@MEXICOWANDERER All I had on when it was doing this was 3 of the 5 ceiling lights, so I'm not sure what could be overloading it. I had the breakers for the 120VAC stuff off(fridge, AC, microwave, etc.). I have had much more stuff running in this thing on the 12VDC system then this all at one time and it has never overloaded so I guess I have no idea what could be making it overload. Would it do this if the battery is just weak and can't keep up? Could it be that resettable breaker going out? I am puzzled at this point.
