Alternators with INTERNAL REGULATOR:
See below for various wiring diagram for alternators with internal regulator:
The field circuit wire on alternators with internal regulators is located within the alternator housing and it is impractical to use the field disconnect
feature. Protection of the alternator diodes can be achieved by installing a Guest Isolator #2401A (for 70 ampere alternators) or other appropriate
model.
