I need help guys. My daughter bought a 1991 tercel and sometimes when she is driving it the battery light comes on and the car dies and won't start again. The next morning you hop into it and it starts maybe a few times and the car dies again soon after the light comming on. Any ideas? I have replaced the battery last Friday and here we are Tuesday and problem is back. Just a note: I have replaced the radio to a pioneer cd player the week before everything started, but that could be just a fluke.Any ideas would be great.
