I just read about your latest struggles, so you'll find updates with a lot of info about your ignition system, including diagrams, specs, the complete wiring diagram for the car and even a troubleshooting guide. As you said, this is in many respects a service manual. Back then the owner was expected to do all "routine" maintenance, which was pretty extensive. My truck stalled out on me last night so I had to push it the last block home. Fortunately it is very light. I'll need to do some troubleshooting of my own soon. Good luck getting yours running!
