The ride is an 04 Sportsman 500. I tried to wire a fan switch in so that I can run the rad fan all the time. I did this with my Ranger 400 and it worked awesome. Engine temps never get over 175 regardless of type of riding or ambient temps. When I turn on the fan switch (which is tied in to the main power wire from the power distrubution box), The fan comes on but the engine hot light and check engine light both start flashing. So when the fan is manually on I loose my only indication of how hot the engine is. How can I turn the fan on and keep the warning indicators off?
