Charging Woes

Last week my original alternator went, or so I thought. The battery gauge started reading 19+ and it eventually killed the battery.
So I replaced the alternator and battery. Still having charging issues.
When I left work, the battery gauge was dead. As I got closer to home, everything started to dim so I pulled over. The idle dipped very low as if it was about to stall then came back up to normal idle and the gauge read 14V and I confirmed this with a multimeter.
This morning I started it up and the alternator wasn't putting any voltage out, the multimeter only read 12.2V at the alternator post. I pulled the alternator and had it tested. Tested fine.

What to check next? 97 4.0L TJ

Check and see if the fusible link is corroded or loose?...

Edit: Or signs of it having been hot...

Do as Knucklehead suggests, but just a heads up for you, the voltage regulator is part of the PCM - Powertrain Control Module.
