Removing
1. We prepare the car for work and disconnect the wire terminal from the negative terminal of the battery («Preparing the car for maintenance and repair»).
2. Disconnect the wiring harness block from the generator.
3. Remove the protective rubber cover and use a 13 mm socket wrench to unscrew the nut that secures the wire lugs to the terminal «B+» generator.
4. Remove the tips of the two wires from the contact bolt.
5. We release the three spring clips for fastening the casing of the rectifier unit (shown on removed alternator) and remove the cover from the generator.
6. Disconnect the voltage regulator wire block from the output of the rectifier unit.
7. Using an 8 mm socket wrench, unscrew the two bolts securing the voltage regulator.
8. With a 12 mm open-end wrench, unscrew the nut of the contact bolt.
9. Disconnect the output from the contact bolt and remove the voltage regulator.
Installation
Install the voltage regulator in the reverse order of removal. Before installing the voltage regulator, which is in operation, we inspect the brushes, make sure that they are mobile. If the brushes are broken or badly worn (protrude from the brush holder by no more than 5 mm), or they are wedged in the brush holder, the regulator must be replaced.
