Hello Gents,
I have a 2004 Buell XB12s. I was on a ride sunday hittin up the canyons. Stopped at a gas station on the way back and when I started it up the engine light came on. The code says open or shorted fan wire. I started my trouble shooting at the ecm. Where the manual says its wire G6. I put my testing lead on there and triggered the fan manually through ecmspy. I didn't get any voltage from that wire. That should be the voltage line going to the fan correct? Theres two wires that go to the fan. Orange/Black and Yellow/Brown. My understanding is I shouldn't have contunity through the fan and I should be getting a voltage through one of those wires to the fan correct? Is there anything else I can check to diagnose my problem.
 
disconnect the fan at the fan, see if it will run with 12 volts jumped to it, does your rear jug leak at the rocker boxes? That is what usually will make the fan go out, did you check the fuses, don't remember if the fan has a dedicated fuse, really doubt it is the ECM tho, iether temp sensor or fan is about all that can go wrong
