Note: Before you begin the operation, please refer to the warnings contained in paragraph 1 this chapter.
1. If the "battery" warning light does not light on the dashboard when the ignition is turned on, first check the generator wiring and its connection. If everything is in order, check whether the bulb has burned out and whether its socket is installed correctly on the board. If the bulb still does not light, check the integrity of the wire from the generator to the bulb socket. If the wire is intact, then the generator is faulty. It must either be replaced or given to an auto electrician for inspection and repair.
2. If the light comes on when the ignition is turned on, but does not go out immediately when the engine is running, there may be load problems in the generator. Perform all these checks and, if no damage is found, seek advice from a specialist.
3. If the "battery" light is on when the engine is running, stop the engine and check the tension of the alternator drive belt (see chapter 1A or 1B) and the integrity of the electrical connections of the generator. If everything is in order, check the condition of the generator brushes and the slip rings of the anchor as described in paragraph 6. If the problem persists, contact an auto electrician to check and repair the generator.
4. If there is a suspicion that the generator output voltage does not correspond Specifications, even if the "battery" warning light is functioning as it should, you can check the voltage in the network as follows.
5. Connect the voltmeter to the battery terminals and start the engine.
6. Increase engine speed until the voltmeter readings stop changing. The voltage at the battery terminals should be within 13.V...14.2 V.
7. Turn on all possible current consumers and make sure that the voltage at the battery terminals does not drop below 13.2 V.
8. If the voltage value is outside the above ranges, the cause may be worn brushes or their springs hanging, a faulty relay regulator, breakdown/break in the diode blocks, faulty generator windings or corrosion, damage to the rotor rings, or additional, too powerful current consumers are turned on ("chandelier", 5 kW RMRO amplifier). The generator must be replaced or an auto electrician must be instructed to check and repair it.
