Best Answer

A fully charged battery will read 12.6 volts with the engine not running. It will read 12.4 at 75% charge, 12.2 at 50% charge, and 12 volts at 25% charge. With the engine running at idle you should read 13.5 to 15.5 volts. Any lower or higher and the alternator may be defective.

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.

What is a short to voltage in an automobile?

A short to voltage is when a wire that should not have battery voltage has battery voltage. This would happen if a wire had rubbed through another wire. The other cause would be an electrical component failing and sending voltage down a wire that it shouldn't. NOTE: Shorts to voltage are very uncommon. I specialize in electrical automotive repair, and I can not even recall one time I have seen a short to voltage.
