sounds like you got a bad alternator from AM. i would call there tech line and see what they say

Here's the charging system overview:



You should check the fusible links, and the 20A fuse in the battery junction box--the generator¹ will not charge the battery if the fusible links (both) or the fuse are blown.

-----------------------------------------
¹ - Yes it is a generator, most of what we call alternators in modern cars are actually generators. Alternators produce AC voltage, generators DC.

Back when the rectifying diodes were external to the rotating unit they were alternators, but now that they are internal the unit is a generator--Ford started using the proper terminology in the late '90s.

Yea, AM is really good with their customer service. So give them a call and see what they say.
