i have a 2012 450 xc artic cat that's not getting a spark. the person I got it from hung the push button starter when he thought it was a good Idea to go though a lot of mud. so every time he hit the brake it would try to start. so the starter was bad I replace that and the Solenoid the solenoid was not bad I just replaced it. I found that the Coil, Ignition - Assembly had exploded so I replaced that still no spark. I was thinking the ECU or the stator any thoughts would help thanks.
