[QUOTE="virtualmystic, post: 387710, member: 5576"] The standard automotive battery produces 12 volts on load (engine off and the lights on for example). The standard alternator produces 13.5 to 13.75 volts to effectively charge the battery (basically 0.25 volts per cell). if the voltage falls below these thresholds then it's time to have the battery changed or the alternator looked at. From your explantion it looks like you have a faulty alternator. [/QUOTE]
