Black 2008 Saturn Sky Redline (manual)
If you don't have 14 volts in the system while running, it is definitely an issue with the charging system. I had an issue where mine died while on the interstate. Charging the battery would limp it along for a while. Changed out the alternator and still no charge. Turned out it was the fusible link between the alternator and starter that had broken. Lesson I learned is to test the alternator before assuming it's the problem. Most parts stores have the ability to run a diagnostic on them.
