    Just hooked up a new blade on my truck. Fisher mm2 w/insta-act pump set up with 2 plugs for the older truck. Raise, turns left and right no problem, But will not lower. any one else have this problem?

    Start with checking the S1 valve/coil assembly for magnetism. The S1 is the valve thats responsible for lowering the plow.

    You can go to Fisher website and download the Mechanics manual for your Insta-act pump to familiarize yourself with the valve/coil layout.
