O.K, Y'all,
I'm a better fisherman than I am an electrician (although there are those who'd argue that point), and I need help.

I just acquired a boat that came with two trolling motors, a 24v and a 36v. The onboard charger is wired to 3 batteries for the 36v motor, and a portable charger goes to the 3 remaining batteries (2 for the motor and 1 for the lights, radio, etc). I keep both chargers plugged in between fishing trips.

Got ready to take the boat out for the first time two days ago; onboard charger showed green on all banks, as did the portable charger. Hit the water, turned on the 24v motor (70 lb. thrust) and just barely moved the boat. Started running off the 36v, bow-mounted motor, and that one didn't do a whole lot better, but we were able to fish.

Next day was the same scenario, after the chargers being plugged in overnight. Before we even left the house, I hit the test button on the 24v Minkota, and the "recharge" light lit up.

I suspect I've got something wired wrong. I had to replace 3 of the 6 batteries on the boat before I even tried to use it. I thought I wired everything the way it was to start with, but the sub-par performance indicates otherwise.

I'd sure welcome any help.[/I]
