24v Trolling motor plug

I have both batteries hooked up correctly for 24v system, when i check with the voltmeter at the plug, i show 12v. I am replacing the plug (male end). I only have 2 wires on my neg/pos, but the plug has 3 wires. Do you splice 2 into 1 in order to change from the 12v to 24v, or just go the typical red to red/blk to blk?

If you only have 12V at the socket, you don’t have the batteries wired in series to provide 24V. Post some pictures of your battery wiring and the plug & socket.

Hot runr guy is correct. This is what your battery wiring should look like where it says 24v would be your trolling motor plug

The other issue with the 3 wire plug is having the wires in the correct holes on the plug. I believe that positive goes in the #2 hole and negative in the #3 hole but check the instructions on the plug package to verify.

Thanks guys,Thats the exact diagram i used to check that i have them 24v, so my question now moves back to the female plug, that it may have never been wired correctly. It is the type with 4 wires and 4 male prongs inside that slide into the male plug from the Minn-Kota, which i noticed only has 2 live sockets, and 2 blanks.

Is this the boat-side socket you have? If so, what color wires are attached to what battery position?

Check the battery setup at the battery posts. If you have 24v going from the pos post on one battery to the neg post on the other battery, then you know the issue is with the wiring. not sure how you could lose 12v through wiring though… make sure your fuse is good? make sure nothing else is hooked up to that system? make sure your battery charger is connected correctly? Make sure your battery charger is off while checking voltage? Unplug your trolling motor and check battery voltage? Make sure the master switch is off? just some places to start troubleshooting.

Let’s stop the speculation on what you might have and what the solution might be. Add a picture of the type / manufacturer boat Socket and trolling motor plug.

Some do not require a jumper at the batteries. My jumper is in the socket. Many twist lock type sockets have 12v and 24v pins. The only lug is wired then to match which you need. So let’s see what you have

Agree with Randy here.

I’ll add one more check before you dig in too far. Pull the plug plate off for the female side. Then check what voltage is actually coming out the back side of the plug receptical to the 2 trolling motor wires. You may have 24 volts there.

Thanks, Thats it exactly, i removed the receptacle and found it wired for 12v, but my newer motor plug ( brand unknown/china) pins were not in the same location as the receptacle, tore them both out and ordered a matched set. The boat was newer but the motor was several years old hence the problem. The other owner obviously had a straight 12v motor or switchable setup somehow.
