If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

The details are as follows 


The following vacuum diagrams are representative of diagrams and components used in the emission control systems of these vehicles. Because there are many different make, model, engine, transmission, and calibration-level versions, there are many more vacuum diagrams than can be provided here.
Always consult the emission label under the hood for the most accurate vacuum diagram for that specific vehicle.
If the label is missing, contact your local VW dealer for a replacement.

Fig. Checking the alternators carbon brushes for wear
The voltage regulator is attached to the rear of the alternator and includes the brushes. Since no adjustment can be performed on the regulator, it is serviced only by replacement.
  1. Note the radio code, and then disconnect the negative battery cable.
  2. If the back of the alternator is not easily accessible, remove the alternator as necessary.
  3. If equipped, remove the cover on the back of the alternator.
  4. It is not necessary to disconnect any wiring. Remove the mounting screws and remove the regulator.
  5. Measure the free length of the brushes. If they are less than about 3 / 16 inch (5mm) long, the regulator must be replaced. New brushes are 1 / 2 inch (12mm) long.
  6. Install the new regulator and tighten the screws.
  7. The balance of assembly is in reverse order of removal.

This details will help.
Thanks.
