Generator — removal and installation

Note: these cars are equipped with a 70A generator (at 12 V).

Removal and installation

Attention: when the battery is connected, between the car body and the terminal "IN" breakdown may occur. Doing so may result in personal injury, fire, or damage to the vehicle's electronic components. When removing the alternator, always disconnect the wire from the negative battery terminal.

1. Disconnect a wire from the negative plug of the storage battery.

2. Remove the parts in the order they are numbered in the figure "Removal and installation of the generator".



3. Installation of parts during assembly is carried out in the reverse order of removal.

4. Make sure that the deflection and tension of the alternator belt correspond to the nominal values (see chapter "Maintenance and general inspection and adjustment procedures").

Generator installation note

1. Lightly tighten the nut (A).

2. Tighten the fastening nut (IN).

• Tightening torque - 12-25 Nm

3. Adjust the tension and deflection of the accessory drive belt by turning the adjusting bolt (WITH).

4. Tighten nuts (A and B).

Vehicle check

1. Check the battery charge indicator.

A) Make sure the battery is fully charged.

b) Make sure that the deflection and tension of the alternator belt correspond to the nominal values.

V) Turn the ignition switch to position "ON" and check that the battery charge indicator lights up.

G) If this does not happen, check the circuit between the battery, the battery charge indicator and the corresponding terminals of the electronic control unit. Replace control unit if necessary.

d) Start the engine and check that the indicator is off. If it doesn't, check for trouble codes.

2. Check the voltage at the generator terminals.

A) Make sure the battery is fully charged.

b) Make sure that the deflection and tension of the alternator belt correspond to the nominal values (see chapter "Maintenance and general inspection and adjustment procedures").

V) Turn off all electrical consumers.

G) Turn the ignition switch to position "START" and check that the alternator rotates evenly and does not make any noise while the engine is running.

d) Measure the voltage between the generator terminals.



Table. Checking the voltage at the generator terminals




If the voltage is not as described, repair or replace the alternator.

3. Check the current at the generator outputs.

A) Make sure the battery is fully charged.

b) Make sure that the deflection and tension of the alternator belt correspond to the nominal values (see chapter "Maintenance and general inspection and adjustment procedures").

V) Disconnect the wire from the negative battery terminal.

G) Install an ammeter between the terminal "IN" and clamp.

d) Connect the wire to the negative battery terminal.

e) Turn off all electrical consumers.

and) Start the engine and set the engine speed to 2000-2500 rpm.

h) Measure the current at the generator output. Measurements are made on "hot" engine at an air temperature of 20°C and a voltage at the generator terminals of 13.5 V.

Current strength:

• at 1000 rpm - 0-55 A
• at 2000 rpm - 0-70 A

And) Switch on the following electrical consumers one after the other:

• headlights;
• heater fan motor;
• rear window heater.

To) Make sure the output current "IN" generator gradually increases. If the current does not increase, repair or replace the alternator.
