when you remove the old regulator, check if the brushes are worn down unevenly, if so it might point to a worn commutator, in which case the alt needs to be seen to in any case as a bad comm. will eat through the new regulator brushes again.
your alt belt is not so loose that it is slipping, right?...one presumes you have removed and cleaned all connections on the alt (including the ground screw of the regulator, one of the 2 screws that holds it in)
