OK. I got it working, finally. I tore the switch apart on the confidence that the wiring was fine because the calibration flash worked every time I turned on the ignition. But, while the switch was in pieces something dawned on me, Wait, the calibration flash works when the wires are connected to the bike but not yet connected to the switch!
So I expected the problem wire to be the left signal between the STS and the handlebar switch. Sure enough, when I removed the plastic and unraveled the electrical tape, the offending wire came loose from the bullet connector. I made one last stupid mistake by solidly crimping on a female end and went to connect it to the....female end. Oh brother, tore the female end off and crimped on a male. Good grief, the old adage about knowing enough to get yourself into trouble definitely applies to me and electrical stuff (plumbing too btw).
I have the brake module to install, but not this week, not after this hassle. I will be on America's 911 Ride by the end of next week and I am not risking anything else going wrong. We ride from the Flight 93 crash site on Friday to the Pentagon. Saturday we ride from the Pentagon to NYC and Sunday we ride across town to Ground Zero. It is a fanstastic ride organized and led my MC cops.
Thanks again for all who helped me through this mini nightmare. But I love those self cancelling signals. And my switch does work a little better after I disassembled and cleaned it out.
