Folksvagen Sharan/Sharan repair>> Electric equipment>> The generator>> Generator repair
To make generator repair independently difficult and not expediently as for definition of its serviceability and conformity of its characteristics nominal the special stand is required.
Therefore repair of the generator is better for entrusting the qualified experts on HUNDRED firms "Volkswagen" where it is possible to replace also the generator from an exchange collection. Such generator on 50 % will be cheaper than the new. However before to change the generator, it is possible to spend following verifying works.
Check of a regulator of pressure on the car
For check of a regulator of pressure it is necessary to have the voltmeter of a direct current with a scale till 15-30 In, than a class of accuracy is not worse 1,0.
Check of a regulator of the pressure established on the car, spend in a following order:
- Start the engine and allow to it to work about 15 mines on average turns;
- By means of the voltmeter measure pressure between the plug 30 (the plug of a thick red cable on the generator) and "weight" of the generator;
- Pressure should be between 13,3—14,6 Century
In the event that it is observed regular недозаряд or recharge АБ and adjustable pressure does not keep within the specified limits, it is necessary to replace a pressure regulator. Besides it is possible to check up a condition of coal brushes.
Check of a condition of coal brushes
Though this work can be spent and at the established generator, it is recommended to remove the generator from the car nevertheless.
Check of a condition of coal brushes spend in a following order:

Fig. 334. Details of the generator and its fastening on the 2,0-litre engine: 1 — bolts М8, 25 Нм; 2 — a tension roller; 3 — an arm; 4 — натяжительное the device; 5 — nut M8, 30 Нм; 6 — a pressure regulator; 7 — bolts of fastening of a regulator of pressure, M4; 8 — a casing; 9 — bolts of fastening of a casing; 10 — the generator; 11 — поликлиновой a belt





- Turn away bolts 9 (fig. 334) fastenings of a casing see and remove a casing;
- Turn away two bolts of 7 fastenings of a regulator of pressure 6;

Fig. 336. A pressure regulator in gathering with щеткодержателем and coal brushes. It is necessary to measure, on what distance the ends of coal brushes act





- Cautiously take out from the case of the generator a pressure regulator in gathering with щеткодержателем and generator brushes (fig. 336);
- Measure length acting of щеткодержателя coal brushes. If their length is less 5 mm it is necessary to replace brushes.
The new coal brush has length of 13 mm, thus, it is possible to learn, coal brushes were how much strongly erased. Replacement of old coal brushes by the new means replacement of all regulator of pressure in gathering with brushes and щеткодержателем as coal brushes are soldered in in щеткодержатель. However at desire it is possible to address on HUNDRED Bosch for replacement only coal brushes. As in the car details Bosch this operation should not deliver any problems are established.
Trip with the faulty generator
If during a trip it was found out that the generator any more does not charge АБ (the control lamp of category АБ on a guard of devices constantly burns) it means that the generator does not develop pressure, or the chain of a control lamp of the category is faulty, or the electronic voltmeter is faulty. In the daytime it is possible to go within several hours (provided that АБ in a good condition).
In the present state of affairs carry out following recommendations:
- Whenever possible do not switch off the engine as at its restart the energy considerable quantity is spent;
- If nevertheless it is necessary to switch off the engine put the car under a bias that there was a possibility to start the engine, pushing the car under a bias;
- Switch off heating of back glass, a radio tape recorder and an oven;
- If there is not strong rain put screen wipers on a mode of faltering inclusion;
- If it is necessary to go to a night-time include only a passing light.
