Ford F-100 Battery Problem

I am having problems with the alternator light staying on. I have replaced the battery and alternator and it is still coming on. I have replaced battery cables and cleaned the ground. I have had it checked by the local parts store and not getting much help. Can you guide me in the right direction.
