  • Field Coil Grounding

    I have been chasing down the cause for a blown main fuse and it turns out that it is the field coil grounding all the way back to my main switch. I tested the continuity between the green and tan (disconnected from the RR) and that is 2.8 ohms but there is .6 ohms continuity between the green and ground and when I connect the wires to the RR it grounds out the main tan wire (.6 ohms continuity to ground). Do I have the two wires hooked up backwards? Is my RR bad? How can their be continuity to ground with the field coils disconnected from the RR? The bike runs, but I've already gone through two 30A fuses and I really need to have the bike able to make a 10 mile ride tomorrow.

    Any ideas?

    If either wire from the field coil reads to ground with it unplugged from the bike, either you have a bare spot on the wire or the coil is bad....

      Blown Fuse

      All of the XS11s lack a good ground from the factory and have much room for improvement. Poor grounds have caused everyone since the beginning of the discovery of electricity too many headaches. Improve your bike by improving the ground. Take the phrase "chassis ground " out of your vocabulary and replace it with "battery ground". You will suddenly be a happy electrical camper.

        Noted. I will definitely redo the grounds as I am sure that that will help things.
