My temperature light comes on when I am going slow. When we are riding fast enough air is hitting the radiator the it normally stays cool. The fan never comes on but if you hook up the fan directly to the battery it runs fine. My dealer has replaced the circuit breaker and the thermo switch but the light still comes after riding for 15 to 20 minutes. If I stop and let it sit the light stays off for a little while then comes back on. I am not boiling over. Any ideas??

Thanks
