Alternators - Transistorized Regulator: Description

This unit is a fully transistorized voltage regulator using transistors and diodes to regulate the alternator field current and control alternator output. It is used optionally with the conventional double contact voltage regulator and can be identified on sight (see illustration). An adjustment is provided (40-ohm adjustable resistor on bottom of regulator case) by which regulator performance can be adjusted to provide correct operating voltages. This regulator is used with a conventional field relay (separate unit) and wiring is different on cars using an ammeter instead of a charge indicator light (see wiring diagrams).
