1. If at ignition inclusion on an instrument guard of the car the control lamp of a charge does not light up, first of all it is necessary to check up reliability of fastening of plugs of electroconducting of the generator. If conducting is perfectly in order, check up, whether has fused an incandescent filament in a lamp, and also reliability of fixing in the panel of devices of its cartridge. If after the brought corrections the lamp on the former does not join, check up on presence of conductivity a wire of its food going to a cartridge from the generator. If the wire as it should be, hence, takes place internal malfunction of the generator and intervention of the expert is required.
2. If the control lamp of a charge continues to burn after start, or joins at the working engine, muffle it and check up correctness of adjustment of a tension drive a belt (address to the Head Routine maintenance). Make sure also, what not ослаб generator fixture. If everything is all right, the generator it is necessary to deliver for check and repair in a specialised workshop.
3. If there are suspicions on a deviation from norm of target pressure of the generator, despite serviceability of functioning of a control lamp, it is necessary to make qualitative check of a condition of a regulator of pressure (see further). At presence near at hand the necessary diagnostic equipment, it is possible to make check of the generator without its extraction from the car (see more low in separate subsection).
4. Connect the voltmeter to plugs of the battery and start the engine.
5. Lifting engine turns, achieve stabilisation of indications of the voltmeter.

The indication should make 12 ч 13 In, and not rise above 14 Century

6. Include as much as possible consumers of the electric power (head headlights, heating of back glass, the heater fan, etc.) and make sure that target pressure continues to remain at former level (13 ч 14).
7. The power failure at inclusion of consumers can be connected with deterioration of brushes of the generator, easing of their springs, failure of a regulator of pressure, malfunction of the diode, damage of a phase winding, or deterioration of sliding rings. The generator should be replaced, or is delivered for repair in a specialised workshop.

1. At presence near at hand a tachometre, the voltmeter, the ampermeter and shop of resistance, it is possible to collect the special measuring scheme and to make described below check of the generator without its extraction from the car.
2. Disconnect a negative wire from the battery.
3. Disconnect a wire of a winding of excitation from generator plug EHS. Also disconnect a giving wire зарядного a current from плюсового (+) a generator conclusion.
4. Connect the ampermeter consistently, and shop of resistance - in parallel in a chain зарядного a current (the Scheme of check of target parametres of the generator see an illustration). The positive pole of the ampermeter should be connected to the plug “+” the generator, negative - to the disconnected wire of giving зарядного a current. The shop of resistance joins between the negative plug of the ampermeter and weight.
5. Include the voltmeter in parallel in a category chain for what connect its positive plug to the plug “+” the generator, and negative - to weight.
6. Connect a negative wire to the battery.
7. According to instructions of manufacturers connect a tachometre.
8. Start the engine and leave its working on single turns. Make sure that frequency of rotation of the engine makes not less than 700 rpm and switch shop of resistance so that voltmeter indications have made 14 V.Znachenie of a current strength thus should be not more low 16 And.
9. Lift turns of the engine to value 900 in a minute, - the current strength should increase to 32 A.Dalnejshee increase of frequency of rotation of the engine (to 1800 rpm) should lead to increase of a current strength to 47 and.
10. Muffle the engine and disconnect a negative wire from the battery.
11. Disconnect all measuring devices and restore initial connection of electroconducting to the generator. Connect a negative wire to the battery.
12. Adjustable pressure can be checked up by means of the same scheme. Lift frequency of rotation of the engine to value of 1800 rpm and consider indications of devices. The pressure size should make 13.8 ч 14.5 In at a current strength in 42 And.
