I just use The light line (it is the secondary winding on the coil probably) so it gives 3-30Volts of alternating curent depending on RPMs, so i just use rectifier, kondensator and voltage stabilizer from china that is rated for 5-35V and gives stable 12v max 3A, this is so much better even if it doesn't light at idle, because you wouldn't have a hole in your side cover.
Awesome, I knew this could be done. And I've been thinking of a method that it could be done but first I had to look at the size of alternators seems like you've already figured it all out. thanks for the video ❤
Neat installation, But please don't take this the wrong way: Why don't you mount the alltenator ABOVE the motor mount? That belt is hanging out in the wind, and that alltenator is directly behind the front wheels splatter in any wet weather. Won't it interfere with the peddles? Great idea, "China Doll" engine bikes can use a electric system. Again very nice work.
I just subscribed. I found your product first and then looked to see if you had a channel. But im going to enjoy going threw your vidios. You make an awesome product. Im going to be placing an order in the near future i hope i currently have a 6 volt generator system
You must have the patience of jobe I'm very impressed I will love to get my hands on your generator alternator excuse me I was at a very good job for quite a while till I got injured in my own home not covered by the company so now I'm unemployed and nearly broke can't ride a bicycle anymore that I have to pedal can't hold up my motorcycle anymore because it's my legs that were injured I'm currently running a cheap kit on a bicycle would love to get my hands on an electric start version with your alternator preferably engine mounted though I'm sure I'm going to have to relocate my carburetor to accommodate the space please continue your patience with all of us
I need one of these for real tho this bike is my daily rider everywhere and I wanted to do a radio install but need this to charge the battery and keep it going
Do you do custom outfits? Say, charging system, headlight and two small LEDs that woukd fit inside antique taillight? Also like a switch to cause either taillight to flash as a turn signal, and an always on/off for both. Then a USB port for charging a device?
Will do. It's currently unavailable but I'm working on revamping it to eliminate the big hole in the side cover,as well as a brand version that will be completely encased inside.
I ride with a super Polymer lithium battery 12v 3.8AH its small very lightweight and it wires to my rear and front motorcycle LED 5 3/4" headlight also is rechargeable, and the battery last 14-16days till it dies out, could upgrade to the 12v 20aH battery but this one has worked for me about 4-5months
elitew4rri0r _ Good idea, but this is a generator only, it doesn't work like an electric motor. Some of the 49cc pit bikes have that function, where the starter turns into the alternator after the bike has been started.
Cody Watson , it's the cinch that's really close. The actual alternator is inside a steel guard that's clamped inside the chrome cinch, and is actually about an inch or so away from the exhaust. But depending on your bike, you could move the downtube clamp down a little farther away from the exhaust.
Yep, it needs a grommet or bearing seal of some sort. If I'm going to have a hole may as well put the V pully right on the gear to keep it as flush as possible. Then your cover would come in as a seal also. I want one.
Cory Miller , yes that would be optimal, I might think on that idea. Have a bearing included in the kit. Since the end user is the one to drill the hole in the side cover, I didn't want to make it"the hole had to be exactly yadda yadda yadda size, our it won't work". Lol. Without the seal, there's a little more room for slight error with the hole size, with the sacrifice of a completely sealed side cover. But, if done carefully, there's very little room for crud to get in there. But I agree with you, sealed would be optimal.
I haven't seen that. I have seen the auxiliary charge coil that goes inside the case,but the power it puts out is negligible,as there's not enough space inside the case for the windings needed to produce real usable voltage and amperage.
Those exist now. Its the yd100 I think. Problem is that the internals have alot of plastic and a small chain drive next to the crankcase. Could be problematic if you don't completely re machine parts in metal. Its like 280 bucks. It has more torque than stock and has centrifugal clutch
I have two of the electric-start 2-stroke kits, bikeberry sells them, and they are called BT80's, it's actually a quality kit except for the pull-start, they have little plastic ears that pop out and turns the engine when you pull it, when the little ears break-off, it sounds like the engine is going to lockup any second, other than that, I love them.
