van battery draining with radio on rv battery
My 2005 e-350 van battery went dead while camping listening to radio using the radio selector switch on aux, a month ago. I thought separator, Sure Power 1315-200, was bad. I unhooked van battery from separator. A month later, I'm working inside van listening to radio on Aux. I even pull the fuse on house circuit and radio quits. I notice the house battery voltage isn't dropping even parked under cover. I go to start van and battery is too low to start. The van battery was still unhooked from separator. I remodeled entire interior this summer. I now have a very simple electrical system. No inverter. I have solar panels hooked to house battery. I marked wires on radio selector switch when I remodeled and have them installed from top: blue, black, red. I used van last winter before remodel and listened to radio for a week at a time without issues. Had good solar then though. Any idea what the heck is going on?
