Have you checked the fuse on the charge line? It should be in the fuse box under the hood.

Something else to check is the overrunning alternator decoupler.



Does the alternator have one of these? My first experience with one was on my 2007 Caliber. It let lose and the alternator stopped charging. After I got the alternator pulled out I spun it and watched the pulley spin freely and the brushes never moved. Wouldn't put it past parts store quality for one to be bad on a rebuild.
