Have you checked the 50 amp breaker in the coach battery box? It has a red or yellow button and red or yellow "flag" shows if it is tripped. You push the flag back in so it does not show to reset it. Could have happened when the power went out. In my Axis it is on the left hand side of the batter box, way in the back. Also check your store/use switch to make sure it did not trip. Same thing happened to me years ago and it was the breaker.
