Unhappy Fans not working

Took the SPR out for a lovely blast yesterday but my pleasure was rudely halted by a rising temperature gauge. The bike normally strays up to 92 but (was hot granted went above 100). I noticed the fans were not working before It spat coolant out of the overflow pipe (about a half a cup full). luckily I was close to home and took off the very hot fairings......my questions are "what is normal temp for the F4's" and to save me tracing back every wire...is there an easy check or fix....i was thinking of putting a power feed direct to fans to check working (naturally) but after that where should i look. Appreciate there are loads of forums on this subject and have read most of them.....really appreciate anyones thoughts as keen to get back out there...cheers

if I remember right its around 102/104 degrees that the fan kicks in,

if your fans are not working check the diode as this was the fault with my EV03, which was discovered after many hours/days back at the dealer


check back the threads on this, there are a few

use the search tool above.

Check the relay on the right side of the frame behind fairing, near the top of the rad. Mine melted when too close to headers.

This happened to me, it was the little black relay behind the fairing just in front of where your right knee might be.
Not expensive, unplug it and take it to any electrical component place, should be able to sort you out.

Mine is a four-spade connection, the only marking I can see is '13/03/03V'. I've no idea what this means.
