IMPORTANT - GUARANTEE AND INSTRUCTION This Replacement Unit will give you maximum service when properly installed. Regulators are guaranteed for ninetv days against defective workmanship and materials. Regulators are bench tested and set for correct charging rate according to original factory specifications. DO NOT TAMPER WITH ADJUSTMENTS. The fact that you are replacing the old regulator indicates the possibility that some trouble may exist in the electrical system that caused the old regulator to fail. To avoid damaging the replacement regulator follow these instructions carefully. Fig. I Fig. I1 Fig. 111

By L. V. LARSON

HE automotive electrical system actually contains two generators. CUTOUT CURRENT VOLTAGE T One is a chemical device that RELAY REGUUTCR REGULATOR produces voltage and current by chemical action and is called a stor- age battery. The other is a mechan- ical device which produces voltage and current when conductors arc forced to rotate through a magnetic field (Fig. 1) . In normal operation these two generators are hooked up so that the positive terminal of the battery and the positive terminal of the mechanical generator are con- nected together when the cutout re- AMMETER lay contact points are closed. In other words, the voltages of these Above, Fig. 1: The battery and generator are two generators normally oppose each the two electrical generators in the charging other, although this is not always circuit. Below, Fig. 2: Vibrating cutout relay recognized. contact points is one result of wrong polarity It is common practice, of course, to connect batteries and generators positive-to-positive and negative-to- negative, and it is assumed that cur- rent usually will flow into the bat- tery. It is this assumption which tends to hide the fact that these two units are opposing each other elec- trically. A review of important de- tails will help to clear up this point.

The voltage produced by a normal lead-acid storage battery is approxi- mately 2.1 volts per cell or 6.3 volts on a fully charged 6-volt battery on open circuit. The generator volt- age, on the other hand, is limited by a voltage regulator on which a limit setting of 7.4 volts can be considered normal. Under these conditions the maximum generator voltage is ap- proximately one volt higher than the open circuit battery voltage, and this difference in voltage will cause cur- rent to flow from the generator into the battery. When the battery is in Left, Fig. 3: Method of polarizing generators of the "A" circuit type. (Externally grounded field) Right, Fig. 4: Method of polarizing generators of the "B" circuit type.

GENERATOR-REGULATOR CIRCUITS Two different methods are used to connect the generator field circuit to the generator armature. the "A" circuit and the "B" circuit.
