Will a voltage regulator kill a battery?
Two things can happen. 1. the voltage regulator fails so that the alternator doesn't know the battery charge is dropping therefore the battery doesn't get charged. 2. The voltage regulator fails in such a way as to allow the alternator to overcharge the battery which causes the battery to overheat and fail, Sometimes an overcharged battery can explode.

What causes voltage on 1999 Saturn sl2 to go from 12.2V to 14V at random times?
The cause is the voltage regulator within the alternator (working normal). When the voltage higher it is charging the battery like after you start your car or have the headlights and wipers on. The voltage regulator keeps your battery charged up. In order to charge the battery, voltage must be higher than battery voltage.
