Couple alt/reg questions

Have a read, the mechanical setup does control alt output by means of lower/raising currant to the single 'green' field terminal, so yea hooking full voltage from the batt post will cause full output @2000rpm+

but on the dual field style you just ground the 2nd field 'blue' and the alternator will full output, because the new style regulator controls the ground to the alternator.

I understand that, and have understood that since the early '70's. What is in conflict with this and what I wrote?

It looks to me like you changed your original post??

If so, then what I wrote referred to that, and not what is currently on the board.

While I agree that the newer alternator and regulator is a "better deal" I resist the urge to "just go out" and buy the new stuff, and engage in a bunch of rewiring, which may make finding the original problem more difficult.

TROUBLESHOOT the problem first, THEN decide if you want to upgrade as part of the fix. Hell, with all the talk about "Denzo's" 'n stuff, I'd be tempted to not even run a Mopar alternator. I ran Delco's back in the 70's after I rattled a couple of Mopar units to death.
