Charging System Question

63 Dodge Dart with 225 slant 6 and stock electrical system. This is the little car I am pretty much working on for free to help a nice young man after his car was vandalized really badly. It had a behind the cluster electrical fire. I have repaired everything that I can find. The alternator is not charging. I know enough about this stuff to get in trouble. lol

Now, since my repairs, the ammeter is working. It shows a slight discharge when the ignition is turned to run. Slightly more with the engine running. I have continuity from the big red alternator wire TO the positive post of the battery. I get battery voltage at the alternator post going to ground. I have a dual field square back alternator that I grounded the second field terminal on.

Months ago, when I installed the alternator, it was charging AT the alternator. In other words, when I went from the bit terminal to ground, I got "around" 14.5V. It however was not getting TO the battery, because of the crispy wires behind the cluster. It has a new BW voltage regulator. Yes, I know new ain't the same as good.

I grounded the field terminal that goes to the regulator. No change. I've tried two other alternators.....don't know if they're good.....it looks like I'd at least "get lucky" with one, but who knows? At this point, I am thinking the "new" alternator might be bad. I did take the voltage regulator off and neither coil is burned and I get resistance on the DVOM instead of an open circuit, so my thinkin is the regulator is good.

Can somebody stupid it up for me here? I would much appreciate it and I know James would too. I would love to give him his car back with the charging system working. @67Dart273 @Mattax What say you fellers? Thanks.
