HELP! Charging/Wiring Problem

nothingbutdarts said
Ohm meter check from the alternator case to the voltage regulator. It should be very close to zero!

Pull the plug on the regulator and check the terminal on the plug, the blush should have battery voltage with key on. Ohms check the green one from the connector to the push on field connector, it should be at or very close to zero.

If these check OK and you know the alternator is good, I would then think the regulator is bad. You did say you had battery voltage at the charge lug on the alternator, (the factory 12 gauge as you said) correct?

Thanks for helping, Nothingbutdarts. Here's what I came up with:
Ohm meter check from the alternator case to the voltage regulator case was infinite.
With key on, blue wire on the regulator connector has 11.2 volts.
Ohms test of the green wire from the regulator connector to the push on field connector is 0.
Voltage at the charge lug on the alternator (through the stock 12 guage harness wire) is 12.75 volts.
