Have winterized my 17B. It's plugged into AC power, .... When I put the battery switch "down", the trailer lights go out. Which way should the switch be? What have I set up wrong? I thought on AC power, nothing draws on the batteries?![]()
Just reread your post..
If you are plugged into AC, shouldn't the lights stay on even when the battery switch is down (disconnect position) ? Can someone else confirm this?
I am thinking that your DC charging system is not working, and leaving the battery connected is slowly draining it. I would think that the converter should keep your DC system at 13.6 or 13.1 volts while plugged in.
If I was in your situation, I would run out and get a battery charger/minder, and get your battery recharged while disconnected right away before finding the problem.
