My house batteries were replaced three years ago. I keep my coach on a pad next to my house, plugged in. We keep stuff in the refer because we try to go out once a month. A couple months ago I took it in for service and the house batteries went dead after a day or two. I checked the batteries and could see no water in them. Filled them both with distillled water. Batteries took a charge. My question is should I leave the coach plugged in. I thought the batteries would take a charge and then taper off. Also, the aux switch in the stairwell doesn't seem to do anything. My manual says it disconnects the house batteries from the 12 volt system so they don't drain down but do they become disconnected from the system that charges them? While my coach was setting on the pad plugged in my batteries got very hot and boiled out the water. I am confused. This weekend trip I had to run the generator a lot because the batteries just wouldn't hold a charge.
