Since 1988, the VAZ-2105, 2104 vehicles have been equipped with the 37.3701 generator (see Fig. Generator 37.3701).
The connection diagram of this generator is given in subsection 12.15. The voltage for driving the generator when the ignition is turned on is applied to the terminal "B" of the regulator through the control lamp 11. After starting the motor, the field winding is powered by three additional diodes 3 installed on the rectifier unit. At the same time, the current does not pass through the control lamp and it does not light up. The control voltage is applied to terminal "B" of the regulator directly from terminal "30" of the generator. The output "W" of the regulator is not marked. The brush 13 is connected to it (see Fig. Generator 37.3701). The voltage in the vehicle's on-board network is monitored by a voltmeter 12 (see subsection 12.15).
Since 1996, the 37.3701 generator has had its voltage regulator and brush holder changed. Now the voltage regulator is placed in a metal housing and riveted to the brush holder (see fragment "a" in Fig. Generator 37.3701), i.e. forms a non-separable unit with it. The new voltage regulator does not have terminal "B" and voltage is supplied only to terminal "B". According to their characteristics, the old and new voltage regulators are identical and are interchangeable when assembled with the brush holder.
Until 1988, the G-222 generator was used. It differed from the 37.3701 generator in the rotor and stator winding data, voltage regulator and brush assembly, as well as the design of the rectifier unit. The connection diagram of the G-222 generator is given in subsection 12.16.
In 1985, the control lamp relay 11 was cancelled, and the wires connected to the relay and control lamp were removed from the wiring harnesses. On these cars, the voltage in the vehicle's on-board network was monitored only by the voltmeter 12.
On cars with a G-222 generator, a combination of instruments with one end of the battery charge control lamp connected to ground must be used in the circuit with a charge control lamp. Such combinations of instruments were installed on cars before 1988.
