shercoman2k8 Posted September 27, 2008 Report Share Posted September 27, 2008 Any of you know what voltage and resistance there is on a fan on the 06 sherco's 125cc? Need to test cos its packed in! Quote Link to comment Share on other sites More sharing options...
copemech Posted September 28, 2008 Report Share Posted September 28, 2008 You should be able to test the fan motor using a 12V battery. If the fan runs via the battery, yet not on the bike, likely your rectifier is bad as it is required to convert the AC to DC power to run the motor. I suppose you have already by-passed the thermo switch by connecting the wires together directly? Hope that helps. Quote Link to comment Share on other sites More sharing options...

shercoman2k8 Posted September 29, 2008 Author Report Share Posted September 29, 2008 Ultra confused now!!!! Tested it off a 12 v battery worked, bypassed the thermo switch and then tested off the battery and it doesn't. Could it be a loose connection anywhere?

Could it be a loose connection anywhere? I am not sure exactly how you have done this, yet basically, using a test light or voltmeter, you should have voltage at one side of the fan connector and none on the other as your tester is connected to earth(frame or motor). If you have a bad earth connection to the fan, you will have voltage on both sides of the two wires. If you have no voltage to either, you will need to backtrack on the yellow wire to see if you have a bad connection somewhere or a shorted wire. The yellow wire should be the input to the thermo switch, when connects to the red and sends power to the fan. Hope that helps. Quote Link to comment Share on other sites More sharing options...

Copey, you've solved my problems again, your a big help Cheers, the red wire was loose where it connects to the fan! Quote Link to comment Share on other sites More sharing options...
