Battery Not Charging

OK, thanks you answered part of the question. What are you running for an alternator and regulator, and did it ever work, or is this a new build?

Also, non-factory wiring makes things difficult, how are we to realize how it is wired?

Your voltage measurements show only that it is not charging.

So once again is this a Mopar alternator or what? What regulator? you run the flat 70/ later or something else?

We cannot help you do anything except drink beer until we know what you are dealing with.
