Did you clean/check the commutator inside the alternator when you replaced the Voltage Regulator? I normally send it down with 600+ grit sand paper and blow it with compress air. It is normally the VR problem when the battery light is dimly lit. Your old VR shows the brushes are not of equal length and badly worn.
I would at least try cleaning the commutator, replace the alternator before checking ground, in that order. I believe grounding is a red-herring all the time.
