Wondering if anyone had re wired their cooling fan to a switch and if you have any tips to do so.

 

I thought about that, too. Decided to replace both the thermostat and the temperature sender switch (in the radiator). They were 30 y.o. and on their way out.

Bike runs cool now. Fan starts early and temp doesn't climb high like before.

Found this on another post:

"It's quite common for the radiator switch to fail, the tourmax replacement is over £40, and most of the cheap eBay alternatives switch the fan on at too low a temperature, so before you replace what appears to be a failed switch take the old one out and thoroughly clean the threads and mating face on the switch and radiator with scotchbrite or similar,to ensure a good electrical contact when fitted, it worked on mine today." Worth considering.

Cheers,

If you want to go the manual switch route, you will be replacing the duty of the thermo switch in the ground side. The fan should have fused power directly to it. The fan ground runs through the switch. Simply hook the fan's ground wire to your switch, then the switch to an actual ground on the bike.

 

Thank you guys! I've ordered a new radiator after seeing some damage. Ordered a new fan switch as well in case the radiator has a faulty one. My bike is missing a bunch of stuff on it, basically naked street fighter look right now. There is no gauges, wonder if that's a issue? Thinking about installing a aftermarket temp sensor somehow also

 

 

I put a switch in line years ago , basically it operates as normal in the off position , but gives me the ability to activate the fan early when I can see the temperature starting to climb .

 

Do you have any pics? Would love to see how this is done since my mechanical skills are questionable at best.

Also, what type of switch should I use? Where to mount it etc.
