Tried starting coach after being parked for a couple of weeks while hooked up to 50A shore power. Got a low voltage indicator so I replaced the chassis batteries. Coach started and after I let it run for a bit I shut it down and started to get a low voltage indicator on the house batteries. It eventually dropped to the point where my control panel shut off and we had no 12 volt power. Prior to changing the chassis batteries the house batterries all tested at 6.5 volts and were maintaining a 13.4 charge. When I start the coach back up the charge comes up immediately but then drops again when I shut it down. Do I have a house battery issue or is there some other electrical issue going on?
