Voltage gauge pinned ??

Driving home yesterday i heard a beep...I look and see the dash light says check gauges, ok...so I notice the voltage needled was pinned all the way. Jeep seems to be driving fine so I keep going. A minute later it went back to normal..then suddenly a minute later went back to pinned. Then stayed like that for the rest of the way home.
Any ideas???

Have you checked with a multimeter to see if the voltage is actually changing? Could be the voltage regulator in the alt... If your voltage is good ~13.8-14.4v then I have no clue where to start.

this afternoon the jeep decide to not start. There was just NO response at all. Tried 2 more times and it started. The voltage gauge was normal, but the rpms stayed around 1800-2000 all the way home, and the now the airbag light was on.

I came home disconnected the battery and reset the computer. Waited 10 minutes. Put it back together and it seemed to idle fine in the driveway...no warning lights either.
