on exhaust manifold or not, has good condition exhaust flapper or not, on a trailer or not.
I usually go for around 1500 hours or less, no tier 2 reset tags, good visual condituon, no visable wetstacking, running condition unknown, good exhaust flap, with or without trailers, but newer Humvee style tires if i get a trailer. And anywhere from $1000-$2500 I'll spend and ive spend $2500 on ones with locked up motors on trailers
Still a huge bargain it seems. They would be using quality american made engines and components? In australia we would be paying 4-5k for chinese junk with similar outputs and higher end stuff can easily set you back 10k. Maybe I need to buy a heap and bring them back to aust.
Why did you decide to sell it?
i did not reply propery so check the comments i posted above
i am looking into buying one with 860 hrs is it too much hrs will it be needing an engine soon or they go the distance
Ive seen good runners at 8,000 hrs
I usually try to buy under 1500 hours. Oil change intervals are every 500 hours. Just look for wet stacking. Tar/ oily residue around exhaust manifold. Its from running without enouph load. 30% min load at all times.
Also look for a tier 2 tag by data plate that has year on it. Means its been oberhauled by the military but the clock gets reset. Usually they have had alot of hours on them to require an overhaul
@@electromechanicalstuff2602 is a generator having a tier 2 reset good or bad.
@@richardi1124 id go with bad but can be ok. Teir 2 reset means its been ovethauled. They dont replace everything. Just do the updates that are required and fix anything broken. Usually they only get teir 2 resets after a major breakdown. Like motor or gen head. They reset the hour clock. So u dont know how much time is actually on the unit. Alot of parts may still have 5,000 + hours on them. Its hard to say exactly how long it will last. They do go thrugh it and make it right but not as good as a non reset unit with less the 2,000 hrs if u ask me. Thats only my opinion. People may have diff opinions. Ive seen 8,000 hr units run fine. Ive seen units with 300 hrs on them destroyed because the operator let it wet stack. So it really depends. Wetstack is the biggest concern
6.25kw rated
I've seen huge piles of these thrown away in Saudi Arabia by the military. I was told it's cheaper to scrap them.than send them back state side. Go figure
Rayford Hickman if they dont spend the budget they wont get as much next year. Literally a donzen of the units ive gotton over the years where sabotaged when i got em. Usually oil pressure wire cut or something easy like that to cause it to not run and shut down via saftey fault codes. Its obvious they need new gens cus the others are "no good" the other 50% off all the units in the markets are usually junk cause of wet stack or watter got in the exhause and locked it up. The other half simple or no repairs
I have always looks at military logic as stupid
Military industrial complex don't make money on shipping only death
How many watts is it really?
5kw but I've ran 6kw for hours. But it had 300% starting surge
what does the battle switch do?
Bypass the safety shut downs. Over temp, low fuel level l, low oil pressure, over or under voltage etc. Genny gets hit by shrapnel it's more important to keep up comms and medical equipment than worry if the motor will be damaged
@@electromechanicalstuff2602 thanks for the reply. We are trying to get one. Just hard as we live in the bush of Alaska. One day.
@@curmudgeinnak they are cool. When they first hit auction I was getting them for like $1200 with less than 1,000 hrs. But then everyone and their mother started bidding on them and driving the price for parts units that had missing parts past $4k not knowing what they were buying. Main thing to look for is the exhaust. If it has black oil or tar like substance on it the motor has wet stacked. Sometimes u can fix it with just 100% load for 8 hrs sometimes u can't. U must maintain 25-30% minimum load on it at all times to prevent wet stack. Otherwise the engine won't get hot enough to burn the diesel completely coats the cylinder walls and allows oil blow-by that just gums up everything. So when buying and not sure wether u want a 803/10kw or the 802/5kw know that u have that minimum load requirement 1500 watts vs 3,000 watts continuous load can be as simple as a one or two space heaters. Mine only runs to charge my battery bank so that keeps my 10 kw unit at about 80% load for about 6 hrs
@@electromechanicalstuff2602 the 5kw would get run to charge my lithium at between 50 to 100 amps going into the batteries. Been using a crappy Cummins gas generator and it is horrid on gas. My yanmar is down and needs to be rebuilt. It is a old L90
Can you run this diesel generator Off of biodiesel?
