So, saw my red battery light on the dash today (my son says it has been lit on and off for the past week and never told me).

Anyway, took it to Autozone to have them put the tester on it and battery was charged, starter was good, and alternator was good. The drive there the light was off. On the way home, light went on and off again twice.

I am thinking my alternator is on the way out and was going to replace it. since battery checked out fine. Thoughts?

You can simply replace the regulator/brushes unit on the alternator if you want. There are apparently two types, so you need to know which one to order.

Sounds like more than I would want to do unless you save a bundle by doing so. When you say two types, is it like there is a separate alternator for my 3.9 D1 vs a 4.0 D1 or two types for my 3.9. Any idea on how to know the difference?

It is the habit of buying whole alternators instead of replacing the regulators/brushes that led me to a collection of 4 broken ones.
But I am on the path of cleaning up the pile. Two down.
If only I learned how to rebuild the starters...
