    I have a monarch hydraulics pump that runs my plow and it just starte acting up. The motor won't shut off without cutting the power to the pump. Any questions. The pump is new this year.

    The solenoid is probably sticking. Replace it.

    I agree the solenoid might be bad. Try taking the two little wires off the soleniod and see if that helps. If it does, something in the wiring is telling the pump to stay on. It could be the controller. Otherwise its your solenoid.

    if you use the wrong kind of solenoid this can happen, If it is not rated properly it can stick in the on position, and never turn off. Not sure what the requirements are for that pump, but we had some people running air compressors with starter solenoids and they wouldn't last at all because they are not rated for constant duty, just brief bursts.

    the sleinod is probably sticking but i suggest fixing it NOW! i have a story about my truck.. the pump decided to act up while i was in the shop and when i came out the truck was on fire so i lost a truck because i was going to wait until later to fix it so i suggest fixing it immediately!!!!!!!!!!
