Re: Electrical cut-out R1100RS tipped to left

[John Merlinw Williams <jmerlinw@xxxxxxx>]

Timo, Bob:

Thanks for the suggestion. I had checked the side-stand switch, which  
I had replaced the previous season. That wasn't the problem, but I  
began poking around in the wiring a bit more and discovered that a  
very slight displacement of the wiring bundle that begins at the left  
handlebar grip appears to be the problem. If I move that bundle just  
about 1/4 inch at the point where it curves under the tank - all the  
electrics go off.  That bundle appears to begin at the handlebar with  
the low/high beam+horn+left turn signal, it gathers the separate  
clutch switch cable and also joins with the the ignition switch  
bundle. Must be a broken wire in one of those. I played most with the  
clutch switch wire and it doesn't appear to be the problem - must be  
one of the larger bundles.

Gulp.
