Question by Electra-fried: Why does my low battery light on my car come on? I just replaced the alternator and the battery.?
Hi, so I start my car up every morning and the "low battery" light comes on.My dash lights are dim and my stereo makes a loud hissing sound that gets louder as I speed along in my car. After a few minutes the light turns off and my dash lights look normal again, but the hissing sound from the stereo is still there. I've checked all my connections to the batter and it all looks fine.

and what about belt if loose or old it slips and either alternator or battery wil work and if you have added a new stereo that could do it as well an dcant look at battery cables and tell if they dirty and best to have charging system check for drain or draw on power with radio on and off
