I noticed my clock light (and nothing else) dimming in and out for about a month. Then my car wouldn't start without a jump. I took it to the nearest Autozone and had the battery tested and needless to say, it was dead and I replaced it. It has been a week and I noticed my clock light is dimming again. It will fade to almost black and then come back bright. Are these issues related---the battery and the clock? I am hoping it is not the altenator......