Hey I have a 66cc bicycle with a front wheel 48v 1000 watt electric hub I wonder if I can use this alternator to charge my batteries while using my engine , then I can switch to electric with charged batteries ? Let me know
Bill Collins , yes, a PMA still outputs ac voltage. So a regulator/rectifier would still be necessary, unless it was a very low voltage output, and you plan on running only filament bulbs, as they can run on both ac and DC, as long as the voltage doesn't run past their maximum input voltage ( that for if your using ac voltage with no regulator)
Will, you told me on the group you would help me with pulley dimensions.. If my generator system doesn't pan out then I want to try your method. Please PM me with the dimensions.. I will video and photo how everything goes together..I think I can duplicate your mount..I do appreciate your help...BTW,,excellent videos very self explanatory.Thanks bro,, much appreciated.
In a stock 66cc the only test i had was with and without the generator installed,driving the same 2 mile course around town. I did notice a 1-2 mph difference in top speed,but no way to tell if it was the generator or possibly headwinds/weather conditions. I didn't notice any difference in acceleration. Top speed without it was 37mph according to gps speedometer. 35 to 36mph with the generator installed.
Ammo tin and a 12 volt battery, all the lights you could want. Just take the time to put it on the charger once every couple weeks. I'd rather do that than this because now you loose your all weather riding ability once that hole goes in your clutch cover
It's advertised as 12 volts. It will achieve that bit only at wide open throttle. And only gives about 1/4 of an amp. There simply isn't enough windings on the coil to produce any real usable voltage/amperage. Plus it shares the magnet with the spark plug coil,and robs you of power for the plug
I've been using An auxiliary coil for over 30 years to charge my battery. It puts out 1.3amps at Idol. I have no issues with it pulling power from the bike or the coil. I am charging a 18 amp Hr lithium battery with it and it runs everything you can put on a bike, headlight tail light turn signals and all my accessories and the best part about it is it's all inside the case and watertight, the only thing I have external is the battery which is in a weatherproof enclosed case, along with my voltage regulator and fuse box. If you can handle basic electricity and Ohms law this is the way to go, especially if you're on a budget. Keep it simple and factory and most important. Have fun doing it.👍
Hi Keith. The charging system hasn't been produced for a couple years now. Parts prices went through the roof and most importantly, the company that made the alternator itself went out of business.

Matt,thanks for the comment. This version of the charging system is no longer in production. I am currently working on version 2 which will be a totally enclosed system. I post updates and pics on my Facebook page. Heres the link. Thank you facebook.com/Verybrightbicyclelights/
251omega actually with most standard pedal cranks, they clear by about a 1/4". It's designed so most riders won't have to buy wide pedal cranks. That saves money. Good eye though!
Well, I just adapted one of those 80cc engines to my 1981 Stump-Jumper and the engine was too wide for my cranks. I tried to get a set of offset cranks for my Shimano Bio-Pace chainrings but not available. I slid the engine up the front tube and made a cross bracket for the rear mount. I had to lengthen the chain about 7"... works great! I would like to find rubber motor mounts, and an engine-mounted chain-tensioner pulley that's loaded with a heavy spring... chain keeps getting extra "play" as the stock pulley vibrates out of adjustment... hard to clamp it onto a tapered tube and I don't want to drill an index hole...!
The pulley gearing is designed to work from the rpm of the main shaft, depending on how fast or slow the jackshaft spins, would determine the final output voltage of the unit.
Good question,T.J. , I have other videos on CZcams showing the alternator working, and I'm also a member of many motorized bicycle pages on Facebook. You can look up very bright bike lights on Facebook, or under my name, Will Kidd. I have many happy owners of the alternator. You could ask around in there, also have a web site, visit www.djwillk.wix.com/vbbl. My number is listed here in my logo, and also on my web page.
I get the point that there's only so many places you can hook a pulley up, but drilling a hole in the cover that protects something that must stay clean from debris never made any sense to me. I've seen others do big holes for some super clutch design, but that all limits where you can and when you can ride these
Agreed. Pros and cons no matter what. I guess it just depends on the individual and their particular riding habits and road conditions./weather conditions.
For everyone here they sell a piece that goes on the other side of the magneto coil. Its is a separate coil that produces power. Much simpler than all of this nonsense. You can get it from gasbike for 25 dollars. Just go to gasbikes website and search "12V Generator" in their search bar. Theres also a video on youtube of how to install it.
