my fan seems to have packed up

YMFB · 14-Jul-2009, 23:08

I have removed the LHS fairing, disconnected the fan at the big white connector and applied 12 v directly from the aux socket and the fan works, so it isnt that.

Where is the relay than switches the fan on/off located ?

Or should I be looking for a thermostat, if so whereabouts.

Either my eyesight is useless or the workshop manual assumes that the engineer knows where all this stuff is.

Thanks

Under the seat, just in front of the tool tray you wil see two relays fitted to the top of the mudguard.
The one on the right is the fuel injection relay, the one on the left the fan, that's taking left & right as if you were riding it........

Relays tested, fuses checked, fan checked, temp sensors tested, what next ?

I did think that I should be able to get continuity between the relay base and the fan connection but no, maybe thats the problem.

Im getting worried now, first date Snells had is 28th and MotoGP is 26th so any more help will be most appreciated.

Got some great help at Moto Rapido today and have changed the two relays and swapped the two temp sensors around.

Fan goes fast enough not to be able to see the blades but not fast enough to cool it down.

Have ordered two new sensors mention in Franks thread (I think)

Does anyone have any further suggestions ?
