What do you have for voltages on the two small plug-in wires on the back of the alternator? The blue one must have 12 volts with the ignition switch turned on, and the green one must have less but not 0 volts. If you find the exact same voltage on both wires, be sure the voltage regulator is bolted solidly to the firewall.
