Switch or motor?

(1/2) > >>

ghostbiker:
I noticed shortly affter the winter if i was in realy heavy traffic and couldnt be arsed to filter (happens now and then :P ) i got the red temp light pop on, went off again as soon as i got moving or turned engine off.
Also noticed it 3 or 4 times now when on charity runs (only this year, was fine last year) that again in slow or staionary traffic the red warning lamp comes on.
So today i went out a rode slowly round town for 15 mins or so to try to make it happen, sure enough affter a while the red light came on, and cleared as soon as i crept the speed back up.
so tried again and got the red light on, this time i got off the bike and checked the fan.... No fan on !!!
now im 90% sure the fan should be on long before it gets hot enough for the warning light. so i must have a problem.


In my VERY limited electrical knowlage it would seem to me there would be a switch to turn the fan on once it gets to temp "A" and a 2nd or maybe the first is variable to set the light on when the temp hits "B"

so either the switch is faulty or the fan motor itself had died.
but how can i find out what one it is?


PS sadly i doubt i will get many replys as most ppl dont even know this board is running yet lol. DAMN YOU YUKU!!! :P

The fans should come on automatically when the temp reaches 100 degrees and go off again when it drops below 94 or 95.  There is a relay located under the seat which controls this.  Don't know where the temp sensor is though, sorry.  I have actually fitted a flick switch to turn the fans on manually as I feel that 100 degrees is too late to be bringing the fans on.  As i live in a hot country, I turn the fans on when I am in town by wiring direct from a switch to the relay an in effect making the contact.  You could test the relay by simply bridging between the terminals to see if the fans come on.  If they work then the problem may be with the sensor if not then the relay will be at fault.

The relay is small and black with a white/clear connector coming out of the main loom. It is located behind the battery and directly under the front seat release mechanism (not key on the side but where the seat clips into).  The white/clear connector has four wires - Red, Brown with Green stripe, Red with White stripe and Grey.  The Grey wire is much smaller and this is the one you want.  If you touch a wire between where the small grey wire is connected and the battery NEGATIVE terminal (ie earthing the connection) with the ignition on the fans should come on.  This is a volt-free contact so no chance of shock!  As I said above, if the fans run then the problem may well be with the temp sensor.
Also setting at what temp the fan comes on is not adjustable without adding more complicated electronics.

The link I have included below is what I used to install my manual running switch which has some pictures and may be of use to you.  It is for an older model FZ1 but the principle is the same.

Hope this is of use and good luck. ;)

ghostbiker:
Spot on, i will take a look tomorrow
I did think about fitting a switch, but to be honest its rare i sit in traffic and even rarer that we get warm weather in the UK lol

ghostbiker:
Hmm well just taken a quick look (wish my damn haynes manual would arrive :( )
i think i found the 4 wire relay you refered to but its not exactly where you said and its not the same wire colours lol.


i think this is the relay


the 4 wires

2 wires seem slightly thinner (but not by much)

Why not just change the fuse.....?
 
It's in the FUSE BOX by the way.  :rolleyes
