Hello, I went to start my 2012 Polaris Sportsman 500 today and had to jump battery ( new last month.) Ran for about 5 minutes. ATV them stalled and I had a ceramic/electrical smell. Jumped again and ran for about 15 minutes. Parked and went to start it again, dead cluster. No power, no lights nothing. Cables and connectors were checked. I'm really hoping its not the ECM. Any ideas? Thanks.
