one wire Alternator and voltage regulator question

I don't know what alternator I had in it. It was one of those chromed "powermasters" but had the round style body and it had the field wire connected back to the VR when I bought the car. At that point there was a Petronix distributor but I swapped it out to the orange box and electronic Mopar Perfomance deal back in 2012. I left the VR in. About 2018 that alternator died. I had a local guy rebuild it but I think he left the spacer out of the middle and it ate itself up inside. (is that possible) anyway I bought this a new chrome powermaster with the squareback and the aforementioned guidance on the field wire delete. (which i have ignored) Let see its a 68 barracuda just like the one in my avatar with a 1971 340 and currently hooked up to a chrome box and an Accell coil. battery off it's at 12.54.

I have two VR mounted. (I had been alternating between them). I usually ran the blue one.
my ammeter always read 14 with my old set up and my fusible link wire was always HOT. After fixing some resistance points and the addition of a new alternator, that ammeter barely settles much above 12. (same gauge)
I'll work on the rest of the questions and read up on Mattax attached link in the morning.
