hi, can anyone advise,,

i have txt 270 1999,, until yesterday it had a horn/indicator unit on the handle bars ( probably for road use at some point),, as this was interfering with my riding i took it off,, and cut all the wires attached to it,,,

my first ride after doing this lasted five mins before steam was blowing out of the overflow pipe on the radiator,, fan now not working,, is the wire cutting related to radiator/fan problem?

cheers
Paul

Chances are yes you cut toomuch out. try ,http://www.gasgas.com/Pages/Technical/Electrics/wiring-kokusan-96-2000.html . I can`t quite remember but it seems there was a spot in the harness that three yellow wires had to stay attached, maybe someone else will help?

I agree, the wiring diagram is a good place to start.

You'll notice that there are actually two seperate power generating systems, one dedicated to the CDI ignition and the other to power the lights, horn and fan (there are different generating coils in the stator for ignition and accessories and they are not interconnected, although most riders often think there is only one power source). Depending on where you cut the wires, you may have cut the power to the fan (the red wire in the 99/2000 diagram, but often it is yellow to the fan). I'd trace down the harness and you may want to take off the "extra" stuff you do not need while you are at it. You WILL want to install a killswitch in the process, as you have probably also cut the killswitch wire housed in the handlebar switch assembly.
