When I start my car my radio clock resets its self to twelve o'clock also when I m driving all of a sudden my dials, radio, message board on dash and all lights start flickering. Then the car totally dies. I pop the hood and mess with the battery cables then try to start it and it does. My battery dial shows at half and starts to move back and forth. I had some corrosion on the positive cable but I cleaned it. Does any one know what is going on? Is it my alternator or my computer? I don't know? HELP!!!
