I was plowing snow using my winch to lift & lower my plow, for about an hour I was moving snow then out of nowhere my Grizz just flamed out, no power to the instrument cluster, nothing. Used a test light on battery & no power at the battery, let it sit for a day then put a battery charger on it in Start mode, turned on the key, I had power to the gauges, hit the starter button fired up. I took off the charger and tried it again & again and everytime it worked fine, and still works. The stator is new less than a year old, its a OEM stator. Battery is three yrs old & has never given me an indication that it is weak. Any help would be greatly appreciated.
