URGENT! Bike is overheating, fan won't turn on

My bike is just barely a year old and has only 7000 miles on it and it overheats. The fan will not kick on and the temp gauge maxes out and the red light will come on forcing me to pull out of traffic and wait. I pulled the fan fuse and it WAS blown, but I replaced it with a new one and it still will not kick on. Where is the Fan relay located? My manual has no information on it so I am at a loss. I am on vacation with the bike and I really wish I could fix the problem without blowing my vacation money taking it to a repair shop.

The relay is under the seat between the battery and the regulator/rectifier. The fan is the only thing on that circuit - it should be a 15 amp fuse and the fan should draw around 5 amps, so plenty of cushion there. Either the fan itself is shorting or the wiring insulation has rubbed and caused a short to the frame. It would be helpful to know if the fuse blows as soon as the bike is turned on or if it is when the fan tries to turn on. That would tell you if the short was before or after the relay. Also, does the fan spin freely or is it binding? If binding is it bearings or are the blades caught on something?

If the fuse blows right away it isn't a problem with the fan but probably in the wiring between the fuse and the relay.

I think those relays just unplug...you could try unplugging it to further narrow down the short. While I've never seen it happen, I guess the relay itself could short.

As far as I can see no, the fan looks completely fine but will not budge unless I put excessive force on it. Shouldn't of let that warranty run out . I'm going to limp it home as best as I can and work on it from there with all my tools. I'll post in this again just in case anyone else has the problem.

Yes, can you tell if it is internal or external? Could be the difference between an expensive repair and a quick fix.

Edit: posted at the same time.

If you have to stop for more than several seconds, you could turn the bike off. Slow traffic would be a problem, though.

Just out of curiosity, do you ride a lot in rain or dust? You (meaning I) just don't hear much about these fans seizing up, even on bikes ridden in harsh conditions.
