Been scanning forums on this issue. Noticed recently that the cooling fan has not been cycling on like it once did. My oil temp light is not coming on (it is working in the test mode when you turn the key switch on). The ATV does not get submerged in mud or water. It primarily ride fire roads and our local gravel roads. I do plow with it and gave it a workout this winter. The cooling fan fuse is good, there is nothing in the fan and the blades turn freely by hand. I assume it is either the fan switch or the fan. Can someone describe the procedure for applying 12V directly to the fan to test it. Do you disconnect the blue connector between the fan switch and fan and do it there? If so do you need to connect + and - to the pins in the connector or just +, I am not sure how to do this and do not want to fry the fan if it is good. Any advice on how to test the fan is appreciated.
