Never ever pull off a battery cable on anything after 1978,the power spike that happens can fry every electrical componet the vehicle has, luck for you the alternator was not energized, this Jeep's charging system is computer controlled, so if your alt light turns on when you first turn on the key and it doesn't charge then the computer system will have to be scanned to see if the computer is actually sending the signal or not, if not the computer will have to be replaced, if it is then there is a broken circuit somewhere in the wiring. I could tell you a tale about a person that did what you did, but let's just say it cost him a lot of money to get his car running again.

Also check for a blown alternator fuse.
