my dragon 600 blew 2 ecu's within a week of each other
it went like this for the second one. turn it on, runs for a little bit then spits a bunch of smoke from the electrical panel and dies. when i take the ecu off there's a burn mark on the bottom of the ecu and a small hole in it
I've eliminated the ecu as being the problem which is originally what i thought, being the reason why i just threw a new one on there, so what could be the problem that's causing the ecu to blow?
also if anyone knows where i could get another ecu (and the parts that are causing the problem) that would be helpful as i cant find any parts for this sled.

I’m surprised you haven’t had any replies yet. I’m no mechanic, but I’d suspect the stator or voltage regulator. Odds are pretty low of two ECUs failing in the same way.

You might want to start a topic in the appropriate Polaris section (the IQ chassis section) there are folks who really know their stuff that may be able to help more.
