    Just bought my 860 SW 2 months ago and on my first plow job last night the motor just started smoking. After a night of hell getting other guys to plow my lots, I went to the dealer and they took the motor apart and the bearings were shot. I hope this isnt a prob with blizzard motors. I buy new equipment so I can stay dependable and this crap happens. They are replacing it tomorrow so hopefully I dont have to deal with this again. Think I am going to look for a backup motor though. Just had to vent.

    Ok from another thread somewhere else I'll tell you what to look for if you cooked a motor.

    Alternator is probably too small 165 amp is recommended for plowing use as you truck suck up about 90-98 amps just to run with lights and heater going before you add a rotator light if your not running a strobe.

    Battery stock is too small usually only a 750 CCA. Upgrade to a heavy duty 1000CA 850 CCA battery. Feed lead from alternator to battery is under sized.

    IF the plow is not GROUNDED to the battery you will have problems.

    Plow wiring on the plow GROUNDED to the block between motor and Reservoir.

    Check these first. This info is Coming from lots of installs and fixing truck charging issues on all trucks and plow brands. J

    Jason, did you ever add a second battery?

    No. I did not add a second battery. Are these issues that would cause the bearing to get destroyed. My lights do dim quite a bit when I use the plow. I just bought a new battery, but cant remember what CCA is was. I know it was more expensive than all the other ones. I have the plow package on my truck, so that should be a bigger alternator they said. Oh, and I know I worded my original posts wierd, but the plow has been used many times in last two months, it was just the first plow job of the night when it broke.

    In the years I have owned Blizzards I have only toasted two motors.

    BOTH were a result of either failing Alt. or batteries. I run all dual Battery charging systems. In the dual Alt's, dual Battery Trucks I have seen no issues. Replaced the both batteries on the one truck and upgrades the single alt on the other truck and have not toasted a motor since.

    We purchased 2 8611 full size plows this year and have been plagued since the get-go with issues. So far, on one plow alone, we've had to replace three motors - two burned out, one blown seal. Our truck side wiring harness was causing our fuse problems. Oh, we almost caught the plow controller on fire as well. All said, we've had about 200cm (6' feet) of snow this season and we've managed one full 6" event with both working throughout.
    We now have bad welds on both 'A' frames supposedly busted because we hit something?? - and it's causing uneven cutting edge wear only on one plow??? Across the 8' center, we're 1" depth difference. Paint is another story.

    All that said, when these puppies are on the ground plowing, there's probably nothing better out there. Keeping on the ground, and lifting for transport to another site, well........
