    I've got the 3 plug set up. Plow is 5 years old, but electrical in the truck is only 1 year old. Just hooked it up for the first time and have lights, but no hydraulics. There is the clicking sound when you try to operate it like it's telling the plow to move, but the plow is not moving.

    Fluid was changed end of last season and is full, I checked it this morning. I am assuming the problem is at the pump on the plow frame, but how would I start crossing potential problems off the list. The problem could be the truck or the plow as far as I know.

    Thanks for any insight you can offer.

    Use a set of jumper cables and hot wire across the motor solenoid briefly. If the motor runs your solenoid is defective. If it still doesn't run its time to start checking the cable connections between the battery and the plow. Be sure all cables are connected.

    95% the selenoid under your hood is bad. $25 part, and a 10 min fix. If not that, check all your negative and positive battery connections as well as on the plow itself. Make sure no nuts are loose, and that the plow is receiving postive power and good negative grounds. Your problem will be solved.

    This was my first thought but didn't want to screw it up. Connect the battery directly to the pump you mean?

    Start by just connecting across the underhood solenoid first...by simply connecting the two larger posts together onthe solenoid briefly with one of the jumper cables. If the motor runs, then you'll know it's a solenoid issue. If it still doesn't run, then jump directly from the battery to the motor itself using both the ground and positive jumpers.

    Really? Well whatever it takes. I'm just glad it's now and not January with 6" of snow in the forecast.
