    I have done the screwdriver magnet test on the coils and got magnetism. Power and grounds are correct to the coils. Still no pressure to the hoses. The pump was good last year, hasn't been used since then. Filter is clean, whole plow was bled, cleaned and fresh fluid added.

    No movement in any direction, fluid IS NOT making it from the reservoir past the hydraulic manifold to the hoses.

    Thoughts please. Could the pump just have **** the bed over the past year just sitting unused?

    Would all three solenoids be stuck? I could see if one or whatever, but not all three.

    No up either?
    Now can you try another controller for grinns first?

    Have you pulled the motor to look inside the pump? I thought I read that fisher had issues with the gears breaking off I know you said new, just wondering if you looked inside it yet

    Pump itself does not appear to be serviceable. The pump is NOT new, but it worked fine last year. Has been sitting unused since then. No reason I can think of for it to all of a sudden fail, but that still could be the case.

    It's not a standad 2 piece pump with the 2 gears inside?

    Perhaps it is exactly that. I haven't pulled it apart. Is that the only reason it would fail? broken gears?
