    Ive recently been experiencing some problems with my backblade running when i dont flip the switch. It likes to get stuck putting down pressure on the blade. It will run until i disconnect the ground or the hot from the battery. earlier this morning it got stuck down and ran the pump until i could get the ground off and the pump was smoking. Ihave no. 4 wire running from the battery to the bed of the truck as the hot wire and the pump is grounded to the box what could the problem be?????????????:dizzy:

    there must be a solenoid getting stuck open. Replace the solenoid wire going to the pump. Take a test light while some one is intermittently toggling the down switch. When they release it, the power should be cut going to the pump. Then remove the wire that comes from the down switch to the solenoid. Toggle down switch and make sure the power is cut. If it is your relay is bad.

    What kind of pull plow is it?

    I meant remove the wire going from the pump to the solenoid.
    I assume the solenoid is a standard automotive type?

    Post some pictures of it if u get time. Get some close ups of the pump to so I can get an idea of what we're working with.

    i say loose battery cable, making for low voltage. that will stick the solenoid. you should have a resetable 150 amp breaker at the battery just for this.
