- This video describes the conversion process for configuring an MEP-004a or MEP-005a military diesel generator to single phase operation.
I have done this conversion on several generators and thoroughly tested it; it works well.
Follow this video EXACTLY. One mis-connected wire can result in a short circuit that will damage your generator head, control circuitry, or worse~you!
Follow this video at your own risk; I accept no responsibility for anything that happens during this modification!
Hello Matt, my name is Eric, i am using my sister's youtube account. i have a MEP005A generator that i purchased 2 yrs ago. i have followed your directions on how to convert it from 3 phase to single phase and it works great!! i have recently hooked 2 air handlers w/ emergency electric heat for a load bank. With both air handlers at full capacity it registers 130%. The generator compensates and performs correctly at all times. At 130% it holds steady power and as of yet i have not tripped it out. it is a very strong generator. Thanks for your video on how to convert my generator MEO005A
Glad I was able to help!
It's a good feeling to know that there are knowledgeable people like yourself out there. These beautiful machines can be a bit intimidating for people like myself. Thanks for sharing your knowledge.
UPDATE...
I took the connection board up today... found the copper buzz bar mounted on the bottom of lower connection plate. All is good!
thank you for all your information/research that you have done on these generators.
I am trying to do mine. I have the Buss bar on the bottom also. Had me worried when I could not find it THANKS.
The biggest benefit to the conversion is that you can get your full 30kw out of the generator in single phase. If you leave it in 3 phase, you can only get about 60% of its rated load. Also, some single phase equipment does not like 120/208 (although most appliances/tools run just fine on it). If you ever anticipate needing 3 phase, and you don't need more than about 20kw of single phase, and all of your loads are fine with 208v, then you can leave it as is.
I just performed this conversion to my 004a and hooked into my home. The process was very well documented and everything went flawlessly. Thanks for the video. The gen set runs everything in my all electric house and shop no problem
I bought my load bank from a local generator installation shop. It was designed to be permanently installed as a dummy load for a 300kw generator. I modified it to work on low voltage, and modified it to be able to "scale" the load. Before I found my current one, I was going to build my own load load bank using recycled electric baseboard heaters. 500w halogen lights are also a good cheap load...
Thanks! Glad I could help! I wish more people had that attitude toward solving problems...
Got it running, making 240V, installed and hooked up last weekend. Thanks for all your help and for nuking this out. I never would have figured this out without your post.
Thanks for the reply. Just after I sent the message to you I saw that the MEP-814A was a 400hz unit. Darn, it looked like a good unit coming up for auction and only made in 2006 with 29 hours on it. Right now I'm looking at bidding on an MEP-004A mounted on an M200A1 2 1/2 ton trailer.
Thanks a lot for your response. I'm having a little trouble identifying the smaller wires that need to be moved around to complete the conversion so I might just leave it the way it is. Thanks again.
You will need to wire up L1 to one side, L3 to the other side, and L0 to the neutral. This will give you single phase 120/208. All of your 120v loads will be fine. MOST 240v loads work fine on 208; some synchronous motors (well pump, air compressor, A/C pump) may not be rated to run on 208v. You'll find that most 240v appliances will show 208v-240v on their ratings tag. I ran my shop and my house for a long time on 208v (before I came up with the single phase procedure) with no problems.
Matt , I really have found your videos helpful,keep up the good work. I have recently purchased an MEP 805B 15kw gen set I am interested in doing the three to single phase conversion if possible? Your thoughts.
Sorry Matt , it's an 804B
Thank you for an informative video, I wish you would show a single phase conversion on a MEP-804A 15kW Generator.
Cant be done.
You can just use 2 of the 3 hot legs in 3 phase; but you only get 120/208 instead of 120/240 (some appliances don't like 208). Also, you can only get about 60% of the generator's output this way. After reconfiguring, you get 100%.
The proceudre is very similar; the modification to the voltage reconnection board (cutting the bus bar and running the jumper) are exactly the same. I'm not certain on the wire movements under the board...I don't have an -006a right now so I can't go check either! I will send you an email...
