Re: 1991 jeep wrangler: alternator overcharging
It sounds as the voltage regulator which is built into the back of the alternator has stuck. Occaisionally this even happens on new ones. Would suggest taking the alternator back as it shoud be under warranty.

Have you checked to see whether the battery lamp illuminates with the key on only. If not then the fuse to is blown or that wiring to the field circuit is faulty.
Did you replace the parts with new ones?? You did not state.
No battery warning lamp no charge simple.
Have you had fuel pressure tested, and/or filter changed. Have you checked for plugged exhaust, such as catalytic converter? Quite often engine will also run a little hotter than normal when exhaust is plugged.
Most likely it is the voltage regulator that's going bad which allows overcharging. this is inside the alternator, so it most likely needs replacement. you could pull it out and take it in to most auto parts stores and they would check it to make sure.
