So I wanted to close the loop on this thread for anyone who looks it up in the future. If you're reading this - REPLACE THE DAMNED SWITCH
As
@slantsixdan stated, I don't have the wire that you guys keep talking about from post #4 -- I have the "shuttles" shown in the picture in #12 with red arrows that are small rectangular plastic pieces with a copper contact on each side that correspond to the wire contacts and slide left-right with the signal switch.
After trying every combination of replacing them in the switch, understanding the schematics of the wires, removing the ash tray and testing the flasher, and after cleaning/adjusting the contacts, etc....let's just say they are still highly suspect and certainly not reliable for safety. My lesson is learned....contact
@slantsixdan and get a new-new-stock replacement and call it a day.
I did. (thanks again to Dan - order placed). I'm sure I'll be better off in the end.
