So about 6 months ago I replaced my alternator and my car battery at the same time. I had feedback coming from the stock stereo when accelerating. It seemed to fix the problem for about 3 days then the sound came back. I tested all my wires from the battery to the alternator, starter, aux fuse box etc.. and they all seem fine. Now when I start my car in the morning the low battery light stays on for a couple minutes and all the electrical is dim. then it goes away and everything is fine. If i let the car sit for 2 or 3 days, i have some trouble turning over. You're prolly thinking its some kind of battery drain when the car isn't running... its not. the voltmeter doesn't show any current being drawn when the car isn't running. I had the battery tested Saturday and was told it was faulty so I replaced it. No changes. had the alternator tested, it tests fine. What have I missed? Still have amp noise and low battery light. Its a 2002 GTP 3.8l S\C