Drcool52 , yes the little mini gen that doesn't work. It's impossible to get any workable voltage out of those small windings, no matter what the claim is. There just isn't enough room under the side cover to put the amount of magnet wire you would need to achieve any real voltage. You also have to take into account that you need rectification of the AC voltage coming out, to make it into usable DC voltage. After experimenting with that particular"mini gen", the most voltage I could ever get out, at wide open throttle, with no load on the rear wheel, was about 3 volts AC. After rectification your left with around 2.2 volts DC and 1/8 of an amp. My system is designed for people who want to run full lighting systems on their bikes, as well as a few accessories.
Thats why you get an atv battery and a rectifier. During the day your battery charges and then at night you should have plenty of power to run a lighting system as long as its led. As for your claim that you only got 3 volts and an 1/8 amp I doubt that a bit. I'll come back here when I get one and show my results. But I do respect that you actually argued your product instead of just deleting my comment.
Drcool52 Not at all, I appreciate the input. I've had a couple mini gens, one from the eBay seller"mightywonderful creations" and another from gas bike. The eBay seller also sold a small external black box that zip tied to your seat post tube. It contained a half wave rectifier circuit, as well as a few voltage doublers. That's how he was able to get that small winding to produce 12 volts from 3. But, if you double your voltage a you half your amps. That's why it just can't work. What can you run from a 1/8 amp? Maybe a small flashlight LED, if you're lucky. My system was designed so you could use anything you want, 24 hours a day, lights, USB chargers, etc. It's modeled after a motorcycle system, just not as many amps. Mine tops out at 14.8 volts and around 8 amps. My complete LED lighting system only draws 1 amp. I have the voltage regulated and rectified with a universal 4 wire regulator/rectifier. This system is the culmination of about 2 years of experiments. I can give detailed answers but that would not be in this thread. Lol.
Drcool52 Been looking for that thanks, but how many lumens of light where do you get the lights? I got Solar lights got over 7500 lumens but its battery I was thinking of having it run off magneto so I can run day and night without electric drain loss.
This altenator would take away a huge amount of your already small amount of horsepower. 2 horsepower is what the engine already puts out on a dyno test.
Agreed Shane. But as long as your load doesn't exceed the input,there's only a negligible load put into the engine. In past tests I've only experienced a less than 1mph difference in top speed,and no noticeable difference in acceleration. At half throttle, the alternator is putting out 14.7 volts dc and 7 amps. A fully loaded led lighting system should only draw about 3.5 amps. That's a great point you brought up though.
Will Kidd I have to 80cc Motors I need to start charging batteries with this is the best idea I have found yet there is not a place to buy these online do you have a location are these customes and how can I buy these
You can contact me directly at verybrightmotorbikes@gmail.com, and I'll get your direct contact info. I can give you all the information you need on the charging system.
torque is not measured in grams... also the amount of torque required to turn an alternator is dependent on how much electrical load is demanded from it.
bradley morgan gram force millimeter? Decimeter? I can't remember. But it's a miniscule amount. With my lighting kit only drawing about 1.5 amps, and that's with high beam, brake lights and a set of turn signals blazing, the generator has no problem keeping the 12 volt 5 amp battery fully charged. It's putting out 12.9 volts and close to 4 amps at idle speed, and then 14.8 volts and close to 7 amps around 1/2 throttle. That's the bike being under load, with 180# rider. Under normal lighting conditions, headlight on low beam, and just tail lights, the current draw is 0.86.
that's not bad, pretty efficient lights it seems. but torque units are a measure of force (usually newtons in SI) multiplied by a distance (meters). so a torque of 1 newton meter will rotate a wheel that's one meter in diameter with a linear force of one newton along the outer rim.
bradley morgan thanks for the explanation, I was trying to explain the necessary forces needed to run the generator. It's almost negligible, but lacked the correct terminology to explain it so most could understand. I know it uses neodymnium magnets with North/South running the length of each magnet, so while it's being attracted to one set of windings, it's simutainiously being repelled by the previous. It's quite a remarkable little unit. Took a bit of research and a chunk of my own change in failed attempts before I found it.
Good idea! Very poor execution! Try using a small brushless motor with a thin profile and fix it so the shaft directly coupled to the small gear with a cover that covers everything so that you don’t have a hole in the gear case.
Might as well make your own and not pay all this money. I built mine from said Gas bike Gen and also used the 12v gen magneto as well. Will Kidd is a lie.
zakarya hamzeh that's incorrect. This generator only takes 0.05 nanograms of torque to keep it going. That's less energy than is used to snap your fingers. It's a zero drag alternator, that's been field tested for over two years.
