OK fan isn't coming on and thanks to NJ traffic the thing needs to be... It looks like the fan always has juice the the temp switch grounds it out to operate... is there an easy way to test whether switch is bad, fan is bad or both? I already tested fuze with a meter...

Jump the two wires. If the fan goes on it tells you is there is continuity to the switch, the fan works and you can assume overheating in traffic indicates failed temp sensor switch. You can put a toggle on it and manually turn it on as a permanent or temporary repair.

How do I jump the wires? The juice goes into fan and comes out hardwired (no connector) and right to the switch... If I pull wire off temp sensor switch and ground the fan should kick over right?

All the sensors I have seen have two metal connector tangs to an internal snap disc that completes the circuit. If you have two hard wires, partially strip and jump across them to test for an inop switch.

Thanks will do tonight... I am pretty sure I can get to connector pretty easily. Tmep Sensor switch has one lead going to it. I am thinking Honda uses the threading to ground to the chasis through the radiator and complete circuit to save copper. But with that reasoning if I ground the lead to the sensor switch it should pull current through the fan... We shall see.

Looked up the diagram and you are correct. The plug ground goes to a strap ground and there is a single wire from your sensor meaning the snap disc completes the ground thru the shell.

Touch wire that goes from the fan to the temp switch to ground, fan should start.

Well I'll either be a little pissed or furious. Temp sensor is $51 and fan is $250 something... geez!

its amazing there isnt an AM part for the fan thats cheaper.

Mr. Cheap strikes again...

Here, while a little pricey, these might not require you give up beer for more than a month;
Switch
Cap
or
Toggle. An auto or tractor store should have rubber boots for toggles.
Also try Radio Schlock

OK jumped out the heat sensor and the fan came right on... thanks for all the help... now the big question... The bike was a 40th bday gift and they bought 5 year warranty... do I bring this back to the dealer lose it for a few days and hope they did it right or just eat the $50 and do it myself?
