There were well over a million Sportsmans sold and most of them were good but they really messed up when they made them with the ECM that was too complicated.

 

I didn't notice this at first..Even I would have picked this one up at this price. 500 bucks,150 for an ecm, don't think you should be worried as this is a machine that's worth around $2800-$3000 if in decent shape. The ecm may last a long time but even if it doesn't you don't have one good reason not to smile..

 

That's the way I see it also. Even if I have to put another one in, it's a super easy repair. $150 isn't bad, wish it was a little cheaper for the reliability factor, but I'm happy.

 

......and it's dead again.
Made 3 passes around my house with it the first night. Parked it, went to start it this morning, and there is absolutely nothing again. Frustrating.
I should mention it also has a shutoff on the battery, that I also had turned off.

 

You have some other problem than an ecm itself sounds like.. This is where a wiring harness may have to come into play. Either that or spend hrs trying to track down what's causing the ecm to go south. Before I splurged on that I'd do a stator check from the manual. That may be the cause of the whole ecm problem.

 

Ok, I'll start there. I don't suppose you would happen to have a link for the stator check, would you?

Thank you sir.

 

Just wondering before I tear into this.
Do you think then, that the new ecm worked for that first ride, but the stator could have fried it in that short little ride?

 

That's kinda my thinking or you have a problem in the wiring harness or possibly even the ecm harness connector. The stator tests can help on this part. A general test is to check all the yellows leading from the stator into the ecm. Should be some resistance between each other with no yellow shorting to ground. Not entirely fool proof,but a start.The manual goes deeper into stator trouble shooting.
