Brand New Battery, and New Alternator. 1 Day Old.

The Alternator is not charging the battery. What is going on and how should I fix it?

Please Help. Desperate at this point.

I have the same issue. O Reilly's said their tester said my new alternator had a bad voltage regulator. Fat chance. Did you ever get yours figured out? They said the dealer might have to "re-learn" the alternator by computer.
