Hi,

I have a 2005 Sportsman 500 that is overheating because the fan is not kicking on. I checked the fan blades and noticed they were not turning free because of some small pieces debris stuck between the radiator and fan blades. I took the fan assembly out of the ATV to clean it, and tried a bench test while I had the fan out. With a car battery on the bench, I put 12 volts to the blue wire, and grounded the black wire to the car battery. The fan motor will not turn on. Did I do the bench test correctly? I wanted to check with someone before ordering a new fan motor. Anything else I should troubleshoot to be sure the fan is bad? Thank you for you help.

Thank you

 

If it didn't work when you ran 12 volts through it, the only thing I can think of would be to reverse the polarity. If it doesn't turn one way of the other it's no good AFAIK. And you only need to post about a problem one time. No matter where you post it someone will see it.
