While at Maxton last weekend my generator just quit. It was raining to
hard to take a look at it and John was kind enough to let me plug into
his 30 buddy plug.
The generator motor would start and stay running as long as the start
switch was held in or the fuel solenoid held in.
It was producing no AC voltage on the gages and the fan wasn't running.
I found that on one of the brushes the little wire had broken off. Now
this had happened before not that long ago (less than a year). So I
took a closer look at the (slip rings?) part the brushes rub on. The
most forward ring, the one that the brush was broke on, is not a nice
round shape (looking at it from the end). It has a 1/8" deep grove worn
but only over approx. 1/3 of the circle. So now I think I know why I'm
going thru brushes. How big of a job is it to replace those rings? Are
they even replacable, or should I just buy brushes by the case?
