Ford Superduty battery and charging issue

My basic test was start the motor up, then disconnect the negative side of the battery. Does it still run? Alternator is good, could be the voltage regulator. Does the motor die? Alternator is probably bad, test for output voltage and amperage, as well as voltage regulator.

Niner, verified that there is no current between alternator and battery. Fusible links verified to have continuity (the two that I could find). AFAIK, voltage regulation is internal to the alternator. Don't know if there is a separate regulation module or not.
Right now, I'd wish to fire up the teleporter and land on Mex's doorstep with questionable alternator in hand. I bet the guy could rebuild it with his eyes closed.:B
