    MinnKota Maxxum 80 cutting out, Stops working periodically, then starts again?

    Hi guys, my buddy purchased an almost brand new maxxum 80 off of a guy for $250... Everything seemed to work good at first. However, after my buddy ran the trolling motor for half a day his first tourney of the year, the TM would just stop working. He would let it sit for a couple days, and then it would work fine for a few hours then do the same thing. My buddy changed the breaker to a 60 amp, suspecting that was the problem. It made no difference at all...My buddy (not being very inclined mechanically) wouldn't do anything about it because the motor would all of a sudden start working for a few hours, and then once again cut out. I finally convinced him to drop the boat off at my house tonite so I can go through it and see if I can figure something out. My question is where should I start? I know it not tripping the breaker, I installed his plug myself, So I know thats not the problem...What else could it possibly be? loose wires in the head unit or foot pedal? I'm gonna assume the guy he purchased the TM from was having the same problems, and thats why he sold the TM so cheap.

    First, let me chastise you a little. You convinced your "buddy" to drop it off so you can look at it, and now you're wanting to know where to start???
    Now to answer your question. Start with the batteries, the follow the electrical path -- but do this when it isn't working, not while it is running good. You have something opening when it gets hot and will do no good to try and trace it while the motor is running properly. By the, how do you know it's not a plug problem, just because you installed it yourself. Is it a 4 wire or three wire plug? If a 4 wire, did you tighten all the screws, even the ones that doesn't have a wire plugged in?

    BTW, when you do get it to quit, turn the prop 1/4 turn and see if it will run. All voltage checks should be done with the motor plugged in and set to constant.

    Checked all of the connections, everything is good. plug is good, its getting juice all the way to the head, light comes on in the head but the prop won't turn? could it be a bad LU module?

    Could be, cept a maxxum don't have a module in the lower unit. The control board is in the foot pedal, so if you have juice to the head, you have gone past the foot pedal. Take the top off and look for burned connections in the head.

    You could still have a board problem, or a armature problem, or water in the lower unit, but I'm trying to get you to follow the wiring before starting to take stuff apart. With your obvious knowledge of trolling motors, if it comes to disassembling this motor should be taken/sent to a shop to prevent additional damage to a $1000.00 trolling motor. Even putting an additional $200.00 for parts and labor to a shop would bring your buddy out ahead.
