Hello everyone. I am new to the site. Bought a 98 Grizzly 600 I did and found the service manual through here. Only seemed fitting to join. I did some checking on my own and found some contridicting results. The thermal switch activates the oil cooler fan. Its specs showed that to test it there is a starting resistance and as you heat it its resistance goes up. My fan is ok and wouldnt come on so in checking this out I found 5 volts to the thermal switch, which I thought was low, maybe should be 12, but the other wire was a ground so I jumped it and the fan works. So if the switch works in conjuntion with the control modual, why whould this work. And if it works why shell out doh for a new swith when I can put a manual switch in the circuit. Otherwise its a beast. Ive pulled logs with it. Ive pulled brush piles with it Ive pulled logs over slash ,logs , and brushpiles with it. Man this is fun. - Doug
