Generac rv altenator wiring

Sounds like the valves in the Carburetor are stuck open, or the choke is stuck closed. either way the Carburetor will need to be removed and serviced.

Usually generators that have stood for a very long time loose the magnetism in the ignitor coil magnet. With care, if you can find the low voltage wire into the generator 'motor' you can apply a 9v battery briefly to it and spark it into life. Use the generator if you get it generating, for a good period and don't leave it unused for a long while.
*IF YOU DONT KNOW AND UNDERSTAND ELECTRICITY DO NOT TRY THIS. GENERATORS CAN KILL*

Try putting 12 volts across the commutator at the brushes. Ust a low current battery nor a car storage battery.

Good luck,

Randy, connect up your volt meter and try manually reving up the engine. Even a few hundred RPM can make a big difference in the generator output.

If that resolves the problem, then you need to adjust the high speed settings on the motor.

check voltage input at voltage regulator, then check output from
the regulator.

regulator maybe need to adjust or broken

Check for low oil or over temp.

this sounds like a problem with the windings on the generator. This is an induced voltage and should be within 10% of the vac you ask it for

check the oil sensor circuit. I know when I take out or short out the sensor ckt on mine, it'll keep on running. low oil isn't good for any motor.

If you dont find a solution here. Call Generac in Waukesha WI. and get the number for Robert Schwalm Co. He is the best in the Country for Generac I used to be #2 but I havent worked on all the new Generacs. Give me an old RV unit and no one is faster!
