Not entirely (stated) correct. you can ground either field terminal on either a round or square "isolated field" and use them with the old regulator. I'm sure you know that LOL
Re read what I wrote you and I are saying the same thing. I outlined the 4 mopar alts 2 round 2 square. One round and 1 square are 1 wire field.
(Yes the square is a 2 field wire "isolated field" with one of the field wires grounded)
