    05 Chevy duramax with an x-blade. All the wires are brand new. Fisher solenoid that came with the plow burnt out last night after about10 hours of use. I replaced it and it happend 2 more times. About 2-3 hours on each. The 4th has been in it for about 5hrs now and no problems yet. The terminal that I run the power too has melted on 2 of them and the first one just spun out with really no effort when i put a wrench on it. Obviously its heating up for some reason and i dont know why. Could the alternator be going out and surging it with to many amps? I know GM has **** alternators. Any help would be great! Thanks!

    Check all of your connections and make sure the underhood plow ground goes directly to the battery.

    A bad plow motor drawing too many amps will melt solenoids.

    One use a heavier gauge wire from the Alt to the battery. Second use a trombetta bear solenoid for the plow (they are indestructable). Some minor mods will nee to happen to make it fit.
