I've got a Minnkota 3 bank on board charging system that I am having a problem with. It is only charging on one bank, which happens to be the bank for the main engine. The other two banks are for my trolling motors and I am having problems with it. The indicator lights aren't coming on and the batteries aren't being charged. I have done a circuit test from the wires coming out of the charger all the way to the batteries and from that point it is fine. My question I guess is if two of the banks have gone bad, why is 1 still working? I would think that if one went bad they would all quit working. Everything was working fine until I unplugged it to vacuum the boat out. I plugged it back in after vacumming and thats when I noticed my problem. I was able to get the indicator lights to come on for a short time and then they stopped. I was thinking it was a ground problem, but not sure where to look.

I agree with hip hop. The In-fisherman crew has put together a great three book series that offers a lot of good information.
