Wires Motorola Alternator

[windsmaker]

Wanting to hook an external Balmar voltage regulator to a
Motorola 9RC 7052 alternator that is on my Perkins 4 108 on my 84, Beneteau .

Where can I get a manual of this old 1984 Motorola alternator?

Anyone have any idea of the 4 wires that are on the Alternator Pictures that are enclosed.
# 1= red - positive , #2 - Black, # 3: blue ??? #4- Orange ??
which are the field and the static wires ?

How do I bipass the voltage regulator that is built to the alternator and hook up the ARS Balmar Voltage Reg.

thanks
