Walt, you need to be + to + and - to - on those batteries to have 12 vdc. If you go + to - you will get 24vdc. The other thing you can do to verify is to take a multi meter and go from gnd to the hot wire going to your trolling motor and see what you have. Get with me tomorrow at work and let's scratch it out.
