Hi ,Don I have the same coach as you except in the Itasca model the control panel is voltage sensitive if it's low it protects itself my chassie battery gave up in a Costco parking lot luckly,had to use battery boost to start and move away from the gas pumps, replaced battery and got back to the camp ground we were staying at went to lower the jacks and nothing panel dark, I disconnected both harness's on the back of the panel waited a few minutes plugged back in and back to normal.welcome to the forum there are so many helpful people good luck.
