How I converted an Onan generator for stationary use. These are designed for RV use and can be had fairly cheaply. I paid $500 for this one and have maybe $700 total in it.
Ur fricken awesome! Love your style, easy to follow and understand. My late husband didn’t have time to teach me stuff so I’ve had to hunt for men like you... no nonsense straight shooter. Thank you
THIS IS HOW I FIXED MINE, IN THE CASE OF.... "I CAN'T START MY GENERATOR" It's has been two years since last time it was running, so I started by checking oil level full at gen dipstick (it won't start if low oil because of sensors) then I checked gasoline more than 1\4 tank in the RV (also safety sensors), sparkplug checked for good spark, also checked the manual reset circuit braker ( to be ON) at front motorhome engine compartment for 12v current to the generator to be able to start it, also cleaned the carburetor and even installed new one but same situation, then checked wires and found some has been chewed like gum by rats at the back of starting switch generator panel so I replaced them, at this time the generator started but stay running only by keep pushing the switch on all the time, so then finally I knew it was internal electrical problem from the engine itself, so I took the generator out from my RV to work in my garage, (I did this by myself with some tools and old Mayan tricks ) lol, it's really heavy for one person. I disassemble the unit at my garage and started by removing the cover, then the cooling fan or flywheel unit (it's 2 items in one) until finally I was at the gen rotor and brushes assembly area and this is what I found: one more wire chewed by filthy rats plus the stinky rat nest in the middle of the generator motor coil, I fixed the wire and sanded the commutator copper contacts where the brushes are sitting becouse they were real duty with old urine from the rats, and of course I got rid off the stinky nest, lol!!! Then I assembled everything back together and... bingo it's runing like a champion!!! For this project materials involved was about $60.00 including an aftermarket new carburetor and an harmonic balancer/steering wheel puller (available at any auto parts for $25.00) to pull the aluminum fan out and (flywheel). Just picture this: (Any gasoline engine run smooth if gasoline and DC current aren't interrupted) so following this important principle you'll always find the problem to be fixed. Also if you have a onan microlite 4000 like mine, don't run it for more than a minute without the cover because you'll cook the engine real fast, also keep the eye on the aluminium fan and your fingers after cranking it in case you missing one or two members...just kidding, lol!!! After testing the gen with the help of a gasoline container, a piece of hose and 12v battery, I did put the air cooling assembly back and the rest of components including the cover, then it was ready to be installed at my RV. Once the gen was installed back at my motorhome I started it to be tested for 120v electricity but not before flipping the AC circuit switch (on) at the gen starting control panel (sometimes hiding under or around the panel) to be able to transfer power to my RV GFCI main outlet and electric panel as well, my motorhome it's equipped with GFCI so I reset it and tested for green led light indicating power is ready at my main breakers panel, so I turned my main breaker (on) along the others ones but no power was present at my breaker main switch (faulty main braker) so I flipped it many times, sometimes you can make it work again, mine did work, lol!!! I'm happy because everything works now including the refrigerator for cold drinks and AC for this crazy summer, lol! Later I'll buy me a new main braker, for now this is a resurrected generator story that needed to be shared. If this can help eaven one person to save time and $$$ it'll make me more happy, thanks for reading.
The Onan manual recommends running that thing for two hours every month to keep it working. So either drain all the gas out of it completely or you will be running it a lot. Many RV owners have found out the hard way that it needs a new carburetor if you let it sit for a year without running it. I'm thinking about pulling mine out of the RV and replacing it with batteries. $3,000 generator replaced with $3,000 batteries and a few solar panels is much quieter. They call that thing " Micro Quiet " and it is huge and noisy as hell. Gotta love marketing.
Good job man. Just got myself a 6.5 emerald 3, researching ways to make this heavy thing mobile with a tank and battery attached. I like the way you did yours, very compact and easy to move around. Think I'll do something similar with a little bit larger off-road tires. Appreciate the video!
Nice job! I am thinking of replacing my 4KW Onan generator on my RV with a smaller inverter generator. I might use the Onan as backup power for my house.
Great idea , doing the same with 7000 watt onan 120/240 , one question , I want to wire 240v outlet for a welder i know theirs 2 hot and 2 negatives how would I write the 30 amp outlet only uses 3 wires 2 hot 1 negative , does it matter which negative I use since theirs 2 wires ?
I have same unit will power house garage had electrician wire it up back feeds from shed to home remember to shut main off to home works great used boat tank gas storage
I have an older model-lots older! Did the transformer have a black, white, and ground coming out of it for connections in the receptacle box, or did you have to do some electrical work to get to AC receptacles?
Good day all !! Awesome set up . Do have a question though. I have an onan genset my self in a old 84 pace arrow motor home. I can't get mine to run . I can push the start button at the generator and will turn over but no spark at either spark plug and no power to the fuel pump any ideas? Thanks for the video Sir !!
pretty slick. I would like to do the same thing. I bought a bfa 4kw. I think it is older than yours. it had the same fitting on the shaft for a boom truck. I am waiting for manuals on ebay. there are some parts missing like the coil and plug wires,start stop swich and housing, but I don't know if this was supposed to have a mother board or not. do you happen to know. got from pick and pull for 38 bucks, but I got some work to do. it is a 120/240. parts are expensive. do you know of any cheap onan parts places, maybe used parts. thanks

Really nice man. Thank you for the vid
Fantastic job well done buddy
Nice setup! Thanks for thisvideo. Very helpful

Excellent video.

very nice job.
Nice Job
Great idea , doing the same with 7000 watt onan 120/240 , one question , I want to wire 240v outlet for a welder i know theirs 2 hot and 2 negatives how would I write the 30 amp outlet only uses 3 wires 2 hot 1 negative , does it matter which negative I use since theirs 2 wires ?
Hi. Great video. I know it was posted a while back but is the red wire going to the starter solenoid? I couldn’t see in the video. Thanks!
I have same unit will power house garage had electrician wire it up back feeds from shed to home remember to shut main off to home works great used boat tank gas storage
How did you get the shaft in the generator for coupling
I have an older model-lots older! Did the transformer have a black, white, and ground coming out of it for connections in the receptacle box, or did you have to do some electrical work to get to AC receptacles?
Can you help me wire the output to a outlet like that
Good day all !! Awesome set up . Do have a question though. I have an onan genset my self in a old 84 pace arrow motor home. I can't get mine to run . I can push the start button at the generator and will turn over but no spark at either spark plug and no power to the fuel pump any ideas? Thanks for the video Sir !!
make sure the ground connection is good but im also guessing the fuel pump is stuck, they're about 80$ new

This is a very nice set up... I wonder how difficult it would be to convert this to LP gas?
look up propane kit on amazon or ebay for onan looking to do the same
plus u will need this kit with an on demand regulator or it will not work right
ive got 4kw onan will run hole house set ike yours
When I unhook my battery mine dies immediately
That's because they don't have a charging system built into them. They use the battery of the motor-home or whatever they're used in.
