BEFORE condemning the internal regulator, check with a test light to see if there's battery voltage to the #2 terminal with the engine "OFF", then "ON". If there's battery voltage at the connector, be SURE the terminal is clean so it makes good contact. The regulator terminal is STEEL, and typically rusts, making for a poor contact.
