Ignition experts needed

Spent all day in the garage. New voltage regulator today, along with fixing a couple really bad connections at the alternator. Checked my tach wiring and all the new ignition wiring...again. All looked good.

New plugs, nice new wires and billet looms. And checked battery voltage. 12.8 volts. Now fire it up and noticed immediately it ain't cold blooded anymore. Idled on it's own, no choke in 2 minutes or so. 50 degrees in the garage today.

Batt. voltage at idle 13.4 and at 2000 RPM, 14.7. No more crazy alt gauge.
And the big thing is....it didn't die on me. Ran for 45 minutes and never burped.
I can't believe a starter relay, a voltage regulator or a couple bad wires at the alt could have been the problem from day 1. Hope I'm not jinxing myself, but I think it might be ok.
Gonna drive it tomorrow. Not too far from home, either. I might just go around the block 100 times or so.
My fingers are crossed :-)
