Put everything back to original. Start the car, momentarily ground the field terminal on the generator. You should see 15-16v at the battery. Post back the results. This isolates the gen output potential.

I DID AS YOU SUGGESTED GROUNDED FIELD TERMINAL, NO INCREASE IN VOLTAGE AT BATTERY POSTIVE POST.
ANYOTHER SUGGESTIONS?

Check for continuity from the main terminal on the generator to the A terminal on the regulator. You should have a wiring diagram to track down the circuits.

Forgot, when you momentarily ground the field on the generator, see if you have 15v at the main large terminal on the generator.
