Witing harness shows 25 amp fuse with 10 ga wire. Update shows 50 amp fuse with 6 ga wire. Another update shows 40 amp fuse with 10 ga wire. Mine doesn't work at all, blows fuse. Dealer can't figure out why!!!! Hoping we don't get any snow because I have a sander that won't work for more than 30 seconds without blowing a fuse!!!!
