It’s just a short somewhere. If I’m not mistaken the one I found was linked the the slav receptacle. Also check the ground on the back of the engine.

Seems like a short or a resistor that&#39;s not resisting.

Pull the FM for the generator, and follow the troubleshooting steps. If you are not a 91D, you are not authorized to do anything about the 10 level maintenance, and should get it into the 3rd shop.

Some generators put out noisy power with spikes and overvoltages.

I would suspect it is the voltage regulator has gone bad.

Check all wringing on The charging circuit to ensure the are no bare wires exposed or shorted across the ground.
