I have a 24 V trolling system that is connected to two separate batteries with four wires, each pair of wires carries 12 V to the receptacle. The wires are red and black and orange and black and white. The plug at the trolling motor has four prongs. The problem I have found is only one pair of wires is taking 12 V to the receptacle the other pair is not. The only explanation is the wire is broken somewhere underneath the floor because I have voltage to where it enters the floor but not where it comes back out to the trolling motor. My question is can I convert from a four wire system to a two wire system by connecting the batteries in series. If this is possible do I need to change plug and receptacle? What about the accessories I currently have running off of those batteries will they need to be removed or is there a way to wire those also?
Thanks for any help.
