Since you have two alternators, protocol dictates that you have the one that is out of your car bench tested at the local auto parts store. I know you're 99.9% sure that it's just fine, but a bench test there will confirm both the alternator and the internal regulator. You have to do it. Then when we swap that one back in, we'll search for the increased resistance in the main feed circuits by performing a voltage drop test while the system is under load. This is not magic. Houdini is not making electricity vanish before your eyes. Either the alternator/regulator is not putting it out, or something with resistance is eating it up (bad connection, "skinny" wire, partial short to ground, etc.).
