General description

The alternator of 37.3701 model is of AC, three-phase, clock-

wise rotation (when viewed from the drive end), with integral

diode plate and voltage regulator.

Protective cover 4 is used for slip ring-end housing (Fig.7-11).

The protective cover and air intake have several design alterna-

tives.

Four bolts hold together stator 21 (Fig.7-3) and housings 1

and 19. Rotor shaft 8 runs in bearings 6 and 18 located in the

housings. The rotor winding (field winding) is powered through

the brushes and slip rings 5.

Three-phase alternative current, induced in the stator wind-

ing, is converted into direct current in diode plate 2 fitted to hous-

ing 1. Electronic voltage regulator 12 is integral with the brush

holder and is also attached to housing 1.

The alternator wiring diagram is shown in Fig.7-4. When the

ignition is switched on, the voltage for the alternator actuation is

applied to the regulator terminal «Ç» (alternator terminal 61) via

warning light 6 in instrument cluster 3. Once the engine is start-

ed, the current to the field winding is supplied from three supple-

mentary diodes in the alternator diode plate.

The alternator operation is checked via warning light 6 in the

instrument cluster. The light comes on when the ignition is

switched on and goes out after the engine has been started,

when the alternator is good. Bright or dim light of the warning

lamp indicates faults.

Before 1995 an electronic voltmeter in the instrument cluster

was used to control voltage in the vehicle electrical system. With

correct voltage the voltmeter LED did not light up. In case of over-

voltage the LED started flashing, while in case of undervoltage

the LED stayed steadily.

Starting from 1996 an alternative voltage regulator and brush

holder are used. Now the voltage regulator is located in the metal

housing and is riveted to the brush holder (Fig.7-10, ‡), making a

unit. The new voltage regulator has no terminal «Å», so voltage

is supplied only to terminal «Ç». Both the earlier and new voltage

regulators are similar and are interchangeable as a complete unit

with the brush holder.

Some vehicles can be fitted with alternators made in

Slovenia, Bulgaria or Germany. These alternators are inter-

changeable with the alternator of 37.3701 model as to specifica-

tion and mounting sizes, though are slightly different in design.

This chapter describes the alternator of 37.3701 model, prefer-

ably used in VAZ-21213 vehicles.
