    I have a 1995 2 wheel drive Gas F-Superduty with an 8' mm1 plow.

    First Question: The plow goes up and down fine but wont move left or right. I cleaned the filter and replaced the hyd. fluid yesterday and still wont move left or right. I replaced the controller last week. The other thing is that when I move the joystick left the plow goes up.
    I also purged the ram lines for the left and right.

    Second: When I do operate the controller my battery meter drops way down. It is a new battery from NAPA. Cranking amps at 0 degrees = 890, Cranking Amps at 32 degrees = 1040 (I think). Its the battery that was listed in the application book at NAPA. I also told them I was running a plow and they said it was the right one.

    Any help, opinions , advice would be greatly appreciated

    I have seen the tail of the hanging chain get bound between the piviot on a MM plow. It might be something to look at.

    check your grill connectors. you might need to spread the pins apart just a little bit. had this happen to a few of my westerns, pulled apart the connectors and spread the pins, worked fine after. good luck