Thank you for all of your generator videos you helped me get my mepoo5a up and running grate did know they put out power thanks
Great video Matt, Smoksak, had not heard of that site yet.
It is normal to see the T10, 11, 12, 13 bar rivted on the underside of the board; lots of generators came this way. The bars on the top board are normal and need to be left alone. To cut the bar, most people leave it in place and use a small cutoff wheel in a dremel. I have also seen people remove it completely. It is more difficult when it is located on the back side of the board, but still possible.
Thank you, I have a 15kw mep 004a 60hz generator head and other parts for this unit. It has 950 hours.
One major variation I found from the video - the two MEP-004s I'm doing the bus bar was on the bottom of the connection plate - same location as the instrument wiring. A lot more work to pull the bar - modify and then replace. I'm not sure which years of MEP-004s change the location of the bus bar but this should be noted
There is no correlation to years/serial numbers/etc. to the bus bar location. I have run into both styles...not too difficult to cut the bus bar on the bottom, but the work area is tight. I just use a dremel and the work is done in a few minutes. I do address this in the Steel Soldiers forum, but not here in the video. Sounds like you worked around it and got it running...good work!
Nicely done - thank you for the quality help - recycling this expensive hardware is a benefit to the end user, the community and the tax payer!
Looks like there is enough space to install some rotary and toggle switches in the control housing to make it a variable output generator, the possibilities are endless!
Thanks for the reply, with the battleshort on the day tank would fill and then start and run fine until the day tank ran out.
terry marshall OK; it sounds like the "run" relay isn't being engaged. Do you have the tech manuals for your generator? I can point you toward the correct page/schematic/part and you can troubleshoot from there...
sewerzuk I.m back to work on this mep-004a same problem, it will run for 15min and then run out of fuel, engage battleshort run for 15min then out of fuel again. i cant seem to find the page i need thanks.
Most of the generators have an overspeed reset button on the side of the speed switch (it is a metal cylinder or rectangle, on the left side close to the fuel filters).
Got it sorted. Since the bus bar was on bottom I had to remove bus bar on top from T12 to T6 - bingo - powered up 240 single phase. Bottom line is the video is very good but does not precisely address MEP-004 from later years. So do your homework, understand the drawings and get it working. Mine took 3 hours with a couple reworks. Tonight the house is powered up!
Mat, I have a MEP 004a. In back of the control panel there is a box on the right side approx. 4" x 8" with a bunch of wires going to it. The box is dripping considerably what looks like tar at the bottom of the box. What would you do about this? I have not started it to check out the unit. Just got it. I believe it was create approx. 1985 . Kris Church
It would have been a better video if we could have seen more of what you were doing, or at least post a drawing between each event so we can follow. It is clear that you know how to do this but to give that knowledge to others is another thing altogether. A simple drawing could be a lot of help when you make those changes. Thx for sharing.
I have a pretty thorough writeup on SteelSoldiers; though it's been several years since I was active there.
and then use the battery cable jumper to go from T6 to T2 - tight to get it underneath:)
Hello, I followed your instructions a couple of years ago and it worked like a charm. I wound up the selling the generator to someone who really wanted it, so bought 2 more generators, an MEP-804A and an MEP-804B. Will this same conversion work on those as well? Appreciate your time. Vince
i don't have tech manuals but after about 5 or 6 times of running it started to work. I let it run for about an hour, it seems to be fine now thanks.
terry marshall No problem; if you can, you should put that set under a heavy (80% or more) load for a few hours; it will take care of the carbon/soot/etc. (wet stacking) and will also turn up any fuel related problems. If you would like a copy of the tech manuals, send me your email address and I will email them to you.
@remantrans I would verify the readings at the load terminals with a digital voltmeter; this will tell you if the connection problem is with the instrumentation/control wiring, or with the actual generator leads. I still suspect that one of the wires you moved is in the incorrect position. It is also possible that the set you have was incorrectly wired in the first place (I have worked on some of these that came into my shop incorrectly wired).
