Connecting a 24 volt trolling motor


Here’s my fishing boat wiring question:

My trolling motor is a 24 volt system. There are three wires that hook to the batteries. Red, black and orange.Motorguide trolling motor

Can you tell me which one goes where on the batteries? The orange has a 40 amp fuse that says “troll #2 batt”.



Hi Jason,

Here’s how you will want to set up your marine electrical:

  • Black goes to negative of battery #1.
  • Red goes to negative of battery #2.
  • Orange goes to positive of battery #2.

There should be a jumper wire that connects between battery #1 positive and battery #2 negative. This jumper wire should a 40 amp fuse in-line also.

Happy Boat Wiring,
