I bought a used 17' Nitro with a Motorguide 750 Brute, 12/24 volt trolling motor that was wired 12 volt. I've searched the threads and was grateful for the information on how to wire a 3 wire, 24 volt system. My question though, is there are only two wires from the foot controll to the 4 prong plug which is connected to the three wires going to the batteries. It looks to me like the previous owner robbed the two wire connection from a previous 12 volt trolling motor. Now, the foot controll has a 12/24 volt switch, but only has two wires connected to it (one hot, and one going to the motor). By disconnecting the hot wire, (now 24 volt) from the 12 volt terminal and connecting it to the 24 volt terminal, the motor works, but seems to run extra fast. My concern is, is there a separate circuit that should be connected to when using the 24 volt system as opposed to the 12 volt system. I haven't had it in the water yet to test it under a load, because I'm afraid of burning up the motor. Any help would be greatly appreciated.
