I dusted off my schematic. 4 wires to tach. Ground. Fused power off Fuse #1. Hot in from Ignition Switch. And finally hot out to the Coil. It looks like if the car is running ok, then the last 2 are working, signal into and out of the coil. So I'm thinking either hot from Fuse #1 or Ground is my culprit.

And of course to check these, I'll have to find someone lithe.
