Thread: 12/24v trolling motor

I have a 12/24 volt trolling motor. The 12/24 switch is on the trolling motor. My question is how to wire it?? I have 2 12v deep cycle trolling batteries.

What Type Plug Do You Have To Wire It With? In Most Cases You Have 3 Wires. A Black , White, Red. The Black And The White Normally Make 12 Volts. The Black And The Red Make 24 Volts. If You Have It Wired With A Jumper On The Batteries. Put The White On The Positive Terminal Of Battery 1 The Black On The Negative Terminal Of Battery 1. Have A Jumper On The Negative Terminal Of Battery 1 That Goes To The Positive Terminal Of Battery 2 . Then The Red Goes To The Negative Terminal Of Battery 2. That Should Give You 12 Volts Off Battery 1 When You Switch The Switch To 24 Volts It Should Pull Off The Other Battery And Give You 24 Volts. I Hope This Helps.

Some of those older 12/24 systems are 4 wire. Need to know exactly what you have.

I have 3 wires..Plus what appears to be the jumper wire. Red, Black, and a black&white along with the jumper..

I just changed my trolling motor from 12 volt to 24. Can I use my old 2 wire pluge for my 24 volt motor?

Yes it is a 24 volt. I had a 12 volt and i'm changing it out to a 24volt that I just bought. So the old 2 wire pluge on my 12 volt motor will work for my 24 volt?

Yes you can use the old plug. But what size is the new motor, how far away are the batteries and what size wire is going to them?

You will be in good shape. Don't forget to install a 50 amp fsue or circuit breaker.
