A friend of mine replaced the batteries in his Lowe Tahiti Deck boat. It is a 24 volt system after replacing the batteries the trolling motor was dead. We checked the batteries and fuses all were good. We suspected the the batteries weren't connected properly and and switched the ground leads on the battery. The motor worked briefly acting like it was a near dead battery but that wasn't the case.
There are only 2 wires going to the trolling motor from the back of the boat. The connector that the the cable going to the front has red/blue tracer, black blue tracer, Red and black on the battery side I thought maybe the black wires were tied together at the connector but when I ohmed them out I only read a short one way. So my guess here must be an isolation circuit in the connecter and that has failed so no 24 volts to the motor.
We reconnected the batteries like they were in a photo the owner took before disconnecting them. Any thoughts or information would be appreciated.
