If the charge light comes on then you do have an alternator problem, possibly worn brushes and armature, however this is a computer controlled system so you may also have something going bad inside the computer. Did they mean that the battery had been overcharged? Did the battery short out any cells? From what you have stated it really sounds like your going to have to replace the computer, alternator and battery before you get this fixed . You might want to have a shop check the system out before you start throwing parts at it. You might have a wiring issue along with a bad alternator.
