Re: 2001 4.0 alternator question

The original alternator could probably be made to work with an external regulator, but it would be a Science Fair project. It might even have the connections inside to mount an internal regulator. Open it up ahd have a look. Otherwise I'd use a junkyard alternator; they're not expensive.

I sure wouldn't try to get the ECU to regulate the alternator; that's just a bunch of stuff to cause trouble, and there's nothing to gain by it.
