Hi group.
I recently replaced my alternator with a certified rebuilt from Advanced Auto. Also bought new battery. Everything went smooth, car was driving and idling at 14.4 v after start-up. All good. Then 3 weeks later, my battery light comes on. Power won't pass 12.5v while idling or driving. Strangely enough, the power actually increases to 12.7 or even 13v when I turn the air on. The battery stays charged and starts up daily. If I increase the volume on.my stereo the voltage dips a few points to 12.1-2. wierd.

Could it be a the tensioner pulley not turning the belt tight enough on the alternator? Is there an inline fuse that could be causing this drain? Any help would be greatly appreciated. I do not want to have to replace the alternator again.

You might need to...there are several reports here of aftermarket alternators and starters failing soon after installation.

Get the new alternator LOAD tested.

Also, you may want to search topics about the ELD (electronic load distributor).
