Last night, i was going to sportmart, as i pulled into a parking spot, just as i was about to stop, i rolled up my driver side window and then noticed the voltage go down, my head lights dimmed as well as my gauge lights, and then the car shut off. I didnt really think anything about it, but then when i came back out from the store, it would not start. I then decided to ask someone to help me jump it. It seemed to jump just fine, i then let it run for several minutes. Then i got in and began to drive, as i crossed the parking lot and turned on my lights(it was dark outside) the same thing happened, everything dimmed then the car decided to shut off. After that, i got out a battery tester i had with me, it read that the battery was low. I saw a pep boys across the way, so i went and bought a battery jumper. I did this and it started up again, as soon as i took the cables off, it ran for maybe a minute then died again, then i heard a clicking noise????, coming from the passenger side, sounded like from the alternator, maybe starter but sounded like it was coming from up top not down below? Can anyone tell me what that was? Any ideas? I also have a msd ignition hooked up, could this cause a problem? The msd box is next to the alternator, maybe this was clicking?? When i checked the battery again, it said flat. Finally, i decidied to just get a tow home, when the tow truck came, the guy tried jumping it as well, but again it couldnt hold the charge. This made him think it was a bad alternator. As soon as i get out of school im going to go home and figure this out. By the way i have a 130 amp powermaster alternater that is maybe a 1 1/2-2 years old? How can it go bad already. The battery now is a die hard gold,stupid sears..... between 2-3 years old. Also, if its just the battery, i was thinking about an optima? Should i get a yellow top or a red top? Whats the difference, better??? I need help!!!!!!!!!!!!