The MEP-814a is a 400hz unit; if that is indeed what you have it cannot be used for conventional 60hz power. The frequency is determined by generator head design and there is no way to convert it to 60hz without swapping the generator head. As far as the single phase conversion, I'm not certain; I've never had an 814 in my shop, since they are almost useless for any civilian application (except as parts for 60hz units).
400hz is for aviation use, if he knows a small airline that needs a ground power unit he can set it up for 115VAC 3 phase, he'll also need to install the 6 pin ground power adapter with a 15-20' leads.
@remantrans Are you saying that you followed the video and have already completed the conversion? If so, and you are still getting 120/208, then you most likely have either not cut the bus bar, or run the jumper to the incorrect terminal on the reconnection board.
Just what I was looking for. Great, thanks for the video
Love your presentation!
I have a MEP-805A. It has a movable plate on the voltage reconnection board that allows you to have 120 volts, 3 phase at L1, L2, and L3 (to L0). If I elected not the convert it could I, or should I connect L1 to one side of my panel box and L3 to the other side? Will the variation in the phases mess up any 240+/- appliance or tool?
Matt-Will the mod you made on the MEP-004A(15KW) be the same for a L3 MEP-805B 30kW? I thought you said yes but wanted to make sure. thanks
Not normal to have the reverse power light lit; does the light go off if you operate the test/reset switch, or does it stay on all of the time? If the breaker stays shut even with that alarm, then the alarm circuit is faulty. L2 will still read a voltage, but the L2 terminal is not used once the conversion is done. Only L1, L3, and L0.
I would like to know how much fuel this generator would use per hour of operation and if this could also be run on a vegetable oil- diesel mixture, please.
Can I buy one from you?
OK; if the alarm resets, then all is fine. Sometimes, some of the sets I work on will develop spurious alarms during startup. As long as it resets then nothing is wrong. Yes, L2 will have 120v on it with no load. Depending on how much load is on the generator and how balanced it is, that voltage could be much higher or lower than 120v. That is normal...
Hello.
Would yo be familiar with the 10Kw MEP 803a TQG's that are flooding the market?
I am trying to find the physical location of the K12 relay and diode CR5?
It is getting to the point I'll have to pull most of the exterior panels to try and find them
This "single-dual" zigzag provides 2-phase 120v system with 180 el. degrees voltage vectors. Single phase system can have only ONE live wire and in this case is 240v only. My friend have similar DG and uses it in euro 220-240V 1-phase system to get an emergency power for his cottage. In his system "L1" is a live wire, "L3" is N and grounded, and "N" is left unconnected.
We're talking terminology here; but you're correct. Normal household current in the US is split phase 120/240. That is accomplished by grounding the center tap on a single phase 240v transformer. This allows for two 120v legs, and the use of 240v by combining the two hot legs. The generator is simply wired to match this normal household configuration; more useful for most people than the stock 3 phase configuration.
The most powerful appliances are connected to 240V, small - between one leg and neutral to 120V. Have bought many audio amplifiers from USA on eBay, small models all have 120V power, the hi-power professional models - 240V. But i don`t know, what advantages have that split-phase system in compare to european 240V single phase. Some peoples talk about, that 120V is not so dangerous as 240V, some say that this is historically formed system, that can work on today and do not need to invest a lot of money to transfer it to any other.
the reason it is safer is that there is no more than 120v from either hot leg to ground. So, if you accidentally touch a hot leg in a 120/240v split phase system, you will only get shocked with 120v. If you accidentally touch a hot leg in a true single phase 240v system, you get shocked with 240v.
Whether you use differential circuit breakers on your split-phase system? These are absolutely necessary in all home power systems in europe as described in EAC rules. 10 mAmps for wet places and 30 mAmps for generic household. It takes about 10-15 milliseconds to cut the line if you accidentally touch it.
Matt , Great video of 3 phase to single conversion. Is the MEP-805B converted the same way or different?
