Manually Controlling Radiator Fans
Gents/ladies, got a question about wiring up fans to turn on manually on my 08.
++ Disclaimer ++
My 08 track bike heat soaks a lot after coming off the track (regularly see 220+ with fans running wild, doesn't exceed 227 from what i can tell). On the track, it stays around 180s~190s, normal operating range. By no means do I think operating temp is the issue, but I would like to mitigate the heat soak so I can shut my bike off in peace.
++ Logistics ++
If I had a way to manually control the radiator fans, I would flip the switch as I am coming off the track in anticipation of the temp jumping. The bike currently does not have a highbeam/lowbeam switch stalk, so I figured I can use that for fan on/off switch.
The way I understand is that the ECU sends a 12v signal to the fan relay which turns the fans off. I would like to keep this automatic fan control setup just in case the bike shoots past 214F without me noticing.
My thought was to take the light switch, figure out which wires are for highbeam (since lowbeam is on all the time), then connect the highbeam wire directly to the ECU signal wire.
Logic behind wiring up highbeam switch to fan relay WHILE keeping the ECU signal intact is so that I can switch the fans on prematurely & manually, while keeping the automatic fan function for safety.
Has anyone done this before? Tried searching the forums right quick but no luck. Any input and/or correction of logic/knowledge is greatly appreciated!
