    Have a MM2, 3 plug, 4 port isolation.
    Motor was running but lifting and turning hard.
    Drained and cleaned reservoir, pick up screen was clogged.
    Also the single port valve had a bulge in it, so replaced.
    Testing with a battery, all valves move correctly.
    All motor, solenoid and battery terminals cleaned and re-tightened.
    Controller has power, and will light the red power light.
    As soon as I hit any of the 4 lift/turn directions, there is a "click" from the controller and the red light goes out.
    Have another controller from another truck, same thing.
    I do not here any noise from the solenoid when this is happening.
    Any thoughts for me?

    Thanks everyone.

    im guessing u didn't have a controller problem before u serviced it I believe in cause and affect id start by taking the solenoids cover off again son the insta act and c if anythings off/touching or configured wrong also make sure the pwr and grounds for batt cable plow side r tight

    Thanks NHresident, I appreciate your help.
    The controller light issue actually happened when I was lifting/turning after changing fluid for this season.
    I had figured there was more gunk in the res, so pulled that off and checked everything else to make sure it was clean. I was hoping that the power light going out meant there was an overload somewhere in the system, but really hoping it wasn't the motor.
    Long story short, I swapped out the solenoid and we are good to go.
    Thanks again!
