Fan trouble

Post by Hondaline »



For the last number of years, I've been running with a hard wired fan switch on my GL1000. I've decided to fix it properly by replacing the thermal switch. I put an aftermarket switch in without success. As far as I can tell, there can be no other problem so I bought a switch direct from Honda. The fan still doesn't start. I can't imagine what else it could be. The fan starts when I jump the plug. Any ideas would be welcome.

I'm going to ask the obvious....Are you sure the engine is getting hot enough to trigger the fan?

Temperature gauge is very high during the testing.

The temp gauge needs to be well over normal to trigger. If it gets 3/4 of the way to hot it should be running. Are you sure the grounds are solid?

A question first. Where did you get your aftermarket switch? Some switches are junk. If you purchased from Saber Cycle that could be your problem. There are switches that have temperature settings that are different from what is required on your Wing. That said, what was said previously is more likely the problem. Not letting the bike run long enough to get hot. You can test the switch in a pan of water with a meter and a temp gauge.
