Help! Had my CBR600F4 since just before October, and been riding during the winter (cold in the UK) with no problems. Now the weather is hotting up, I seem to have a problem with the engine temp going sky high. Cheched all the normal stuff, and found the fuse for the radiator fan had blown. Replaced it and thought that was it. Wrong. If the engin stays cool enough not to need the fan, all is well, but as soon as the temp goes up (like sat in traffic) and the fan tries to kick in, the fuse blows. I find myself at the side of the road waiting for things to cool down before I can set off.

Before I take the thing to bits, then get mad and take it to a garage, does anyone know of any problems with the fan fuse, or is it just a simple short somewhere?

Cheers.

 

you have a short somewhere. you'll need to follow the lines. they may be crossed somewhere.

 

What Tahoe said. Check the wiring. If your wiring is solid, get a new fan motor/fan.

 

double check you have the right size fuse also make sure the fan spins freely

 

Sorted! After spending ages following the wires from the fuse box, finally got to the fan.......and found a small twig lodged between the blades. Pulled out the twig and hey presto, the fan nearly took the end of my finger off. With the fan not able to turn, it must have been overloading the circuit and blowing the fuse. All's well now. Thanks for all your help guys!

 

LOL...glad you sorted it out!
