Question:
I have Item #3802346 and the charging light has been staying on after disconnecting the trailer and I was wondering if it is normal for charging light to stay on while trailer is disconnected? Since I have a battery running my winch, will it drain that battery? Will this “charging” overcharge the breakaway switch battery?

Expert Reply:
The light might stay on briefly on your # 3802346 but it shouldn't be on for a prolonged period of time. What it sounds like is that the breakaway battery is pulling power from your trailer battery/winch battery. It won't overcharge it so for now it is fine but I don't recommend leaving it that way.
All you need to do to prevent this is add in the Roadmaster Hy-Power Diode # RM-790 between your breakaway and your other 12V battery. This allows the electrical current to flow in only one direction so it won't be charging off of the other battery while disconnected.
