Hello Folks,
putting this alternator into an old machine but cannot figure the wiring.
No marks or indications on the alternator only "B" which is obvious anyway as its the power output post. Need to know which is the "exciter" terminal and which is the "voltage sense" terminal. And whats the wire which comes out through the casing.
Appreciate the help,
John
