A Way to Test the Fan Switch??

It's about a thousand degrees out on the way home. Sitting in traffic and temp is heading past the half way mark. Lean over and look and the fan is not moving.

Thankfully things sped up and I was able to cool it down.

Got home removed fan lead from switch and grounded it and the fan came right on. So, most likely problem is the switch. The connectors on both the wire and the switch are pretty corroded, so I will clean them up first.

I have another radiator with a switch in it kicking around. Before I drain my radiator to replace the probable bad switch with one of unknown health, I thought I would ask if anyone knows how to test the switch.

Thanks,

Jon

You can check for continuity on the switch, Start the bike let it get warm and check again.
When the switch gets warm continuity will allow groung to go through the switch.
If you have the switch out you can use hot water in a pan and do the same.

If your switch checks out good, then the problem is the relay in the junction box. I have the same problem. The relays are the back of the junction box and have a rubber backing covering them. There is no way to remove the rubber backing without partially ruining it but I have heard of some people repairing the relay. The headlight and starter relay are also in there as well.
Some people have simply bypassed the junction box and installed a manual switch as a new junction box is not cheap, $177 at bike bandit. Ayers website seems down for now? Hope yours is just the main switch at the radiator.