I have the same question. If you got the answer please share it. Thank you -Shannon
Cant be done to 80x series gensets. Only on 00x gensets.
thanks for you reply. If you think of anyone who may have the other wire configurations please let me know. Tim
Hi Matt Verley, great video!! I found you on Steel Soldiers and this video is exactly what I'm trying to do. Everything is pretty straight forward as you explained it well but the only problem that I'm having, and I hope that you can advise me is this...
The wires that you listed to move are different from what I have.
I have 2 wires on my #12 lug 110C16 & 110D16
I have 2 wires on my #8 lug 108D20 & 108A20
My unit is an MEP 804A 03/2004 Any help is greatly appreciated. Lol I'm trying not to short anything out. Hope your still available or if anyone else has ran into the same scenario with their machine??
Single phase is common household current. 3 phase is commonly used in industrial settings. 3 phase motors (and conductors) can by physically smaller and are more efficient than an equal power single phase motor. The specifics are too detailed to get into here. If you google "difference between single phase and three phase" you will find all the info you will ever need...
Hi Matt
Do any of these military gen sets have automatic frequency controls?
How would a person regulate frequencies with varying electric loads ?
Hello Matt,
Wonderful video. I just purchased a 804b and am going to attempt the same conversion after I studying the schematics.
Do you ever offer your services, for compensation, to evaluate things like this?
Thanks
Scott
did you get yours sorted out? Im getting ready to do the same thing
Hey Scott, I have also just purchased an 804B. It's been a year since your post, did you go through with the conversion? It seems that the only difference is the engine (Yanmar vs Isuzu) from the "A". Was the wiring numbered the same as the A? @MattVerley feel free to comment if you read this. Great videos on these generators.
you are a clever fellow ive just brought a 13kva 3 phase cable coming out 3 phase what can i do to make only 240 volt what do i need ? thanks
I'm not sure if this is a problem of mine or if I just need help with the wiring, I have a m5 military generator with the four-cylinder Flathead engine with a Hobart generator zxb. Now if I had to flash the generator to make it generate electric how would I do so? If you had one of those generators I would make an awesome video
Wonderful and enlightening video, thanks.
This is a great video, very informative.
Hi Sewerzuk, I tried to reply to your respose to me on your other video, where I asked, where to get parts, but it didn't work somehow. Thanks for the tips, Oshkosh has all the parts that I need, except the Frequency Transducer, but I opened the faulty one (nasty stuff) it turns out to be a quite simple circuit, I think I can repair it. It is only 2 Ic's, 1 transistor and a few passive components. I do actually have a comment about this video; I started to go through the single phase conversion, but this Mep-005 is different from the one on the video. After removing 9 nuts (it was configured for 240/416) I lifted the jumper board and there was no copper bussbar visible. I was puzzled at first, but after removing the posts and looking under the panel I've found it in the same position that it is on yours, but mounted underneeth all the nuts holding the wires. I wasn't happy about the idea of removing all the nuts that held the bar, instead, I just removed the thick cable from T12 and conected it to the bottom of T2. I did all the other moves too, except there was no need to move X12EG16N from T12 to T11, because it is still connected to T11 by the busbar, that I didn't cut. I hope this may help someone...
+ltstluc1 Yeah; common to find the bus bar on the bottom of the reconnection board. Most people have successfully cut it in place with a small cutoff wheel on a dremel.
+sewerzuk No doubt, it can be done that way, but in my case I had to also think about the possibility of 3 phase use of the set in the future, so because I didn't cut the bar, everything can be re-connected in the original way if needed. I read it somewhere amongst the comments of one of your videos that you have a manual for this genset, can I ask you to email me a copy to ltstluc@gmail.com. Thanks very much in advance.
ltstluc1 email sent
+sewerzuk Thank you for the manuals. I finally got to finish the single phase conversion without cutting the bus bar. When I actually got down to do it I realized that I had to move all wires from T6 to T12 as well. I didn't think it through previously and now realized that by cutting the bar and using a jumper cable you are actually moving T12 and T6 together to T2 because the jumper board connects T12 and T6 in the low voltage configuration. I will start the set in a couple of days, still need to complete my work on the alternator that had 2 diodes shorting. I will let you know how the test went, but I'm confident that it will work just fine. If anyone would like to do the conversion without cutting the bar I'll be happy to give detailed instructions.
