I found the above photo here, in a great collection of vintage motorcycle photographs, and it completely summed up the frustration of what happens when vintage motorcycle parts stop working for some unknown reason. Lights flicker out and forward motion ceases and you are left all alone with the gods of physics. Sometimes all you can do is stare and hope for a sign from the heavens to bonk you on your thick skull and tell you what connector to wiggle to continue on.
Why yes, I was rebuilding my electrical system on the bike again, why do you ask?
