check all your connections and make sure your grounds are clean and tight


have you checked if its actually charging?


Have you checked all your grounds? Corrosion or shorts on any wires? Voltage drop on all cables going from battery, alternator and starter? Did you get your alternator from Autozone? I replaced 5 starters one time before getting a good one from Autozone. I would get an OEM alternator or Denso. Not sure what they use. See if computer controls your voltage on your model. You could have a bad PCM if this is the case. What is a voltmeter reading when car is on and you are touching battery? Low or high?