Your videos are great, I just started buying these Generators and am having trouble with a MEP 004A 188 Hrs on the clock. the fuel pumps will only come on with the battle short on. I'm suspecting its bypassing a relay but don't know where to look. Thanks.
terry marshall If the set is not running, the fuel pumps should only come on when the battleshort is in battleshort. There is a "run" relay that energizes once the generator comes up to speed and powers the fuel pumps on. So, if the day tank is empty (or low) you would need to fill it by leaving the battleshort switch in battleshort for a few minutes. Otherwise, I just turn it on for a few seconds when I am starting to make sure I hear the pumps start up and then slow down.
I have seen units with 8000 hours on them. I would consider that a lot. I typically don't purchase any with more than 2000 hours on them...that's my own personal line.
I have heard that some of the newer 805's had 10 lead generators in them. If that is the case with yours, then my method will not work. If you have a 12 lead generator, then the process should be very similar. The bus bar being on the underside of the fixed board is common...I have seen more on the top, but most other people seem to find them on the bottom. Same procedure...just cut it to isolate T12
Hello,
Thank for the video,
On a forum a person was doing the same change, and the entire process is the same but.. his last connection is different, he connected T12 to T13, please advise on this difference with your instruction (T12 to T11), here are the full instructions.
"I moved X8HH16B from T8 to T11. This results in the VR seeing the following voltages:
T11 and T9: 240v
T9 and T12: 120v
T11 and T12: 120v
I moved X8A16B to T3. This results in the thermal watt converter seeing the following voltages:
T7 to T3: 240V
T7 to T10: 120v
T3 to T10: 120V
moved the lead (X12EG16N) from its original position on T12 to T13, restoring the neutral. "
Love the videos! Very instructive. Is it possible to convert an MEP-814A to single phase? Would it be the same procedure as you demonstrate here on the MEP-004A?
Is their a way to make this 3 phase to single phase change to a MEP 804B
Will this conversion work on a 1980 30 kw MEP 114 A? You have the best videos on these generators keep it up.
The conversion to single phase would work; but the 114a is a 400hz machine. Almost useless in a civilian application, unless you intend to power a military surplus radar set or some other kind of custom project.
So what is 400hz and what does the hz need to be for a 120/240 house? What will happen to my house if I used the 400hz?
Mike Carlson household current is 60hz (in the US). If you tried to supply your house with 400hz, it would immediately damage any digital electronics, motors, and anything with a transformer. That's about 95% of most household electronics. Heating elements would probably be ok, as would incandescent light bulbs. Generally speaking, a 400hz set is useless for civilian use, except to cannibalize parts for a 60hz set. The military uses them to power specific precision equipment, like radar systems.
I guess I need to sell it . What you think it is worth? Only 55 hours. I need a part for it and was wondering if you could point me in the right direction to find it? I need the part the bolts to the bottom of the radiator where the radiator hose connects to and controls the shutter. I tried Osh Kosh already they where out.
Hey Matt could he not use the engine for parts for a bad MEP 004a the mounting is the same
Hey Sewerzuk,
keep up with the great work, love the channel. I have just picked up a MEP-804a I am getting it ready to start, changed filters, added fluids etc. The problem I have is no power to the panel. No lights no faults it won't crank with the dead crank switch. I can crank it if I jump the selenoid. Is there a main fuse or breaker that I can check? I have the manual and it is still a bit vague. I would appreciate any advice. Thanks.
Good morning Matt. I just acquired a 1985 mep005a and when I excite the field with the start button my voltage will come up to around 100 volts but when I let off after setting the hz. The voltage goes away. Any ideas of where I should check next.
Matt I have a MEP 105A that has been converted to single phase along time ago .It has been working fine but today when any load is put on the generator one leg will drop to around 35-45 volts .Can you help me ?
