1995 Generac GN 480 Q55-G
History- for a few years sometimes it would not put out electricity until after re-starting 2 to 4x. But then always ran fine and powered everything.
Was running great last week, today it started right up but shut off after 15 sec, restarted and it shut off again after 30 sec, 3rd time same thing. Each time it ran there was power at the microwave clock. The 4th time it stayed on for 3 minutes and there was power. Started the ac which worked perfectly for about 10 minutes when the generator stalled. I killed the ac switch and re-started the generator, it started right up and ran fine but NO POWER. Turned it off and on, still NO POWER. Gave up after 5 tries. Learned about the reverse drill quick fix, but no help. Checked and re-set all breakers, still no power. Help I was just about to sell the rig.
Have done some tests. Had 179 ohms at brushes.
Pulled the generator and examined the brushes. They were fine, 1 slip ring had black spot. Cleaned them up and now have 14.7 ohms testing at the rings. Putting all back together to re-do other tests.
