Thanks, but there's a lot to figure out for the future. Ain't divorce wonderful?

Problem solved.
Once I saw that alternator connector I highly suspected it was the problem. Installed a new Napa 35 amp alternator this morning with the new shinny clean connector. Tach sits steady at idle and best of all, I now have 14v at idle, with all 4 headlamps, flashers and brake lights on. Confidence level is high once again and I'm a happy camper. Survivors are nice, but they come with hidden gremlins and need TLC.

P.S.
The ground wire is on the RR manifold bolt and is bolted to the firewall. It shares that spot with nothing else.

Apparently I spoke too soon............as usual. Left for a cruise night and I noticed the tach jump. looked at the voltage gauge and it was at 16v and erratically jumping back to 12 or so. Even noticed a misfire or two. Having lost confidence, I turned and went back home. The volt meter has never been erratic like this before so I am suspecting that something took out the voltage regulator. Going to replace it............again. Will update once replaced. Confidence level low, frustration level high.

Oh those gremlins

Well, it was NOT the voltage regulator. The cliff's notes version is that it was loose studs on the factory ammeter. I've heard the horror stories about them so I figure as long as I had to pull the wires, I may as well just bypass the damned thing and kill two birds with one stone and be on the safe side. Tach is now dead steady as well as the volt meter, which holds a steady 14.5-14.7 ish. One gremlin caught and executed. Confidence level back up.
