MM1 Weird issues

    My brother has a MM1 V plow on his 94 F250.

    As soon as he does any functions the pump stays running even when the plow stops moving. If he screws with the plows moving it up/down, back/forth, side to side for about 10 min.

    he "thinks" it is the controller, but they are 400 and doesn't want to buy one and not have it work.

    Any ideas?

    Solenoid or pump motor sticking?

    I was thinking the motor solenoid could be sticking. I wish I had the truck in front of me, I am sure I could diagnose in in less than an hour

    When it does it unplug control. If it stops replace control, if it doesn't replace solenoid.
