Motorguide has been building trolling motors since the 1960s. These are small electric motors and a propeller that are fixed to a fisherman's boat at the bow or stern. This gives the angler the ability to precisely maneuver his craft into tight spots or to troll for game fish. Wiring a trolling motor to the boat's battery is a simple process, once you know where to connect the wires. A 24v system requires two 12v batteries that are connected together.

12-Volt Wiring

Run the black wire from the trolling motor to the boat battery and loosen the negative terminal with a wrench. Slide the black wire over the terminal and tighten it down.

Loosen the two terminals on the circuit breaker supplied with the trolling motor. Slide the red wire from the motor over one of the terminals and tighten it down.

Slide the red jumper wire, which is short section of conductor wire, over the other terminal on the circuit breaker and tighten it down.

Loosen the positive red terminal on the boat's battery. Slide the other end of the jumper wire over the terminal and tighten it down.

24-Volt Wiring

Repeat the process for connecting the black ground wire to the first boat battery. You will be using the negative terminal on one battery and the positive terminal on the second one to create the 24v system.

Loosen the two terminals on the circuit breaker supplied with the trolling motor. Slide the red wire from the motor over one of the terminals and tighten it down.

Loosen the positive terminal on the second battery.

Slide the red wire over the positive terminal on the second battery and tighten it down.

Confirm that the two batteries are connected with a jumper wire between one battery's ground terminal and the other battery's positive terminal. If they are not connected, you need to install a wire in this configuration to complete the circuit.

Items you will need

  • Wrench
  • 50 amp manual reset circuit breaker
  • Jumper wire

Warning

  • Be careful not to touch your wrench to the positive and negative battery terminals at the same time. This can lead to electrocution.