Not sure haven't tried that but as long as it's clean I don't see why not
Old or military diesels, without the computer injection crap run fine on used cooking oil, used motor oil, any clean oil thin enough to pump.
where can i buy one ?
Govplanet.com I think but your paying top dollar these days. Ebay sellers too. Mep-802 = 5kw Mep-803=10kw both can put out 20% more then rating. Don't buy it if it doesn't run. Stay away from units missing exhaust flap and over 2000 hrs. Most units are in georgia right now.
How does the layman find something like this?
There was a time government auctions sold them for cheep like $1500. Now ebay or govplanet.com
not to mention way harder for some skinny crackhead to steal from behind your house
dollar for dollar comparison?
That's a 10 000 watt generator. I have two.
No it's not. The 802a is a 2 cylinder 5kw and the 803a is a 4 cylinder 10kw I have bought , repaired and sold 20+ of them. Now semantics. The 5kw unit can actually put out closer to 7kw and the 10kw unit can put out 14kw
shit, that little one looks like its from the 70s
No it's probably early 2000s
Put a little fuel in my 016b and ran it in a closed garage. No more rats.
I do not suggest doing that.
3kw nice units. I had a few
At 37 dollars a peace for 250 watt pannels you could put up 10 kw. Worth of pannels that never needs fuel.
Check out my latest videos. Lots of politics but in there is also solar videos. I didn't find $37 dollar panels but I did find $130 375watt used panels so in stalled 16 of them. Before that I installed 16 390 watt new panels at $300 a panel. When it comes to back up power one is none and two is one. Now that I have diesel and solar I sold my little 5kw yanmar diesel

You know sadly this video eloquently demonstrates the difference in product quality. Granted a new civilian version of the Mep-802 is probably ten grand or more. What's sad is the guy who will spend hard earned money on the POS.
w4csc i dont have a honda. So take a Video of it on a scope and put it in the description. Have fun changing ur oil every 50 hrs. Theses only need oil changes every 500 hrs. Id love to see that honda start up a 3 ton air cinditioner. There different yes but at .3 gal/hr not a fuel hog
I was going to say have fun changing your valve lash every 200 hours. The oil change is no big deal on the Honda.
There is a 7000is(4 grand) that started a 4 ton. It wouldn't shock me if he turned off everything he could if it started the 2 ton as well. I've heard of these units putting out way more then rated. They are freaking pricey though.

It'd be butter with a softstart kit(300 a pop just depends on your needs). Check out the new Westinghouse wpro8500 5% THD. I think even an inverter generator is typically in the 2-3% range and looking at that oscope just guessing it looks somewhere around what a 5% wave looks like too. 5% is supposedly some magic number. 9% works but is not ideal. Looks like the best consumer grade genset to come out in awhile. Looks like it's coming out of the same china house as generac. Not that that's awesome but generac seems to be at the top of the Chinese heaps along with champion. Nothing like this unit you have and I'm sure it'll bog down at the 11k surge. However it seems like the best your gonna get for around a 1100 new in box with a 3 year parts warranty from a big box store. Burns about half a gallon an hour at half load.
Bought mine for 250 bucks. 5000 kw, 479 hours and have a record of everywhere it's been. Not exactly what I would call spending a ton of money on a pos
@@JONNYGEEKMANG No doubt that Honda is an excellent unit. I would be interested in seeing what the voltage drop is on that thing during start up. When that MEP starts my AC I barely see the lights flicker any more then when I'm on grid. The 5-2-1 hard start kits are great I have them installed on every unit right from the get. Had a brand new Bryant installed 2 years ago I installed a 5-2-1 as soon as the van left my driveway. I was getting these things from auction running condition unknown for $900-$1500 and selling them for 5k I only had one bad unit ever after years of buying as many as I could every time there was an auction. but knowledge on what to look for helped my odds a bit better then buying any random unit.

Yes, yes --- but you're comparing apples to oranges. The diesel generator cost the taxpayers probably 25 times what that PowerMate costs and weighs 4x as much. You can forget about taking it camping for a weekend. But is it a better generator? Absolutely.
More like oranges to mandarins. Most ppl use generators for home backup. I evwn said the coleman was only good gor job site stuff. But home backup as the main use i wouldnt use one of those type of gas gens unless its an inverter style wuth pure sinewave
$3500 from me. current cl add detroit.craigslist.org/wyn/tls/5245633270.html
or you can get ones from greenmountaingenerators.com/product-tag/mep802a-generators-and-parts/or places like that who have also done load testing but there more like $5000 there
Bit of a price difference... lmao
Bit of a quality difference....
