    Default Minn Kota Fortrex Troubleshoot

    I have about had it with the trolling motor system. I bought a boat used because it had a great motor (Yamaha VMax 150 HPDI) and it looked to be in good shape minus the clear coat. I have had so many issues out of the electric side of this thing. The control board will sometimes go in and out and you have to mess with the wiring on the back side of the panel at the console to get it back on. No biggie there jut need to replace some of those toggle switches. I completely rewired the whole trolling motor system to my Minn Kota Fortrex. It had a 4 wire system which I upgraded to a 2 wire 8 gauge system. I also updated the plug and receptacle to nip some of those issues in the bud. I also wired everything correctly for the 24 volt system. The trolling motor system is not running of the other batteries where the control panel is. Just these two batteries. It does have the circuit breaker but I can't figure out how to use a multimeter or anything else to find out if that is where I am losing power. I am tired of fooling with the whole thing. Need advice ASAP.

    Sorry I Was in a rush and not sure I explained in detail. Batteries are fully charged and new. Multimeter reads 12.8 or so in each. Itís wired for the 24 volt system and has worked the past 2-3 times after I completely rewired the system. The last time I went the whole thing was dead. Fooled with the foot control for a second and then it worked. And as soon as I put it back in the water dead again. Not sure if I did it correctly but the multimeter shows no power at the newly installed receptacle. If it gives a reading at the batteries it has to be the circuit breaker, receptacle, or the actual trolling motor correct? There should be nothing wrong with the receptacle as the wires are still firmly in contact and nothing is loose.

    A 12 volt test light will be a lot more helpful than a multi meter. The test light will add a load to the circuit that a multi meter will not. It with help track down the intermittent problems your are having with connections.

    I would check voltage at each connection until I found where I was losing voltage

    Great information. Tried to find one of the test lights at Home Depot and couldnít find one. Figured I needed a multimeter anyway and that would take way let me know if the batteries were the problem or not. Didnít know if the multimeter was capable of telling me if the connection at the circuit was bad or not.

    Yeah, that would be my guess.
    Circuit breaker bad possibly,
    Remove wires from outlet trolling motor wires are connected to. See if you have 24 volt to them. Reconnect the wires to receptacle and check there. If youíre good to that point it has to be the plug on motor or you can remove the plate under pedal and make sure everything connected well.
    Also might be switch under button on foot control. Is it round or half mood shaped on your unit.
    That will tell me what type switch it is.
    Chuck.

    On high voltage a multimeter is great. On 12 volts not so much. I bought a test light from an auto parts store. It does have a digital display that shows the voltage. Lights up red or green to tell you polarity. It surely helped me sort out my recent rewire of my boat. The Fluke meter I have just doesn't do a good job on low voltage

    Definitely getting power to and through the circuit breaker. Today it seemed like it got a little power to the motor but it quickly shut off before the propeller turned. Iím thinking itís the foot control and not the receptacle and plug.

    Is the button on the pedal half moon shaped or round.