1979 mep 005 generator with white 6cyl diesel engine starts then stalls shortly after releasing start switch. Fuel pressure from transfer pump appears to be weak(very slow flow). Manual states 130 psi max. Could you tell me where to find a transfer pump and idea on fuel pressure
I have a unit just like the one in the video. Need small square part mounted on day tank on generator side. Any help for part will be appreciated.
I just got a 004 and was looking to try this, I saw a post mentioning resistors across the ct to adjust the trips and gauges. There appears to be 2 ct blocks. Which ct gets the resistors?
Have you ever Installed a ADVR-054 on a Military 005A ??
hello Do you any information on converting a kohler 50 kw model 50R0ZJ81 from three phase to single phase? If you do anything would be great. Thanks in advance
Ok, fired it up and short circuit fault light! Suggestions?
Matt, great stuff. Which one of your videos do I follow to reconfigure my MEP-804B 3 phase to 240 single phase? both look easy enough, just don't sure if the wires on the bottom need to relocate as in one video. Thanks.
Hi Steve, I am wondering the same thing, converting 804b to single phase. Did you ever find the solution? Thx
hi, what is the purpose of reconfiguring. couldnt it just work by leaving one hot leg off of your connections. or does it not have a neutral without reconfiguring.
thanks Ken
The lead #s you mentioned to move around. Are those labeled on each wire? And if so is it common to loose the label with age? I am looking at purchasing one of these for Home backup use and will do this conversion on it.
MrBellboy1234 the numbers are stenciled on the wire every few inches. Easy to find the designations, but you might need to work your way back up the wire a bit to find a legible one.
I was shopping for a b/u generator for home on these gov sale sites. Would you recommend one of these units over another for smooth operation and power, also ease of swapping to 1 phase. Would prefer up to about 25 kw.
Hay matt thank you for this video. So i have the mep006a you said this is very similar just wanted to know what are the steps for it
I'm in the middle of doing this on a MEP-005a. Simple question, but if my bus bar is not in between the two boards as the one was here, but on the backside (underneath) where all the loads are tied in, I'm assuming I cut it the same way, right? Any benefit to bringing it up to the other side? The top board actually has double bus bars riveted into it between T1 and T4, T7 and T10, T9 and T12 etc. Is this standard?
Is it possible to convert a mep-701a to 120/240? I see it already has two outlets that are 120/240 but would that be enough for lets say a back up generator for a few appliances?
Am I understanding you correctly that after doing this the voltage will adjust up and down automatically based on load?
I have an MEP-005a that is missing a few parts. I have the manual but cannot find a parts list. Do you know where I can find a parts list? Also where are the best places to get parts. (I found a couple but they are very expensive)
I have really enjoyed your videos. They have helped a lot on fixing mine.
Hello Sewerzuk,
I have a PU-794/G 20KW which is a MEP-004A with sound enclosure and a upgrade in power output from 15KW to 20 KW.
When doing the conversion from 3 phase to single phase, this unit doesn't have the copper buzz bar that needs to be cut. Can i make one, and then do the change of the circuits on the back of the board?
I'm not getting power to my fuel pump but if I jump out the fuel pump and hold the start button and stop position to stay running soon as I Let Go it shuts down this is on a mep-004a I noticed this the fuses what could it be
I am working on a MEP004A. We fooled with the speed control, caused the generator overspeed fault light to come on. The reset will not reset it, what might be the problem.
I just purchased a mep005a and saw your video on the single phase conversion. Is there a safety/longevity benefit to the conversion or could I just hook up to two of the three hot legs for home use? I have heard about unbalanced loads but I am not an electrician. I appreciate any advice you can give.
I have an MEP 701A. I cant find good detailed info on how to do 220/110 split phase. Can you point me to a detailed resource on this
Hi Matt, I’m a pilot and aircraft owner as well. Great video, do you know if this can be done with a MEP805A? Can’t find much info to convert it over to 120/240 if it’s even possible.
I dont know if you ever found the answer, but no you cant. The 804 and 805 have 10 lead generator heads and cant be converted. You could either use an auto transformer or sell it and get an 005. Or the 803 comes pre wired for single phase. Hope this helps someone.
