Radiator Fan manual switch

Post by Shammon »



Can any one show me a photo or drawing on how to wire in a manual switch so I can switch on the radiator fan when required please,
I also want to keep the sensor. Existing temp gauge not reliable. 77 Gl1000. Thanks


Cover the basics and the technical will follow easily.

go to the sensor, and connect two wires to it, run them to a switch placed where you want it.

good to go.

The gauges were never spot on, more of a guesstimate.

The fuel gauge is the worst of all.

As an after thought, the water temperature sensor is very reliable.

What you might like to do, is to wire a light bulb across that switch you install, and IF it is burning, then the coolant temperature "is okay"... a green light if you will that all is fine.

a good way to test that thought, is to set the bike on the center stand, and let it idle and watch to see that the fans cycle on/off.

If the fans cycle on/off repeatedly, and you take a temperature reading with an IR gun, you will soon learn what is normal for your bike.

I keep an IR temperature gun in my saddle bags all the time, it gets used for a lot of things, mostly tires and bearing temps, and sometimes, the radiator.... but, I know that the fans cycle on/off on my bike, and I never get them another thought.