@@QuinnHartmann Do you know how small that value is? Also, nano grams isn't even the correct unit for torque, it's newton meters. Btw, 0.05 nanograms is 5*10^(-11)g. Even if he meant to say newton meters, such a small amount would suggest that he has an impossibly efficient system lol.
I appreciate the input. But those " 12 volt coils" that go inside the case dont put out any real usable power. You possibly get around 12 volts at wide open throttle, but only about 1/4 of an amp. You cant charge a battery with that tiny amount of power. The coils simply do not have enough windings to produce any sort of usable dc voltage. I tested them in depth before building mine.
@@djwillk I apologize for sounding like such a dick, clearly, you have done your homework and know what you're talking about. I'm thinking about buying a high compression head, any input on that?
@@GhettoRanger01 you don't sound like a dick at all. Lithium batteries can't be charged using a "flood charging" method,which is what those in case coils,and my system as well,utilize. They would destroy the Lithium batteries and possibly cause s fire. No bueno. High comp heads are nice but i believeyou'd need a little internal engine work to really make them sing. Not my area of knowledge really. I just make accessories..
@@djwillk there's a video I made how I got my lights hook up. It's just as bright then on this video and you are running down your power on your engine meaning it won't go fast as it should.
@@derekthompson6653 I agree. I've got some lighting systems that are rechargable, so no alternator, bit over also got systems out there that use a battery and my generator system, that have been going for years. I believe options are good. What might work for one, might not speak to another.
I just use The light line (it is the secondary winding on the coil probably) so it gives 3-30Volts of alternating curent depending on RPMs, so i just use rectifier, kondensator and voltage stabilizer from china that is rated for 5-35V and gives stable 12v max 3A, this is so much better even if it doesn't light at idle, because you wouldn't have a hole in your side cover.
Nice job. Wish I saw this on my build of something like this. Mine was off magnet side and mounted under the motor same idea!
Awesome, I knew this could be done. And I've been thinking of a method that it could be done but first I had to look at the size of alternators seems like you've already figured it all out. thanks for the video ❤
Neat installation,
But please don't take this the wrong way:
Why don't you mount the alltenator ABOVE the motor mount?
That belt is hanging out in the wind, and that alltenator is directly behind the front wheels splatter in any wet weather.
Won't it interfere with the peddles?
Great idea, "China Doll" engine bikes can use a electric system.
Again very nice work.
I just subscribed. I found your product first and then looked to see if you had a channel. But im going to enjoy going threw your vidios. You make an awesome product. Im going to be placing an order in the near future i hope i currently have a 6 volt generator system
When is the A/C System coming into play?
Clearly, in this day of global warming, a necessity, not merely a luxury like bright lights.
If I could afford I would just buy your kit..It loos a lot neater than my version.

I just found this video, so please excuse me if I missed any other videos, but is this kit out somewhere where I can purchase it?
So how much for your system and about how much for the battery and why don't you provide a pre drilled cover?
A 12 volt or greater lithium ion tool battery and a LED head light works great and runs for hours.
Absolutely! I've seen a few riders modify the charging base, so it acts as a holster for the battery. Clicks in and out for quick battery changes.
Yeah but it’s annoying just like u
Does the wather and sand go in to from that hole?
I need one of these for real tho this bike is my daily rider everywhere and I wanted to do a radio install but need this to charge the battery and keep it going
I concur. I would buy this right away for my 80cc build

Do you do custom outfits? Say, charging system, headlight and two small LEDs that woukd fit inside antique taillight? Also like a switch to cause either taillight to flash as a turn signal, and an always on/off for both. Then a USB port for charging a device?
Cody Watson , I've done something similar to this for a rider in Canada. So yes, I'm sure we could work together to get you the rig you need
Good idea with the belt cover
You really should have a link in the description of the video to where the kit can be purchased
Will do. It's currently unavailable but I'm working on revamping it to eliminate the big hole in the side cover,as well as a brand version that will be completely encased inside.
It's an awesome project and idea to do but compare that to a drill battery it can't be beat
I wonder if you could connect this to a CDI?
just fit a custom fit old school dynamo to the wheel :) they are 6v but still work
Nah, it's been done. Too simple.
How about an alternator for a honda ghx50 or husaheng engine

elitew4rri0r _ Good idea, but this is a generator only, it doesn't work like an electric motor. Some of the 49cc pit bikes have that function, where the starter turns into the alternator after the bike has been started.

