The motor on my Coleman Powermate Maxa 5000W generator runs fine. However, it does not generate any electric power. It has 2 push button breakers. There's only about 20 hours of use on it. I checked the brushes and they are okay.
I had the same problem and found that the terminal that connects the circuit board(containing the brushes) to the stator, had bad or blown out solder joints after the generator had been run under a very heavy load.resoldered and problem has not resurfaced.good as new.hope this helps..
The gensets on coleman generators are definately nothing to brag about but i would start by checking the windings and make sure the brushes have a clean armature to ride on
Take a 12 car battery and momentarily ark across the armature a couple times. You can generally do this on the front of the generator housing. Should be 2 contacts on front cover.