Great video Matt would this same scope of work also work on a L3 MEP 806B 60kw 3phase thanks
Hello, thanks for the video a lot i have to questions if you may, in T8 I found XBA16B and another one labeled 8 only, 2nd question when i do this switch if I connect a cable to L1 and L3 which is neutral in this case i get 240v as a single phase ?
I've been reading through a few threads on Steel Soldiers you wrote about reconfiguring the MEP-004A to 120/240 low zigzag. What type of load bank equipment would you recommend for testing the 004A? I just bought one and am picking it up on Friday. Once I get it home I'd like to test it but I'm not sure what piece of equipment to get. Any information on this would be greatly appreciated. Thanks.
Sorry, but I'm not really in the parts business for these! I did have a partial ASK for an -004a, but somebody recently purchased it...
Ive watched this video and when I tried to convert mine,its a MEP004a the thing I found was that my bus bar is riveted on the bottom of my plate.have you seen this before? Im thinking it my be a replacement board?Im having a diffacult time finding anyone who knows about these gens,This one is for my Fire Dept. could u please help?
Do you know the process to convert a MEP 805B to single phase? I have looked through steel soldier but haven't found anything
Hi i have a military generator MEP-806A 60KW GENERATOR thAT WOULD START RIGHT UP BUT WOULD NOT OUT PUT NO VOLTAGE COULD YOU TELL ME WHAT I COULD CHECK
I would check the voltage regulator A5 if it's bad you have to change the T1 transformer voltage potentiometer and resistor out in a set... there's a tcto on the voltage regulator installing a 5 amount fuse I believe in line with f1 and fm for field flash circuit
5 amp cartridge fuse
F1 and F2 is your 24vdv exciter field
Have yo ever converted a MEP-006a to single phase and have the video's for it.
What is the purpose of the 3 phase anyhow? I mean, what would you use it for. I mean, 1 phase vs 2 phases vs 3 phases, to those that don't know, (like me)
Hey Matt,
Im looking at doing this same conversation with a mep007B. Is it exactly the same?? Thanks Mike
I plan to use this to power a few RVs which as you probably know are all 120v. After the single phase conversion, what would I need to do in order to get rated power with just using 120v. Tying L1 and L3 together and using a single lead? I'm doubtful.
Basically going from 120/240 at 7500 watts per leg to 120 at 15,000
Some of you can help me with my question: I just bought a MEP 004 and I do not know how much diesel per hour this equipment consumes and I have to leave it working for 24 hours.
Thanks for your help.
Sewerzuk, would it be possible to do a Video on converting the MEP006A genset to single phase particularly changing the secondary (meter) wiring?
On the unit I have it has two secondary wires to T12 - X12EG16N and X12P16N so I can move the X12EGN to T11 not sure what to do with the X12P16N. On the T8 there is only one secondary wire X8E16B
Thanks for the vid!! I am wanting to make the same modification on my MEP-805A. Is it possible? I took the plate off and it looks like the bus bar is behind the plate. I want to somehow get single phase 240 V with it.
Thanks!
Hello there, great video to watch real well expained.I am looking for some information in regards a Deutz generator.I have been asked to carry out a job on 2 x Deutz F6L912 generators with Stamford UC224D alternators, 3 phase configured for star-series 480V output, 52 kW and 60 Hz,but i need to rewired to single phase star parallel 120/208V so it will be compatable with an inverter.
If i could get any help from you i would be really greatful.
Many thanks..
Mick O'Connor.
Can we convert Mahindra 20kVA 3phase Generator to Single phase
Can you git someone to hold your camera so we can watch every step you do? Mark
Have a MEP-005a and someone has changed the volts to 120/208. I went to the voltage reconnection board to change it to 240/416 and I notice that the bus bar is gone. I can only get about 300v out of it as it is. What does the bus bar do? and if Can I put it in to get back to 3 phase and 400 volts
tim Zimmerman The bus bar is the "common" tie point for all of the windings, and the neutral connection. The bus bar must be there if the generator makes 120/208 power; it may be riveted under the main board.
