I do have a question for you. About 6 months before I was driving and my car died. I tried to jump start and all the lights on the dashboard came on and it died again. I had it towed to a shop and they said I have to get my alternator and the battery changed. Then in September car died again and had to be jumped. I took it back to the shop and they said my battery was bad and replaced it under warranty. Now yesterday I was driving and the battery and brake light came back on. I got home checked the brake fluid and the connections on the battery and everything is good. Now everything I read online points to a bad alternator. Do you think that it could be the alternator (only 6 months old) or did the battery die again. I would greatly apperciate your opinion before I listen to the mechanic and spend another $350 on the alternator.
