Cannot start MH from chassis battery.
I own a 2004 THOR 30Q, ford chassis, intellitec battery control center. The trouble I am having is I couldn't start the MH today. I used the aux battery's to start it and it fired right up. I plug in to shore power and the chassis side fires right up. The the chassis battery test out at 12.4volt ..
Can this be a bad chassis switch or something else. The chassis power is intermittent and not enough to start the engine..
Any help would be appreciated.
