Out riding the other day, and sled abruptly dies like I hit the kill switch. Wouldn't start back up. Tried new plugs and it started right up. So closed the hood and got my gear back on. Was idling fine and then just shut off again. This time there was smoke rolling out from under hood. Smoke was coming from ecu, and smelled like an electrical fire. Got towed back by a ski-doo. Sled is '09 Dragon 800 w/2300 miles. first failure of any kind. Has any one had this kind of experience?? dealer says I need to replace voltage regulator and ecu, and should be good to go again.
