not sure if gonna be a common problem but my gauges quit. found the insulation worn off the wires to the speedo under the airbox. wore thru from rubbing on the bracket that holds the rubber airbox strap
my hand warmers were shorting out and making my screen blank on mine
turn them off it was good turn them on no screen or else all 8's took to polaris and they fixed them
talked to them and they gave me some places to troubleshoot. ended up taking my brothers 09 dragon 8 apart and used his gauge to find out the gauge was still the prob
changed the gauge and been good since
This also happened to me. There was a hand warmer recall which I believe they ended up changing out my cpu last winter. Never had a problem since. Maybe check into the recall.
