Fisher MM2 angle problem

    My MM2 angles fine in one direction (3 sec), but slow in the other direction (7 sec). I replaced the cylinder, works the same. No corrosion on terminals. I suspect it is an angle control valve or the coil that operates it. The motor does not seem to run as fast when angling with the questionable side. Which of the 3 control valves activates the right side angle cylinder? Thanks.

    I would double/triple check and wiggle the harnesses truck to plow while somoene is operating plow to make sure your not chasing your tail when the problem is the connection.

    Everything works fine, except for slow angling to the left. Hence, my suspicion that it a control valve or the coil that operates it.

    Solenoids on plow pump have condensation in them heat the area with heat gut or hair dryer only. 2 valves for R/L, 1 valve U/D. Change your fluid.
