I am not suggesting to throw money at it, I am suggesting to troubleshoot and verify what the problem is before proceeding. I am sorry if I gave anyone a different impression. A lot of the rebuilt alternators that are out there now are crap, and generally most mopar guys have a stash of, or know someone with a stash of "known" good parts.
On the contrary, I am suggesting, as others have, the steps to economically find the problem.
