Great mod!
Along with removing the limiter it's one of the best things you can do for your ciblet.

After you mentioned this I did a quick search on 600rr.net for a fan switch mod and found this:Eclipze said:The ECU controls the relay via the orange/blue wire going to the relay. The ECU probably just uses an open collector driver to drive the relay, and expect you could just drive it in parallel with a switch. i.e. switch to ground should do it. It would be good to take some measurements with the multimeter just to be sure before doing it, but reasonably confident it would work a treat.
It's certainly not ground, as it's carrying 12V with the ignition on. I agree with your diagnosisEclipze said:Black/White
Is not ground. It looks to me like the Black/White is an ignition power feed from the ECU. Beside that, Honda have used a green based wire colour for all ground.
0V, sounds good so far.Black/Blue
It's black/blue, not blue/black that provides power to the fan. By the way, the other wire on the fan is a green one, connected to ground![]()
12V, yep.Blue/Orange
Constant power... always has power from battery.
12V, so your grounding idea sounds good so far...Green/Blue
Not blue/green... darn newbs. The ECU uses this to trigger the fan.
I'm completely and utterly shocked that when I ground green/blue, the fan comes on! Holy shit Tony, I had my doubts about you y'know...Aka... a wire from the Green/Blue to the switch, then the switch to ground somewhere (i.e. Frame bolt or a ground wire near where you want the switch).
That help?
coolant was a touch low but topped it up...although im going to pull the radiator off as its got a fair bit of muck in the fins...give it a good soaking and flush everything out.Aduro said:^ checked your coolant and oil levels first?
haha :lol: thanks heaps for checking in to this for me, think im gonna opt for the new switch ideaEclipze said:Had a look... it's possible, but not suprised you've had trouble with this one. That LED in the switch is really setup for when something is powered via the centre pin. Because you're switching the fan to ground, the LED cannot light up. You'd either have ground on both sides or the + and - backwards, which the LED can't use. So the solution is to pull apart the switch, pop the LED out, and then put an LED back in with the wires mounted around the other way. Not sure if you could use the same LED in there, but I believe it's just a common 3mm LED. Would be a good time to change colour if keen![]()
Then you have the Black/Brown going to the LED terminal, the center goes to the fans Blue wire, and the supply terminal to earth (green wire). The LED will come on whenever the fan is running, either by the switch in the on position, or if the thermoswitch has trigger.
You were probably hoping for a simplier solution hahaa... but unfortunately the LED in this switch is just the wrong way around for what you need.
An alternative would be to pick another switch, or use a plain switch and a separate LED.
