Cranks but won't start. Unplug ground at field spade on Alternator and it starts?
Try unhooking that field circuit, then insert your meter and see what that circuit is drawing, both, with key in "run" and with key in "crank"
While I went into house cause its 100 degrees in garage I left battery on 2 amp charge for 4 or 5 hours.
Field current readings:
Key in run: 1.4 amps
Cranking: 1.12 amps
All the sudden car now starts? And starts every time?
Unhooked amp and hooked field wire in engine harness back up. Starts every time and sounds like strong healthy start.
Some more voltage tests:
Volt drop at Ign 1 at VR, disconnected at ballast and VR, engine off .2 volts and spec is .55 volts or less.
Carb stud to neg battery terminal, engine running: .05 volts
VR body to neg bat terminal, engine running: .05 volts
Alternator to positive battery volt drop, engine running: 1.5 volts
Alternator battery stud, engine running: 15.6 volts
Battery engine running: 14.2 volts
Battery after taking for short drive, engine off: 13 volts. Banged some gears light throttle car seems to run really good. Amp meter shows it was charging, meter steady while driving, and was reducing amount of charge as I drove
