8611 problem

    Our 8611 (old style) is having a problem lowering. The motor runs fine and all other functions work well but it won't disengage from the truck. It was working periodically but stopped completely today and will not lower at all. I was doing some reading on this and similar problems and the solution seems to be the coils (S5 S8).

    My questions are..

    Can I use my coils from my 810 to at least temporarily fix the plow before buying coils and finding out its not the problem?

    Do the wires attached to the coils need to be cut or do they pop off the coil it self?

    Thanks in advance.

    Does the float light come on when you toggle and hold it to full lower? I would have to say one of two things.

    1) Switch out the dieode (that can cross over from 8611 to 810.

    2) check the Float coil.

    I do think the coil is the same part the pins (valves) change. You have to CUT the wire for the ground the + end is a pin connector and you have use a specail tool to remove/replace that pin. At least that is what Eric does I am sure their might be another way.

    Also you might be able to inspect the coil for blistering. That is a sign of overheating. This happen often when the plow controller is left on and the plow is lowered and parked but NOT in float. Ask me how I know....


    Hope that works.

    Thanks Ron. Yes the float does work on the control box. I did think there was "special tool" for this but was hoping not to have to get in to that.
    Hope that works.

    Not an expensive tool. Looks like a dental pick. You might be able to use something else. It is the pin at the plug side of all the coils. The ground side all goes to that same bolt.

    Goes to show you even how little you think you know about me. It is just sad.

    At any rate Thanks for the back handed comment.

    Best, Ron G.

    Your welcome Ron! :waving: Still in shock...



    JD, I had an older 810 (I believe it's an '01, old 4-hose model) get stuck up last year, turned out the wire for the float coil had a bad connection due to corrosion. I've also heard of problems with a diode on the plow that would cause this, but I'm not sure enough on where it is...
