Welcome back. If the alternator is good and not producing current, then it either is not getting power supplied to it or the is an open between it and the battery. Since the light is not turning on inside, I suspect the open may be between the alternator and battery. Have you checked for a faulty fusible link?
Take a look at the schematic listed below. It shows all of the for the starting and charging system. The first one I would check is the 12ga-blue one between the alternator and battery. Check it for continuity. If it is good, confirm that the power from the starter (also a fusible link) is good. I had to break the schematic into two pictures.
Let me know if this helps.
