    I have a MT plow installed on a 2003 chevy 2500. The plow is 4 years old and I have had to replace the solenoid 4 times. Is there something that is causing them to go bad early.
    I think they should last more than a season.

    Most common cause of constant solenoid failure after poor, dirty, loose connections is the operator.

    Allowing the pump to run against the pressure reliefs draws excessive amperage and shortens the life of pumps, motors and 12volt MS.

    If you are replacing them with a regular automotive solenoid then that is part of the problem too. The solenoid is a heavy duty unit.
    I am wondering about the stacking thing too??
    Raising the blade while stacking isn't any harder on the solenoid then raising the blade when you are done with a pass.

    I think what is almost being said is that when the blade has reached it's furthest point of travel and you finger is mashing down the button because you want more of that angle you are running the pump against itself and the solenoid has a bunch of amps running through it and that will trash it faster than anything. :eek:

    that's the plowing 101 I got, if I am wrong somebody will correct it.

    if you are stacking heavy snow lift the blade up like it is a front end loader then it hast to work extra hard and can cause the relay to go

    It's all about prolonged high amperage draw
