    Doubtful. Check the coils for magnetism whenyou hit functions.

    Up - S3 magnetises
    Right - S2 magnetises
    Left - S2 and S3 magnetise
    Lower - S1 magnetises.

    It would help if you had someone to help you do this. I would also check the ground at the pump where the blk/brn wire attaches as it is your ground for the coils.

    Your on the right track. :waving:

    Check for magnetism FIRST. Then if you have it pull the valves.

    While pressing the controller functions check the respective valve coils for magnetism with a wrench or screwdriver first. If you have mag when you should then you just eliminated any controller, wiring, connections, or coil power/ground issues from the equation. Thus narrowing it down to a hydraulic issue.

    Then begin pulling the valves looking for the hydro issue if that indeed turns out to be the case..

    ok so take off the cover to where the cartriges are and put a screwdriver up to them and have someone move the control to the left or right up or down and if i have mag then the coils are jammed? could it also be the pump or motor

    Correct on the procedure.



    If the motor and pump are operating but it wont even angle then its more likely a function issue rather than a pump or motor issue. Does the motor sound strong? Does it sound like its dead heading against the relief as if none of the control valves are opening? These sounds can tell you alot if you know what to listen for and is all part of the diagnosis procedure.

    First things first you need to get a press gage on both of them as that's the life blood of initial diagnosis...just like when you go to the doctor whats the first thing he checks? Blood pressure. :D

    If both are capable of developing 1800 psi against the pump relief then you've got either a dieing motor or a bad connection or weak battery.

    These plows are on two different trucks I assume?

    Yes, or a power connection to it so be sure to check those as well before simply replace the motor.
