Technical characteristics of the generator type 9402.3701-06
- Maximum recoil current at 14 V and 600 min, A - 85
- Limits of regulated voltage, V - 14.4-15.1
- Gear ratio engine - generator - 1: 2.4
Stator 10 (pic. 9.1) and covers 9 and 11 are tightened with four screws. The rotor shaft 16 rotates in bearings 3 and 13, which are installed in the generator covers. Power to the rotor winding (excitation winding) supplied through brushes and slip rings 4.
The three-phase alternating current induced in the stator winding is converted into direct current by a rectifier unit 1 attached to the cover 9. The electronic voltage regulator 7 is combined into one unit with a brush holder and is also attached to the generator cover 9.
The generator connection diagram is shown in fig. 9.2. The voltage to excite the generator when the ignition is turned on is supplied to the output «D+» regulator (conclusion «L» generator) via warning light 3 (see fig. 9.1) battery discharge located in the instrument cluster.
After starting the engine, the excitation winding is powered by three additional diodes installed on the rectifier unit of the generator.
Conclusion «W» generator is not used.
The operation of the alternator is monitored by a battery charging warning light located in the instrument cluster. When the ignition is turned on, the battery charging lamp should be on, after the engine is started, it should go out if the alternator is working. If the battery charging lamp lights up brightly or if it stays on, it indicates a malfunction.