Pays for itself if your dirty power burns up your furnace control board and tv...
yeah, but it doesn't have wheels.. duh.

Actually, the horrible waveform of the garbage genset makes no differenceto any electronics manufactured since 1990. Every device uses a switching regulated DC power supply rated for ANY voltage from 80 to 300 volts at any frequency. The input you feed it is immediately rectified and charges a big capacitor to some dc voltage. The switcher's pulse width at a higher frequency varies to regulate the dc output voltage. It could care less what the genset waveform is,
K.... Dirty power is fake..... Inverter generators are just a money grab...... Or the low voltage power supplies are infact what fails when you run dirty energy. U can literally hear the power supplies whine when on dirty power. Ever actually own a radio or analog TV. Turn on a vacuum in the other room. What happens to your signal... Dirty power transient spikes ......
@@electromechanicalstuff2602 My diesel stepvan is powered by a Honda EU3000is electronic generator I got cheap. Its output looks great as Honda's sampling rate is higher. The BEST feature is ECO mode. Loaded at 1600 watts, eco on, the engine is only turning about 1500 rpm as output frequency has nothing to do with engine rpm. It's very quiet.
@@LarryButler-kp3se this diesel mep unit only ever runs at 1800 and it's always quite. Plus oil change intervals are 500 hrs. I can connect infinite size aux fuel tank and don't have to worry about the engine needing any real PM for 8,000+ hrs
@@electromechanicalstuff2602 Sitting in my yard is a 41-year-old Mercedes 300TD with around 900K on it. (it wore out odometers) It gets Rotella T4 dino oil every 3000 miles and consumes 1/4 cup between changes. It starts instantly glow plugged at 5F. 500 hours is too long for diesels as they contaminate the oil with unburned fuel and soot. ALL diesels have ring blowby.
Large diesels, like ship diesels, have extensive lube oil filtration systems because of this fact.
@@LarryButler-kp3se just what the manual says. I've seen this units at auction with over 9,000 hrs on them and I know the government isn't going to do more oil changes then recommended
6kw, 800lbs.....whats the point. Just get a NG or LP 10-24kw.
Quality. Those NG/LP air cooled motors won't last 1/2 as long. They need oil changes over 200hrs this one is 500 hrs. At 400 hrs the NG Needs valve lashing this doesn't for 5000 hrs. NG 10kw has no surge rating. So don't expect to start a 3 ton ac unit with it. This has 300% starting surge. The NG is just an air cooled lawn mower engine this is an onan diesel made for industrial equipment. The NG is a slip ring exciter that adds distortion this is brushless exciter with grid quality sine wave. Because it's water cooled its way quieter.
This service must be done by a certified generac tech to retain your warranty.
I've seen these military units with 8,000 hours on them regularly. I have a friend who used to service the whole house units and the valve seats usually only last 2000 hrs and then the head needs to be changed.
www.generac.com/service-support/faqs/maintenance-kit-faqs/what-maintenance-do-i-need-to-do-and-how-often
Look up generac service schedule B at 400 hours which is only 16 days of run time u have to lash the valves
Plus this is portable as long as u have a machine to move it. Mines on a trailer. It also has the capability of 3 phase output. I installed an automatic transfer switch and control board for automatic start in the generator. But if your not capable and just want something u can call a technician out for repairs I even recommend the whole house units because not many people know how to work on these military units.
I paid a hospital clinic $500 for my 33KVA diesel genset, including the hot start switchgear. It's Cummins engine had 220 hours on it. I paid $1200 to ship here. Long cables feed power to my neighbors who fund the underground 250 gallon fuel supply and maintence. We're out of power about 30 seconds.
@@LarryButler-kp3se you make my point. A mep802 is 6kw....go big or go home.
I just wish that the people that make videos like this knew what they were talking about, this was just a bunch of BS
Other then I said commutator instead of slip rings . What else did I say that was BS? Diesel doesn't varnish like gas and does have a longer shelf life. As long as you keep water out of diesel it stays good a very long time. The THD on the Coleman can and will damage your sensitive electronics. Brushless generators are typically less noisy because of there very nature. There are more reasons for the better THD I can explain them better now if you'd like to know about them.
