Trolling Motor and Battery Questions.......

[Pat Curtis]

Alright....here's the deal....


I have a 16' Lund. The trolling motor is a MK Power Drive V2 55# trust. It's listed as 12v. When I bought the boat it was hooked up to 2 batteries. The 4 wires from the two batteries (2 pos 2 neg) lead to a female plug with 2 pos and 1 neg hooking into it (the boat manual says the boat itself is rigged for 12/24v with the 3 wire plug). Everything worked fine....


Until last fall my buddy took the boat on a fishing trip. He claimed the female plug was bad...so he cut the wires and wired the pos/neg from the trolling motor directly to pos/neg of 1 of the batteries....


So fast forward to today....after I made him buy new plugs and hook it all back up.....the trolling motor is running on what seems ? power from what it was last year...and appears to be only getting power from 1 battery (battery 1).


To describe what it looks like:

Battery 1: Orange positive to female plug. Black/Blue negative to Battery 2's negative.

Battery 2: Red positive to female plug. Solid black negative to female plug.


I checked the fuses and they all appear fine. Should I double check everything...or is there a wire crossed? I don't understand why my trolling motor is only running on what appears to be ? power? I also checked to see if there was any fishing line stuck around the prop..but it was clean.


If the pics don't show up, here are the links to Battery 1, Battery 2, and the backside of the female plug:

Re: Trolling Motor and Battery Questions.......

From what you are saying you are correct, you are only using one battery which is really all you need. You only need 12V for that motor. Disconnect the orange wire from the plug. Now connect that orange wire to the pos post of battery #2. That puts the 2 batteries in parallel. At the plug make sure the TM's red wire goes to red and its black wire goes to black. Double check all those crimped on lugs to be sure they are tight. You should install a 50 amp fuse or breaker on the red wire at or near the battery.
