10.5.1. Features of a design
On Chery Amulet cars establish the generator of an alternating current, three-phase, with the built-in vypryamitelny block and an electronic regulator of tension, the right rotation (if to take a detached view a drive).
|Fig. 10.6. Generator details: 1–casing; 2–shchetochny knot; 3–tension regulator; 4–vypryamitelny block; 5–coupling bolt; 6–insulator of conclusions of a winding of a stator; 7–back cover; 8–back bearing of a rotor; 9–nut of fastening of a pulley; 10-spring washer; 11-pulley; 12-forward bearing of a shaft of a rotor; 13-forward cover; 14-stator; 15-rotor; 16-contact rings
Stator 14 (fig. 10.6)
and covers 7, 13 are pulled together with four bolts 5. The shaft of a rotor 15 rotates in bearings 8 and 12 which are established in covers. A food is brought to a rotor winding (an excitement winding) through brushes and contact rings 16.
The three-phase alternating current induced in a winding of a stator, will be transformed in constant by the vypryamitelny block 4 attached to a cover 7. An electronic regulator of 3 tension and a shchetkoderzhatel 2 also fasten to a cover 7. Tension for generator excitement at inclusion of ignition is brought to a conclusion «by D +» a regulator through an alarm lamp of the category of the storage battery, located in a combination of devices.
After engine start-up the winding of excitement eats from three additional diodes established on the vypryamitelny block of the generator.
Operation of the generator is traced by an alarm lamp of the category of the storage battery located in a combination of devices. At ignition inclusion the lamp should burn, after engine start-up – to die away, if the generator is serviceable. Bright burning of a lamp or its burning dimly testifies to malfunctions.

Recently there were many firms specializing on repair of import starters and generators. There it is possible to carry out diagnostics of faulty knot, to get spare parts for any model of the generator (starter), to receive the qualified consultation. If you are not sure that can repair the generator (starter) independently, there is a sense to address in such firm where repair of these knots will execute quickly, qualitatively and for reasonable price. However on cars to big run often happens more favorable to replace knot assembled new, than to replace the failed details.