Two alts would be excessively cool on my fat bike too.
Ten years ago some guys figured out the correct bulbs to use to run off the magneto white wire, are these kit even coming with the white wire anymore?
I haven't seen that. I have seen the auxiliary charge coil that goes inside the case,but the power it puts out is negligible,as there's not enough space inside the case for the windings needed to produce real usable voltage and amperage.
Neat idea, but over enough time I’d foresee the tuned exhaust pipe snapping off due to added weight

If I remember correctly the early Ford engines used a generator for a starter by reversing the polarity.

You can look up very bright bike lights on Facebook, or under my name, Will Kidd. I have many happy owners of the alternator. You could ask around in there, also have a web site, visit www.djwillk.wix.com/vbbl. My number is listed here in my logo, and also on my web page.
a cosa serve il video se non ci sono in descrizione i link dei componenti.... boh
I get the point that there's only so many places you can hook a pulley up, but drilling a hole in the cover that protects something that must stay clean from debris never made any sense to me. I've seen others do big holes for some super clutch design, but that all limits where you can and when you can ride these
Agreed. Pros and cons no matter what. I guess it just depends on the individual and their particular riding habits and road conditions./weather conditions.
Cmon put a link to this thang and what's the price??

but they are currently sold out.
@@djwillk thank you!
For everyone here they sell a piece that goes on the other side of the magneto coil. Its is a separate coil that produces power. Much simpler than all of this nonsense. You can get it from gasbike for 25 dollars. Just go to gasbikes website and search "12V Generator" in their search bar. Theres also a video on youtube of how to install it.
Drcool52 , yes the little mini gen that doesn't work. It's impossible to get any workable voltage out of those small windings, no matter what the claim is. There just isn't enough room under the side cover to put the amount of magnet wire you would need to achieve any real voltage. You also have to take into account that you need rectification of the AC voltage coming out, to make it into usable DC voltage. After experimenting with that particular"mini gen", the most voltage I could ever get out, at wide open throttle, with no load on the rear wheel, was about 3 volts AC. After rectification your left with around 2.2 volts DC and 1/8 of an amp. My system is designed for people who want to run full lighting systems on their bikes, as well as a few accessories.
Thats why you get an atv battery and a rectifier. During the day your battery charges and then at night you should have plenty of power to run a lighting system as long as its led. As for your claim that you only got 3 volts and an 1/8 amp I doubt that a bit. I'll come back here when I get one and show my results. But I do respect that you actually argued your product instead of just deleting my comment.
Drcool52 Not at all, I appreciate the input. I've had a couple mini gens, one from the eBay seller"mightywonderful creations" and another from gas bike. The eBay seller also sold a small external black box that zip tied to your seat post tube. It contained a half wave rectifier circuit, as well as a few voltage doublers. That's how he was able to get that small winding to produce 12 volts from 3. But, if you double your voltage a you half your amps. That's why it just can't work. What can you run from a 1/8 amp? Maybe a small flashlight LED, if you're lucky. My system was designed so you could use anything you want, 24 hours a day, lights, USB chargers, etc. It's modeled after a motorcycle system, just not as many amps. Mine tops out at 14.8 volts and around 8 amps. My complete LED lighting system only draws 1 amp. I have the voltage regulated and rectified with a universal 4 wire regulator/rectifier. This system is the culmination of about 2 years of experiments. I can give detailed answers but that would not be in this thread. Lol.

Been looking for that thanks, but how many lumens of light where do you get the lights?
I got Solar lights got over 7500 lumens but its battery I was thinking of having it run off magneto so I can run day and night without electric drain loss.
You would have to find a light you can wire up. Theres plenty on ebay just make sure its a 12v light
Awesome,, I can make this pulley on my lathe.
Con una pila de motoneta basta
This altenator would take away a huge amount of your already small amount of horsepower. 2 horsepower is what the engine already puts out on a dyno test.
Agreed Shane. But as long as your load doesn't exceed the input,there's only a negligible load put into the engine. In past tests I've only experienced a less than 1mph difference in top speed,and no noticeable difference in acceleration. At half throttle, the alternator is putting out 14.7 volts dc and 7 amps. A fully loaded led lighting system should only draw about 3.5 amps. That's a great point you brought up though.
Shut up and take my money!
