Low voltage at jacks


I had the same low voltage problem at the jacks. It was very confusing. What tI found was one of the posts on the 50 amp circuit breaker was stripped so it wasnt making good contact. I replaced it, and problem was solved. But it was frustrating to find. Under no load it would display full 12 volts, under load, it would drop to 8.6.
