Fan Runs
Noticed lately that even when started cold, my fan runs. In fact, I believe it runs all the time. I just travelled over 250 miles on a trip and never went over 2 bars on my temp gauge, so it's not overheating, but the fan runs continuously. Suggestions?

Check out the wire coming from the fan to the heat sensor switch, it probably has been pinched and is grounding out. Otherwise the sensing switch would need replacing.

Many of us have also added a manual bypass switch to that wire and then to ground so that we can turn on the fan manually during parade mode.

Most common quote from a cager after killing a motorcyclist.

"I never saw him" instead of "I never looked for him".

unusual but the fanswitch might have gone bad in the on position

just replaced the one in my sei with one from a 93 Geo,works fine so far,normally runs 3 bars,fanswitch turns on at 4 bars just prior to turning on the 5th and turns off about 20 secs later

still have the bypass switch installed as a precaution

When the sensor went on my GL1200A, and the fan continuously ran, I assumed it was engineered to "fail" in that manner. I also added an off switch. However, when the sensor failed on my 1985 VF700S, the fan won't come on. So much for the "engineering" theory.
