Replaced the wire harness that came in today, took off the generator and opened it up.
Commutator is really scored up from only an hour of use. When I cleaned and reconditioned it I polished it up with 600 grit and cleaned all the dust and grit out of it with a few shots of contact cleaner before I reassembled it. It was nice and shiney and smooth, now it looks really worn. Is that a sign of on of the coils being shorted?
The coils seem the correct resistance that I found in some over threads. Trying to measure any resistance to the case may be showing something that is bad? After cleaning the carbon and copper out my meter wasn't showing any path to ground, but now it briefly read 1 Mohm before going up to about 10 meg, so maybe there is an intermittent short when it warms up or jiggles, I started drilling the pole shoe screws out and will hopefully get those disassembled so it can unwrap the old insulation and see if there's any place that looks like it is shorting.
Armature still passes growler tests.
