    The other day a went to drive home from work and when I went to lift my plow it would not lift up or move side to side so I checked the inline fuses and found one which was a 25 amp and blown so I replaced it with a 30 amp and I was now able to lift the plow and move it side to side but now I could not drop it down. What should I do as it now snowing out and we are expected to get a foot or more of snow. Please I need help your fellow plower Kurt.

    What kind of power unit does your diamond Use-
    On the plow or under the hood?

    It has under the hood with a belt driven hydraulic pump and a electronic joystick mounted on the stick shift. The truck is a 1994 F350 4x4 PSD 5speed .

    No the fuse is still good. I can lift the plow and I can move it side to side but I can't drop it.

    I would think that you have a poor electrical or physical connection in the valve that allows the blade to lower. Make sure you have voltage to this valve and check for proper operation.

    Check the bullet plugs in your harness, they're out near your valve manifold. I don't remember which one does what but see if one is loose or corroded. Like CTfireman said, check for voltage here also. If there is none, then go back to the SlickStick and be sure the plug is tight to it. If that's OK it's likely the stick is bad. I had one that wouldn't raise the plow.

    If you do have voltage at the valve solenoid and it won't release then the solenoid's bad.
