Everything You Need to Know About 12v 24v Trolling Motor Wiring Diagram

If you are a fan of fishing, then you might be familiar with trolling motors. Trolling motors are electric motors that are used to move a fishing boat silently through the water. These motors are designed to help anglers maintain a steady speed and direction while fishing. However, connecting a trolling motor to your boat can be challenging, particularly with wiring.

What is a Trolling Motor Wiring Diagram?

A trolling motor wiring diagram is a blueprint or schematic that shows how the different components of a trolling motor should be connected. The components include the battery, the trolling motor, the charger, the circuit breaker, and the plug. The wiring diagram gives a clear picture of how each component should be wired.

Warning: If you are not an experienced electrician, it is advised to seek professional help when connecting your trolling motor.

The Difference Between a 12v and a 24v Trolling Motor

Before we delve into the wiring diagram, it is essential to understand the difference between a 12v and a 24v trolling motor. The difference is in the voltage that the motor runs on. A 12v trolling motor runs on a single 12-volt battery, while a 24v trolling motor runs on two 12-volt batteries connected in series.

What is the Advantage of Using a 24v Trolling Motor?

The advantage of using a 24v trolling motor is that it provides more power and speed than a 12v trolling motor. A 24v trolling motor also runs more efficiently and can last longer than a 12v trolling motor.

Trolling Motor Wiring Diagram for a 12v System

The following is a trolling motor wiring diagram for a 12v system:

Component Wire color
Battery (Positive) Red
Battery (Negative) Black
Motor (Positive) Red
Motor (Negative) Black
Circuit Breaker Yellow
Plug Two blue

Steps to Connect a 12v Trolling Motor

The following are the steps to connect a 12v trolling motor:

  • Connect the red wire on the battery to the red wire on the motor.
  • Connect the black wire on the battery to the black wire on the motor.
  • Connect the yellow wire on the circuit breaker to the red wire on the battery.
  • Connect the two blue wires on the plug to the positive and negative terminals on the battery.

Trolling Motor Wiring Diagram for a 24v System

The following is a trolling motor wiring diagram for a 24v system:

Component Wire color
Battery 1 (Positive) Red
Battery 1 (Negative) Black
Battery 2 (Positive) Red
Battery 2 (Negative) Black
Motor (Positive) Red
Motor (Negative) Black
Circuit Breaker Yellow
Plug Three wires (two red and one black)

Steps to Connect a 24v Trolling Motor

The following are the steps to connect a 24v trolling motor:

  • Connect the red wire on battery 1 to the red wire on the motor.
  • Connect the black wire on battery 1 to the negative terminal on battery 2.
  • Connect the red wire on battery 2 to the yellow wire on the circuit breaker.
  • Connect the black wire on battery 2 to the black wire on the motor.
  • Connect the yellow wire on the circuit breaker to the positive terminal on battery 1.
  • Connect the black wire on the plug to the negative terminal on battery 1.
  • Connect the two red wires on the plug to the positive terminals on both batteries.

Frequently Asked Questions (FAQ)

1. What is the maximum amperage that a trolling motor can draw?

The maximum amperage that a trolling motor can draw depends on the motor’s specifications. Most trolling motors draw between 15 and 60 amps.

2. Can I use one 24v battery instead of two 12v batteries for my trolling motor?

No, you cannot use one 24v battery instead of two 12v batteries for your trolling motor. A 24v trolling motor requires two 12v batteries to be connected in series.

3. What is the function of a circuit breaker in a trolling motor wiring diagram?

The function of a circuit breaker in a trolling motor wiring diagram is to protect the motor and other components from damage due to overloaded circuits.

4. Can I connect my trolling motor directly to my boat battery?

Yes, you can connect your trolling motor directly to your boat battery. However, it is recommended to use a circuit breaker in between to protect your motor and other components.

5. Can a 12v trolling motor be upgraded to a 24v trolling motor?

No, a 12v trolling motor cannot be upgraded to a 24v trolling motor. A 24v trolling motor requires two 12v batteries to be connected in series, which is not possible with a 12v motor.

Conclusion

Connecting a trolling motor to your boat can be challenging, but with a trolling motor wiring diagram, it can be an easy task. Whether you are using a 12v or a 24v trolling motor, make sure you follow the steps and connect the components correctly to avoid damage.
