Great to put a face with a voice. You have helped me with my Onan Emerald 1 4000. Your advice & instructions over the phone plus these videos have made fixing an Onan a cake walk. Thank You.
I looked all over for which lead/wire went on the top and bottom connectors, F1 goes on Top F2 on Bottom blade connector ! Thanks. I know this is 6 years old video
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!
On my Onan 4000 microquiet, spec K, the white brush block wires are labeled F+ and F- and I do not know how that translates to F1 and F2. Any help would be appreciated.
I changed the control board in my onan 7000 but now only getting 51 volts out of it. I did pull brushes and polish the...?? like you stated. brushes first then the voltage reg or is there a way the test the reg?
No way to really test the reg, I have a 5500 BGM model from 1995. I was having starting up issues, replaced control board, cleaned slip rings, and a full tune up. Ended up being a partially bad regulator, and just replaced for the heck of it. I went through all diagnostic steps through the service manual, all tests showed everything was good. I had a gut feeling reg. and once I replaced it, genset has been giving me no issues, ran 8hrs. straight, starts right up.
hi my cummins onan 4000 generator starts and after 2 or 3 minutes it shuts down. the gas filter is new also the carburettor and the air filter. the gasoline is 93 octane and is new.
Where are the points located on the emerald I do not see a cover I do not see a hiding place I have followed the coil wire goes inside down into the bowels of the machine looks like a lot of things have to come off
Hello Lucy, please head over to www.flightsystems.com and click the "BOOK NOW" button in the upper right hand corner. You will be able to schedule a time for our specialist "Tom" give you a call. Thank you for watching!
after searching high and low.,. is this as close as I can go❔ I need to know what are the symptoms of brushes expiring🤔 or what can cause the onan to start at a L0W power of 87 or so volts.,. and slowly increase to operating 120 v . . . H E L P . . . PLEASE 🦧

Is it possible to check and clean the brushes on an Onan 4000K while installed in RV compartment?
Will the same 1" stripped wire work for KV generators?
Will a magnetic T-25 help to help from dropping the screws?
On my Onan 4000 microquiet, spec K, the white brush block wires are labeled F+ and F- and I do not know how that translates to F1 and F2. Any help would be appreciated.
So do you carry the brush blocks? And great video,i did not know this was that simple.
do you show how to troubleshoot the ignition and fix ?
When taking the brushes out I would have taken the top bolt out first. If you drop it chances are it would set on top of the brush housing.
I changed the control board in my onan 7000 but now only getting 51 volts out of it. I did pull brushes and polish the...?? like you stated. brushes first then the voltage reg or is there a way the test the reg?

Does the generator need to be removed? I have an onan 4000

Whats the part#
after searching high and low.,. is this as close as I can go❔
I need to know what are the symptoms of brushes expiring🤔
or what can cause the onan to start at a L0W power of 87 or so volts.,. and slowly increase to operating 120 v
. . . H E L P . . .
PLEASE
🦧
john bennis
excellent video, thank you
Can I make my 7000 watt onan 120 volt make 220? And what is needed
No cant be done
