    alternator is 5 years old 200AMP
    two batts. newer

    Never had this happen. Was stacking. I began to smell an electrical odor(not exactly a burning smell) was electrical though from the engine bay/front of truck. Checked it out. Couldn't pin point it. Check engine light came on. Hooked up basic code reader. No codes. Drove a few more minutes. Car lights began to dim. Parked it. Truck cuts off. Try to restart. Wouldn't start- like weak battery. Checked batt voltage. Voltage was 11.8 on both. Will charge them overnight and see what happens.

    Thoughts?

    Try to get you nose somewhere close to the alternator. See if it smells burn or sickly sweet. If it does. Remove it and take to an AutoZone or other parts store and have it checked.

    Time to give your plow and your battery wiring system a good looking over along with the solenoid.

    get the meter out...

    Don't you have a couple of cold days before the snow?

    Not saying it couldn't be the alt but having it happen
    While stacking leads my to a wire rubbing someplace?

    Of it was nice out nothing would be wrong....
    Your not alone....

    I was pretty aggressive stacking when it happened. Was in a rush. Will check wires 1st, then will take alt to b tested.

    That means the varnish on the windings were getting hot. Time to have it checked.

    Main wire from alt was toasted. Must have overheated while stacking with blower and lights on. Smelled like burnt marshmallows. Replaced with highest amp advance unit they sell. Used online advance site. Placed order and picked up at store, used 35 percent off online coupon from some website. Saved $55! Ordering this way will save you a fortune.

    Replaced outside and nearly froze to death. Works better than before now. Lifts quick.

    VERY lucky is didn't break while I was out in a storm in someone's drive in the middle of the night.

    If this occurred white stacking heavy snow and lifting the plow repeatedly to its max height, could the pump be faulty?

    When the 200 amp alternator was put on was the output wire replaced to handle the higher load? I think stock it only 136 amps.

    I added a welding wire output. The bolt that the wire was attached to literally disintegrated when I removed the alternator. The plastic shield that separates the output wire connector from the alt housing was cracked from heat. It is possible that arcing occurred.

    I added beefy grounds throughout the engine bay.
