    Plow goes up and down fine, when trying to turn left it goes up. Checked the S3 valve, springs is moving freely. The motor is running when attempting to turn and you can see the arms trying to go, but they only move a half inch or so. What would you suggest we look at next. Its a MM 1 with Insta-Act system.

    Thanks

    Well all fixed, replaced the S2 and S3 solenoid cartridge valves, all working now. Can someone tell me though was exactly the S1 and S2 do, just for reference. Thanks

    Lower = S1
    Angle right = S2
    Angle left = S2 & S3 together
    Raise = S3
