If you are sure the alternator and charging system is working properly, It may be that you need a new serpentine belt and belt tensioner. Check all the idler pulleys also when you have the belt off.
Also if you have any accessories drawing a lot of juice, such as a big stereo or a lot of add lights, your alternator has to have the proper amperage output rating to keep up.
