Ample Power 120A Alternator

Hi, I have a 1997 Hunter 430 fitted with an Ample Power 120A Alternator. There are four possible connections; the two main Posí and Negí posts, and a plug in lead with blue and white cables coming out.
Do you know if this is a Posí or Negí field control alternator? Iím guessing, since itís an American alternator itís likely to be positive field control. In this case itís also likely the Blue wire is the field control wire, am I correct?
If so, what is the white cable for?
The reason I am asking is that over the years the wiring has been bodged and itís hopeless to trying to sort it all out. I am replacing the Interchange Smart Regulator as it itís broken with a Sterling Power Smart Regulator via a Sterling Power 120A ProSwitch R. Finding the correct field control wire is critical.
Thanks for your help..

Balmar uses blue field and white stator (tach). So it would be a good guess.

FWIW: The “Ample Power Primer” includes wiring diagrams.
