I would bet that if everything else is fine, it's the regulator. Not sure on 92 but I know 93-95 the regulator was built into the ecm. I had the opposite issue with mine. Overcharging at 18.2v, not pleasant. Replacing the ecm took care of that, but now mine won't start on the first roll over like she used to... Give a little to get a little I guess.

91-95 the regulator is in the ecm. Pull the alternator and take it to be tested at any good parts store. Chances are the alternator is bad or the cables are bad. Check your fuses in the fuse block under the hood. The big fuses are the alternator output and there is a smaller fuse for control.

Que hit the nail on the head. I just had a few similar problems (charging at 19v and not charging). For me, the first fix was a wiring short.

Obviously, to start, check your fuses at the PDC. If all the fuses are good, check grounds. The ground i am specifically thinking of is the ground molded into the black box connector that attaches to the alt.

After testing the alt, if it comes back good, check continuity between alternator and ecm using a volt meter.

Also, the charging gauge is notoriously inaccurate on these jeeps. I would use a volt meter to check exactly what the charging voltage is when the car is on. There is a possibility that your gauge is no longer working.
