    check your battery cables.

    Check all the wires that lead from your plow control box to the power source as well as all wires that come from the plow setup to the power source. Some times if their is a cut in the wire or if the cable it self is exposed it drawn more power since its not a smooth flow its being interrupted.
    Good Luck with the trouble shooting!

    Could be the ground to the plow motor. Power going in could be having a hard time comming out.

    Is your idle too low or do you have a vacuum leak maybe?

    did you get the largest alternator known to man? If so the regulator is telling the high amp alternator to replace the juice all at once. a second battery would help solve that.

    the alternator is the biggest one i can get 105 amp. if i get the 130 amp i have to change brackets and to much work.. The cables under the hood are all good but i need to check the ones to the plow/.... i think there's bare wire showing on the power and ground at the pump.. i'm gonna heat shrink them and tape them... and try that....

    Could be a bad ground or the plow motor getting ready to crap out.

    Low Voltage

    You are drawing to much current from the battery and the voltage is dropping. At a low voltage the truck will stop running. Check battery, cables and the current draw the plow motor is using. A VOM will help you figure out your problem. See what the voltage on battery drops to when you turn on plow motor. There are many reasons the plow motor can draw large amounts of current. Motor failing, wrong fluid and bad wires. You need to check them all out. If you have any more problems there is a phone number to Meyers Snow Plows and during business hours they offer free tech support.

    It is your ground. I had the same thing with my dump body this year. Clean all your battery terminals, the connections on the pump and ground cables where they contact the truck frame

    The last one I did with that problem turned out to be the pos. terminal on the pump was bent and touching the housing of the pump motor. Straightened it up and put in new insulator. Good to go.
