Need help with Electrical problem

I've had similar problems, (actually every season). In my case it is either a bad ground connection at the battery or a small 12v circuit breaker that gets tripped whenever I put the batteries back in the coach or sometimes it has something to do with plugging in and the 12v disconnect. Just find the breaker and push the tiny reset. Mine is located in a metal closed electrical box inside one of my compartments.
