if you've got 14 volts at the battery terminals then the alt is putting out. the battery alone will only give you about 12. throw all your accessories on when the jeep is running and test again to do a load test on the alt. if you still have 14v (you may need to rev the engine a bit) then the alt should be good. make sure you test against the terminals themselves and not at the cable clamps as a bad connection between the two could give you a false reading.
