    Check your electrical connections, starting at the battery cables. Do you have a voltmeter to confirm the alternator is charging?

    To start, clean both ends of both battery cables. Also clean the positive wire coming off the alternator.
    With the truck off, the voltage on the battery should be about 12.6 Volts. When the truck is running, it should increase up to 14 Volts or so.

    well. just jumpstarted it and all ran fine. disconnected cables and it still ran. disconnected the negative cable for battery and still ran. checked voltage at the battery while it was running and it was 14.8 volts. went to lift plow and motor died. went to restart and battery dead.

    Take your battery to autozone and have them test it - if you're getting a charge from the alternator, it could be your battery is bad.

    I'm assuming your truck dies with the plow on only. Still could be a dead battery cell. If the truck is doing this without the plow why is it not at thr dealer being worked on?

    Clean the plow connections too.
    I am betting a bad battery tho.

    I'm betting battery to. If the battery check out ok slim chance lose pos. wire on the starter or solenoid. you have 14 volts when the truck is running?

    You probably have multiple issues. The battery may be weak or not being charged. The starter may be toast or the solenoids. They may not turn do to heating from the exhaust. The plow pump motor may be pulling way too many amps and the voltage drop kills the engine. Clean and put dielectric grease on all the connections.Clean and grease all the ground connections on your engine,to frame and plow pump. Charge your battery at home and have it tested at AutoZone etc. Plow trucks have unusual and multiple problems at times. It's just a fact of nature with them.

    well... got it fixed, but had 2 issues. first was that it WAS the battery. wasnt able to get it load tested yet so i put another one in and worked fine. other issue was i could get the blade to go left and right but not up and down. also if i tried to go down it felt like it was jamming. checked the cable where it goes into the plow and it was full of water. melted the water and bam... plowing again... thx for help all and hope this helps another person if they need it
