Run the black and red wires from the trolling motor to the boat's three batteries. Align the batteries in a row to make it easier to wire them correctly.
Loosen the terminals on the top of each battery with a wrench. Insert the black wire from the trolling motor in the first battery's negative black terminal and tighten it down.
Cut a section of wire to run from the positive red terminal on the first battery to the negative black terminal on the second battery. Strip 1/2 inch of insulation off both ends of the wire. Push ring connectors onto both ends of the wire and secure them by compressing them with pliers.
Fasten one end of the wire to the positive terminal on the first battery and the other end to the negative terminal on the second battery.
Cut, strip and connect ring terminals to another section of wire. Connect the wire to the positive terminal on the second battery and the negative terminal on the third battery.
Fasten the red wire from the trolling motor to the third battery's red positive terminal and tighten it down.
