Ugh Theft Error and Comm Error

[pdksh]

Got burned AGAIN. When I rotated the motor a year ago to replace the front cylinder top end, I must have been excited to see the girl run again. I forgot to install the star lock washer for the ECM ground screw that’s on the front cylinder!!! I was plagued all last season with COMM and THEFT errors. I assumed I had a break in the wire harness and knew I would have to rotate the engine to check it out. When you pressed on the wire harness under the left pod, she would fire up and run for a day or two.

I rotated the motor and pulled the tape off the wire harness to the ECM. Intermittent COMM errors. I even metered the wires from the ECM to the dash. Just about to give up a noticed the ground wire on the front cylinder was loose. DOH!

If it’s a BUELL and you have a gremlin, it’s a ground!!!

I agree. People like to push back when we say to check and clean your grounds, but there is a reason why. A little effort can go a long way.

I’m glad to hear you found your gremlin!
