Examination
You will need a multimeter to do the job.
1. We prepare the car for work (see "Vehicle preparation for maintenance and repair").
2. We check the electrolyte level and the degree of charge of the battery, if necessary, add distilled water and charge the battery (see "Battery - Maintenance").
3. Check the tension of the alternator drive belt and, if necessary, adjust (see "Alternator drive belt - adjustment and replacement").
4. We start the engine, use the carburetor air damper control knob to set the crankshaft speed to 2500-3000 rpm and turn off all consumers, except for the ignition system.
5. We measure the voltage at the battery terminals. If the voltage does not exceed 14.5 V, the regulator is working. In the event that the voltage is less than 13.9 V, it is necessary to check the contacts in the electrical circuit connections or the regulator is faulty.
Removing
1. Disconnect the wire from the negative terminal of the battery (see "Battery - removal and installation").
2. socket wrench by 8 mm unscrew the two nuts securing the regulator.
3. Marking or remembering the location of the wires, disconnect them from the terminals of the regulator.
Installation
The regulator is installed in the reverse order.
Attention! When connecting the wires to the regulator, do not mix them up. Incorrect connection will greatly increase the voltage in the mains, which will lead to damage to electrical consumers. Conclusion "15" orange wire is connected, and to the output "67" - grey (see "Electrical circuits").
