Did you have the battery tested too? If you got the Alternator checked out and it is pumping out 14V when the car is on, and the battery won't hold a charge, the battery is weak. If the battery checkout out fine, then I would suspect you have a parasitic draw. Meaning a circuit on the car is drawing amps and draining the battery. You can test what circuit that is as well. Look online on how to perform the tedious tests
