Alternator Outputs

[FOT Fast]

Bought 130 amp Mustang alternator from Real Steel but no-one seems to know what the wiring diagram is??

Anyone know what the following Alternator outputs might be……3 pin connector A, S (or B it’s hard to read) and the I terminal......then a single wire connector with no label and finally the large positive battery terminal. I’ve tried the web but there’s nothing out there!!!


Help!!

According to the notes I took when in Ford school:

A = power from battery to field, acts as a sensing circuit.
S = sends A/C voltage to control the charging lamp in the instrument pack.
B = source voltage (battery)

I = power from ignition switch through the charging lamp, also wakes up the voltage regulator.

Here is a diagram from my study guide, please excuse my scribbles..:
