Fan not working – 08 Sportsman 500

Hello once again,

I’m back with a new issue, and really, I believe I just need help locating the components on the bike.

On Monday I was plowing for the first time this year, and the bike overheated before I finished my driveway; the overheating has happened before, but not so soon. I checked, and noticed the fan wasn’t spinning at all.

Did some research online, and found a thread related to a 2011; experienced similar issues, and traced it back to a circuit breaker (SSCB) that needed to be replaced. On the 2011, he said it was near the battery, under the airbox. Does anyone know where this would be on a 2008?

From the service manual, I tried to do some of the trouble shooting, but the draw test can’t be done because the fan won’t come on, even with the heat sensor disconnected. I plugged the fan directly into a 12V, and it spun without issue.

At this point, from what little I know, I’m guessing the issue is in the relay or the SSCB? I think I know where the relay is, and I’ve pulled it to look for corrosion (none). I suspect there is a way to test it was a meter; if anyone knows that process, it would also help.

I took some photos of what I could locate to confirm I’m looking at the right parts. One is of the heat sensor (I think, please confirm). The other is of a SSCB, its located close to the ECU and relays, up front. Not sure what this one is for.

I grabbed a photo of two SSCB’s that are wired into a red line coming directly from the battery, towards the back of the bike. Well I thought I took the photo.. What would these be for?

There is a winch on the bike (probably a given because I was plowing). It also has the 3-light mod and reverse override mod, but I don’t believe either of those extend beyond the headlight pod.

Any help is greatly appreciated – hopefully I can get this sorted out before the next snow fall!
