Well, today I was driving along with the usual battery light on when I noticed the clock was getting dim so I shut off my headlights and by the time I got to AutoZone, the car was running, but the batt was so low that I couldn't use the turn signals. I got the battery checked and checked my terminals. Both were good. I had to jump the car to leave AutoZone and then the battery light went off. I think my alternator is siezing up or is just tempermental, because driving home it was fine the whole way. I still drove with my headlights off.
