Onan generator making grinding noise while cranking

I have a 94 Onan 4000 microquiet generator that makes an intermittent grinding noise while turing over before starting. It is very loud and reminds me of a starter grinding on a flywheel but I'm not convinced that is what it is. Is there something else it could be?

If it walks like a duck and quaxks like a duck?

If it grinds like a starter ?

Your alternator would hsve to be in absolutely unaerviceable condition to match a noise a starter makes.

Check the ignition circuit, and trigger coil for correct resistance on the trigger coil, and the ignition coil. The trigger coil is a small module on the engine shaft near the flywheel.

I have an Onan 3600 microquiet lp. I made the mistake of hooking up a jumper box to the battery with the cables crossed,now it blows the 5amp fuse that supplies power for starting. hope I didn't fry...


It certainly sounds like you have damaged the control board. If you cranked it with reverse polarity, there is a good chance that you have rotor winding damage also. If not you still may have to flash the rotor windings to ensure a correct polarized field. That involves hooking a battery for a couple of seconds to the rotor brushes (with correct polarity) with rotor brush wires disconnected. Only do this if there is no output voltage after you replace the control boards. Bad mistake :)

Check the pickup tube in the vehicle, the fuel pump is suspect. If you check the fuel pump pressure and it is ok, then try installing a test check valve between the fuel delivery hose to the generator. If it solves the problem the pump is losing it's prime internally, so replace the fuel pump.

Onan 4000 generator has no spark


If there is no spark, the ignition module may be bad, or the wiring to it. Have the module ohmed out. Also the magnetic trigger assembley that is on the rotor that sweeps past the ignition module maybe broken. If they check ok, suspect the control board
