I would definitely repolarize the generator as that is one of the first steps manuals say to do after changing the regulator or working in the charging circuit. Even if nothing was changed, doing it after a car sits a long time and then is brought back into service wouldn't hurt.

Once other question might be the regulator. I know there are regulators for pos and neg ground but not entirely sure what the difference in construction is. I believe it is mostly in the contacts but still there is a difference. That is something Jason might be able to shed a light on.

In your case, unless the replacement was exactly the same number, several on the forum have had issues with the wrong polarity regulator for the car or even some "universal" regulators causing problems.
