    hooked up a 24v trolling motor system a week ago, it worked great.

    this weekend I took everything in the console apart to clean it all up and make it look 'pretty'

    this time, the wire which puts the 2x12v in series(from positive to negative) started to smoke and the wire pretty much burnt up inside. this cable was a 6g, and after the first time it burnt up, I created a new one thinking it was a bad wire/connection...redid everything, and the same problem...wire smoking.


    what would cause the wire between the two batteries to fry like this? I am considering just dropping it off somewhere and having it looked over....

    You've completed a circuit. Used to do that for fun as a kid.
    Connect a positive to a negative and watch the wire melt.
    You have one wire connected to the wrong terminal.

    so we are good with the above right? (did not include breaker, but there is a 60 amp)

    now the problem must be somewhere elsee...

    It's correct for a 24V trolling motor with two batteries in series.

    This is to hook up two batteries in parallel.

    So I believe the problem was figured out.

    Both batteries positives are hooked onto a battery switch...so when the switch is on both--well, dead short. Right?

    The only thing I could think of was just to take battery 2+ off the switch. Tested it, worked fine, and fished Saturday.No fire or smoke
