Brian... thanks. Have added ignition switch to T77's roster. If you have any advice on how to test it... that would be appreciated---I have no idea what wires do what there. Appreciate resistance and voltage input.

We test the ignition switch with a new unit by pulling the switch out of the dash, replacing the existing mechanism with a new one, then use a screw driver as the key. Look for changes in voltage between old and new and also crispness in the starting action when the tumbler is turned to each notched position. If your ignition switch is original I would replace it as it is a wearable maintenance item.

Back to dying issue... have decided to troubleshoot in layers---simple layer first, more complicated stuff later. Everything that can be disconnected, junctions cleaned and prongs expanded slightly, CDI-to-distrib at both ends inspected... that layer's done. Car's been driven almost 50 miles since... NO dying over those miles. Appreciate the input on this
