    Hello,
    I have a 1997 Ford F250HD with the Powerstoke diesel, and a Fisher MM2 8'HD plow. My problem is if I park the truck with the plow attached for more than a couple of days, The batteries barely have enough power to start the truck.Any longer I have to jump it, and I do turn off the control inside. I have two optima yellow top deep cycle batteries and a 200 amp alt. Has anyone had this problem, any ideas would be greatly appreciated.ussmileyflag

    Make sure the red wire in the cab goes to a switched ignition source. If you have to turn the control off after removing the key it is not hooked up correctly. Even turning the control off doesn't kill power to the module.

    That makes sense, The plow will still work with the key off. Thanks.

    You said you turn off the controller tho. What happens if you unplug the plow? Does the trk still go dead

    If control red wire is hooked to constant power source the module will be constantly powered up even if the control is turned off. This will drain the batteries.

    Turn your headlights on then turn the control off. Plow lights will stay on. Atleast this my understanding of it.

    I thought that was b/c the gnd wire completing the circuit telling the module the plow was hooked up?
