Trolling Motor Wiring Diagrams

While small and medium trolling motors use a single 12v marine battery, larger trolling motors use larger 24v and 36v systems, and require 2 or 3 marine batteries, accordingly. These larger motors and multiple batteries are wired in a series pattern, and optimally, the circuit breaker should be wired within 4" of your battery. Both the 24v and 36v trolling motor wiring diagrams are listed below along with the recommended circuit breaker. It is important to note you should never feed more voltage into a motor than what it is rated for (ie. never feed 24 volts into a 12v motor!).

Connecting Your Battery Charger

Onboard chargers are equipped with positive and negative leads for each battery. Simply wire each bank of the charger to each battery accordingly. 

 

Safety

To avoid shorts, it's always a good idea to keep the positive terminals covered with protective shields or proper electrical tape to prevent them from coming in contact with stray wiring, metal objects or other battery connections.
