Yes!!!! I finally got the bike to turn over! Turns out my problem was the "side stand relay" which is on the left side of the bike, near the horn and ignition coil. I had originally disregarded it because I'd assumed it was a turn signal relay. But thanks to people's advice, and Bobberts thorough run down of the electrical system, I realized it was actually a safety relay that supplies power directly to the kill switch. AND I fixed it by accident... I took it off to check for continuity, and at first I had a bad reading. THEN i dropped it. Checked it again, and the reading was good! I guess that drop knocked some things into place.
Lessons learned:
1) Don't assume you know what a component is. ALWAYS refer to a good wiring diagram.
2) Give your relays a tap or two before tearing into the harness and pulling your hair out.
Next steps:
Put the ignition cap back on and test for a spark. If I get a good spark, I will take out my jumper wires used to bypass the safety switches, one by one, and keep checking to make sure it all works. Then start her up, tune her up, and hand her back over to what will be a very happy girl.
