Kohler 7CMZ21 Generator issues
Ok, my generator was running fine until 3 weeks ago. I've been on 15amp Shore Power for a few months. The volt meter on the battery with the converter running is showing 13.7 volts.
Problem 1:
I decided to test out some appliances on 50amp generator power. Three weeks ago when I started the generator up (with shore power unplugged), as soon as the transfer switch kicks over to the generator power I turned on the Main breaker, the converter breaker, and the GFI outlet breaker with the test button. The 110 volt outlets work and show okay with my tester. But when I plug in a power bar with surge protection (NOTHING PLUGGED INTO IT), it trips the GFI Outlet breaker every time! I've tried 2 different power bars. But when I plug in a 110 volt light, it works fine, no trips. Also the battery meter then shows 12.7 volts with the converter running.
I've been using the power bar on 15 amp shore power fine.
Problem 2 (and probably related to problem 1):
Today I started the generator, 3/4 tank of gas, oil is up, and the generator ran for 1 minute and quit. I start it back up again, 10 seconds later it quits. Battery meter showing 12.7 volts with converter running.
Could it be a bad transfer switch that the power is weak on the generator side? or maybe a grounding issue (shorting out)?
Any ideas?
Both 30 amp switches on the generator itself are both switched on. I checked the 30 amp fuse on the generator and it appears fine.
