Note: Electronic control system diagnostic procedures and trouble codes are listed in Chapter 5.
17. There is a decrease in capacity or insufficient battery power
1. The alternator drive belt is worn or damaged, or its tension is not adjusted.
2. Insufficient electrolyte level.
3. There is corrosion of the battery terminals, or the fastening of the wire lugs on them has loosened.
4. The generator does not provide the required charging current.
5. Broken or otherwise damaged charging circuit wiring, or loose wires at the terminals.
6. There is a short circuit in the electrical wiring, creating a constant leakage of current generated by the battery to ground.
7. There is an internal defect in the battery.
18. The charge indicator lamp does not go out after starting the engine
1. Loose/worn alternator drive belt.
2. Loose fastening of the contact terminals of the generator wiring.
3. There is a short circuit in the control lamp power circuit.
4. Damaged stator or generator diode assembly.
5. Faulty voltage regulator. Disconnect the wire (D+) on the reverse side of the generator and turn on the ignition - if the control lamp does not light up, check the condition of the voltage regulator.
6. Worn carbon brushes.
7. The wire between the generator and the voltage regulator is damaged.
8. Faulty instrument cluster.
19. The charge indicator lamp does not light up when the ignition is turned on
1. Burned out or otherwise failed the actual K / L on the instrument panel.
2. The generator is faulty.
3. There is a defect in the printed circuit board or wiring inside the instrument cluster, or the lamp socket is damaged.
4. The corresponding fuse is knocked out (in the presence of).
5. There is a short circuit in the electrical wiring in the generator.
6. Faulty alternator rectifier bridge.
20. The charge indicator lamp does not go out when the ignition is turned off
1. Broken diodes.
