Charging system diagrams for 2002 dodge dakota
There is 4 gauge black/red wire going from te alternator to Fuse #2 in the PDC. The alternator and battery both connect (positive side) at this point. The alternator's path to charge the battery is from the alternator, to this tie point, then to the battery. In the wire, between the alternator and the PDC tie point, is a fusible link. This link may have broken or melted. That would keep the alternator from being able to charge the battery. I would check this wire for continuity and replace the link if necessary.
