    is this a SEHP system or Insta-act system?

    If insta-act, check power to the three solenoids on the plow and also make sure your under hod solenoid is tripping like it should...

    http://fisherplows.com/publications.asp?cat=36 here are the two mechanics manuals....choose the one for your plow and check all your electical components with a test light or multimeter.

    I am having the same problem today. The plow wont go up or to the left. The motor is getting power, so I don't think its the solenoid. I think there is a bad connection between the wire harness hook ups from the truck to the plow. It is a MM2, just to let you know. Hopefully it can be fixed before we get this foot of snow tonight!

    If it won't raise or angle to the left then the S3 valve isn't opening...

    If you want to verify it, you can check the Lt blue wire on the S2 coil. I think your gonna find it isn't getting power due to a poor connection (as you already suspect).
