Battery has been ruled out. It's a Ford Motorcraft MAX unit that I put in not quite a year ago.

Sitting static tonight, before starting, battery was around 12.2 V. Once I started the car to test, it dropped down to 11.25 V. Alternator is done. Voltage regulator is integrated in the alternator, so no luck changing it on its own.

Prime Choice is damn cheap ($92!), but at only a 90 day warranty, it's not worth the savings when all the rest come with a minimum 1 year warranty. Maybe if I was flipping the car I'd go that route (or used), but since I plan on holding on to it for another 2 years, a reman with a long warranty is going in.
