It was a nice week or so without any car problems but today when I drove over to wal mart with a buddy of mine I parked my car and turned it off. Realizing I could have easily parked 100 yards closer I went to turn the car back on and it just made a slow dyeing attempt to at starting. Now I get nothing. However, the battery is not dead, lights, radio, everything works fine, and even when I go to turn the key nothing dims to show a battery going out. So now i'm a little a confused, if the alternator was to die, then the car should continue to run until it depletes the battery, right? So what else could be behind all of this?