Lol. I can do that.
Will Kidd I have to 80cc Motors I need to start charging batteries with this is the best idea I have found yet there is not a place to buy these online do you have a location are these customes and how can I buy these
You can contact me directly at verybrightmotorbikes@gmail.com, and I'll get your direct contact info. I can give you all the information you need on the charging system.
torque is not measured in grams... also the amount of torque required to turn an alternator is dependent on how much electrical load is demanded from it.
bradley morgan gram force millimeter? Decimeter? I can't remember. But it's a miniscule amount. With my lighting kit only drawing about 1.5 amps, and that's with high beam, brake lights and a set of turn signals blazing, the generator has no problem keeping the 12 volt 5 amp battery fully charged. It's putting out 12.9 volts and close to 4 amps at idle speed, and then 14.8 volts and close to 7 amps around 1/2 throttle. That's the bike being under load, with 180# rider. Under normal lighting conditions, headlight on low beam, and just tail lights, the current draw is 0.86.
that's not bad, pretty efficient lights it seems. but torque units are a measure of force (usually newtons in SI) multiplied by a distance (meters). so a torque of 1 newton meter will rotate a wheel that's one meter in diameter with a linear force of one newton along the outer rim.
bradley morgan thanks for the explanation, I was trying to explain the necessary forces needed to run the generator. It's almost negligible, but lacked the correct terminology to explain it so most could understand. I know it uses neodymnium magnets with North/South running the length of each magnet, so while it's being attracted to one set of windings, it's simutainiously being repelled by the previous. It's quite a remarkable little unit. Took a bit of research and a chunk of my own change in failed attempts before I found it.
Good idea! Very poor execution! Try using a small brushless motor with a thin profile and fix it so the shaft directly coupled to the small gear with a cover that covers everything so that you don’t have a hole in the gear case.
A motorizada já não tem muita força,com este dínamo vai pesar para o motor e força-lo, muito trabalho para nada
Might as well make your own and not pay all this money. I built mine from said Gas bike Gen and also used the 12v gen magneto as well. Will Kidd is a lie.
You might as wel say good bye to torqe
zakarya hamzeh that's incorrect. This generator only takes 0.05 nanograms of torque to keep it going. That's less energy than is used to snap your fingers. It's a zero drag alternator, that's been field tested for over two years.
@@djwillk How did get that statistic? Surely you can't measure that.
Dr Din why not?
@@QuinnHartmann Do you know how small that value is? Also, nano grams isn't even the correct unit for torque, it's newton meters. Btw, 0.05 nanograms is 5*10^(-11)g. Even if he meant to say newton meters, such a small amount would suggest that he has an impossibly efficient system lol.
You did it the hard way, they make a coil that uses the flywheel magnet to generate 12 volts soooooo genius, you built an inferior product.
I appreciate the input. But those " 12 volt coils" that go inside the case dont put out any real usable power. You possibly get around 12 volts at wide open throttle, but only about 1/4 of an amp. You cant charge a battery with that tiny amount of power. The coils simply do not have enough windings to produce any sort of usable dc voltage. I tested them in depth before building mine.
@@djwillk Unless you use it to charge lithium batteries maybe.
@@djwillk I apologize for sounding like such a dick, clearly, you have done your homework and know what you're talking about. I'm thinking about buying a high compression head, any input on that?
@@GhettoRanger01 you don't sound like a dick at all. Lithium batteries can't be charged using a "flood charging" method,which is what those in case coils,and my system as well,utilize. They would destroy the Lithium batteries and possibly cause s fire. No bueno. High comp heads are nice but i believeyou'd need a little internal engine work to really make them sing. Not my area of knowledge really. I just make accessories..
That's to much work just get some lights on the bike look at my videos I got the easy way to get lights on bikes.
Different strokes is why. VBBL lights will pass a dot inspection to get your bike street legal, in States where it's viable to do so.
@@djwillk all I did was I want to Walmart got some led strip and got a battery on ebay hook it up and it work just find....
@@djwillk there's a video I made how I got my lights hook up. It's just as bright then on this video and you are running down your power on your engine meaning it won't go fast as it should.
@@derekthompson6653 I agree. I've got some lighting systems that are rechargable, so no alternator, bit over also got systems out there that use a battery and my generator system, that have been going for years. I believe options are good. What might work for one, might not speak to another.
@@djwillk I agree with you too.
