Make sure that you have good , clean grounds everywhere. Run some more grounds if you have too to be sure that you have a good ground from: Batt to engine, frame, and body. Run seperate grounds to the alt and reg to be sure thay are well grounded. Sometimes paint, grease, and rust can keep them from getting a good ground. You cant rely on just the fact that the alt is mounted to the block which is grounded, and the case of most external regulators needs to be grounded too. Also check to be sure that you have 12v at the batt term on the rear of the alt. That wire , i believe has a fusible link in it. Make sure your belt is good and tight. From your description, id bet on a bad ground, assuming all these new components test good.
