What wire did you use to check voltage at the alternator the large one. The connections for the battery to engine ground should be cleaned should be .4 ohms or less. Does the battery light come on when you go to start the car. The one in the message center. On my 2000 Silverado this bulb excites the field for the alternator.
If your not getting voltage take it to an alternator shop and have it tested.
Please supply more information.
