Sounds like the alternator to me. Have you messed with any of the wiring lately? If so, check the grounds.
If you know somebody with a multimeter, test the battery to make sure that it's ~12v and jump-start the car to see if the alternator is charging.
If it is charging, the voltage at the battery should be ~14v with all your accessories off.
