    It works side to side and up normally, but wont go down, i checked all plugs, which i alway grease anyway, tried a different joystick and nothing. Checked power at the white wire (which i believe is the one that brings it down, correct me if I'm wrong please) on the solenoid and its got power and goes dead when joystick is pushed down.

    Bad solenoid?

    Should by white wire with yellow tracer. This is S1 valve. You can try swapping coil from another valve to see if it will go down. If that doesn't work you may need new S1 valve.

    i just bought one of the coils, only $17 I'm going to try and change it see if that will do. I was told to do the S1 does the down movement?

    Warning. Watch your feet when playing with the s1 when the plow is up.
