    i just purchased a new to me 96 stroker with an 8' fisher, problem is is that the lights on the plow only work when i angle or lift the blade. noticed two broken pin on female plug and two broken wires on male plug. so until i can replace them i just cut the plugs and butt connected them until i can order new thinking it would solve the problem. NOT!!! i think its an MM2 cause it has three plugs and 1-4 iso mod. somebody please give me some insight before i set this thing on fire!!!

    when i lift or angle, the lights work. when i am not using the controller the lights are off and the truck lights go back on. and as far as the pins go im not sure as to which ones they were

    so when you "lift" the plow lights come on, when you stop, the lights go back to truck? sounds like something is not getting pwr or gnd. its seening pwer through the plow operation not where it should. check the main gnd for the plow from the truck. the iso mods. use the gnd to "pwr' everything up. see if that helps?

    well that is what i was thinking myself, that i was having a ground issue. i checked as many grounds as i could find with a test light, and everything appeared to be in order. ill try removing and cleaning. but i have to say that everything looks good, the guy i bought the truck from was good about cleaning all the terminals as far as i can tell cause all the power cables that i have removed have been cleaned. i appreciate your words of wisdom and see what happens

    bad ground on the light harness. using jumper cables provide ground to the light base and see what happens.

    Pin 11 (I believe) is the power for the lights- feeds off the marker light circuit to supply power to the relays to transfer power to the plow headlights. You're picking up power or ground from another circuit. Broken wires at the plugs will cause lots of issues- could be as simple as the wire flexing when the plow moves making contact in the circuit turning on the lights.

    Wiring diagrams are available on the fisher website.
