Re: lund boat trolling motor plug
You are another victim of the 12/24 wiring scheme that boat manufacturers loved so much. There are a couple of ways to do this. An easy way, and a way to get you in trouble if you are electrically challenged. You are correct in that the batteries are not wired in series at the batteries. You have two separate 12 volt runs (one from each battery) up to the connector. 24 volts was obtained by a jumper inside the trolling motor plug on some motors or by the 12/24 selector switch on motors that could run from either 12 or 24 volts. Here is what you do.
1) Disconnect the orange wire from one battery, and the black wire from the other battery.
2) Tape the ends of those wires as they will ot be used. DON'T CUT THEM OFF.
3) Fabricate a jumper wire and connect it between the terminal that you disconnected the orange wire from, and the negative terminal on the battery that you disconnected the black wire from.
4) Your batteries are now in series and you will have 24 volts on the remaining red/black wire going up front.
5) Look at the receptacle and see which terminals the red and black wire (the 24 volt pair) are connected to.
6) Attach the trolling motor plug to your new motor wires so they match the 24 volt terminals on the receptacle.
7) DO NOT disconnect the orange and black at the receptacle.
8) Go fishing.
The next owner will thank you for not mucking up the original wiring.
