Since 1988, a generator 37.3701 has been installed on VAZ-2105, 2104 cars (see fig. Generator 37.3701).
The connection diagram of this generator is given in subsection 12.15. The voltage for excitation of the generator when the ignition is switched on is supplied to the terminal "IN" regulator through the control lamp 11. After starting the engine, the field winding is powered by three additional diodes 3 installed on the rectifier unit. In this case, the current through the control lamp does not pass and it does not burn. The control voltage is applied to the output "B" controller directly from the terminal "30" generator. Conclusion "W" does not have a label. Brush 13 is connected to it (see fig. Generator 37.3701). The voltage in the vehicle's on-board network is controlled by a voltmeter 12 (see subsection 12.15).
Since 1996, the device of the voltage regulator and brush holder has been changed for the generator 37.3701. Now the voltage regulator is placed in a metal case and riveted to the brush holder (see snippet "A" in fig. Generator 37.3701), i.e. forms an inseparable knot with it. The new voltage regulator is missing a pin "B" and voltage is applied only to the output "IN". According to their characteristics, the old and new voltage regulators are the same and, assembled with a brush holder, are interchangeable.
Until 1988, the G-222 generator was used. It differed from the generator 37.3701 in the data of the rotor and stator windings, the voltage regulator and the 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 indicator lamp relay 11 was canceled, and the wires connected to the relay and indicator lamp were removed from the wiring harnesses. On these vehicles, the voltage in the on-board network of the vehicle was controlled only by a voltmeter 12.
On vehicles with a G-222 generator, in a circuit with a charge control lamp, a combination of instruments should be used, in which one end of the battery charge control lamp is connected to ground. Such instrument clusters were installed on cars until 1988.
