2002 F-250 alternator problems!!!

Two new batteries and new alternator a month ago... Now the battery light in the dash flashes on and off....sometimes it stays on for 2 or 3 mins.
Does anyone know what could be the problem. Are where I can get the wiring diagram for the charging system?

thanks for your help!

What are your batteries reading while the truck is running? Down around 12V or closer to 14V?

If lower, your wire between the alternator and batts could be bad. Just a suggestion.

AutoZone Alt? The only one I would buy is the DB Electric Alternator, far better than anything you will find at any auto parts store. Also check all cables going to and from the Alt.
