What did you do to your Class C MH today???

I had a problem where my coach batteries would not work the 12 volt system in my Chateau by Four Winds. I replaced the two 12v batteries and no good. The coach worked fine when plugged in and when the generator was running but all else failed otherwise. checked the disconnect switch by the coach door it was A ok. Called a local dealer and low and behold there was a little circuit breaker under the drawer in the kitchen. Push in a little button and viola it all worked!!!! I was worried because we are leaving for a nice relaxing week and I didn't want to have to start the generator everytime I wanted to flush the toilet. I hope this helps if anyone else has such a problem.
