Did you have the use/store switch in use? The batteries will not charge if the use/store is in the store mode. There are two 50 or 100 amp breakers. One is located in the back left corner of the coach battery box under the stairs. The second is located on the left side of the engine compartment (when looking at it from the front grill). They have a button and a red or yellow flag or piece of plastic that sticks out from the breaker when it is tripped. Pushing the button deploys the flag so that you can see it. Physically pushing the flag back in closes the breaker so that current can flow from the batteries to the coach.
