Looking for some help my 11 500ho battery was bad while using the winch the Battery box light came on. Checked Battery needed replacing so I replaced it but battery light still came on found it was overcharging then it was under charging, kept changing and then stopped charging so I replaced voltage/ecm regulator still have the same problem and the battery goes dead after 3 or 4 days WTF! The new Regulator is still overcharging so I stopped using the machine as I don’t want to wreck the new regulator (shows like 17 volts)currently cleaning all grounds and plan on putting in a ground wire on the Regulator. Any ideas why it’s doing this? second what would drain the battery down when the machine is off? Never had any issues with the machine before this, thought maybe I fried regulator using the winch with a bad battery installed. Then a new battery and volt regulator light still comes and goes so far when it comes on and I check the battery it shows 17 volts again, everything in the pod works as it should. My local ATV mechanic says it can’t be the Stator as they work or don’t I don’t know what else to look for any help would be appreciated as the snow is coming and I need to be able to plow with it He…lp!!!! I have heard some others that 11 sportsman 500ho’s that go into overcharge when reving high but I am not reving high at all when it starts.
