Did you have the battery load tested to make they put a good one in, use the second number on it forgot the name the one to the right of the first one ( it is a sticker), and divide that in half. Then load it with that much, if the battery drops below 9.6amps during the load it is junk already. With the alternator Autozone does that to, it is helpful if your car has a tach, as you need to idle at 2000 rpm.

Is your engine ground cable connected? Maybe the alternator has no chassis ground?
