Hi Terry:

Good. We're making progress. Your results are consistent with the headlight switch diagram.

The only purpose the third wire in the left side light socket serves is to secure the bus bar. It gets plugged into a dead end in the five hole bakelite headlight connector.

As for the ground through the green wire when on "tilt" and "pass" as long as the bus bar is connecting pins 1 and 2 in the headlight socket that shouldn't matter because there is already a shorter path to ground in the headlight bulb. It may be that the column switch bridges the unused filaments in the 1 and 2 positions (that switch is like a clever question on an IQ test). Anyway, just take both headlight bulbs out and verify that the circuit becomes open. If you had a short circuit you would be burning out fuses like crazy (or the burned out left bulb is the only reason you weren't blowing fuses). If you want to be sure substitute a test light for the fuse and move the switch through the positions. It should glow or be dead, but if it suddenly burns brighter then you have a short in the harness or a wire hooked up wrong. To be sure, remove all bulbs and retest if you find a problem.

Those special big fuses are available through MSC Industrial Supply and should be replaced anyway.

Glad to hear that your three filament system is intact.
