Note. Please refer to the warnings contained in the paragraph 1 of this chapter.
1. If the warning light does not light up on the display when the ignition is turned on "battery", first of all, check the wiring of the generator and its connection. If everything is in order, check if the light bulb has burned out and its cartridge is correctly installed on the board. If the bulb still does not light up, check the continuity of the wire from the alternator to the bulb holder. 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. Carry out all these checks and, if no damage is found, seek expert advice.
3. If the light bulb "battery" lights up when the engine is running, stop the engine and check the tension of the alternator drive belt (see chapter 1A or 1B) and integrity of the electrical connections of the generator. If there is no doubt, check the condition of the alternator brushes and armature slip rings as described in paragraph 6. If the problem persists, have an auto electrician check and repair the alternator.
4. If there is a suspicion that the output voltage of the generator does not match Specifications, even if the emergency light "battery" functions as expected, you can check the mains voltage as follows.
5. Attach a voltmeter to the battery terminals and start the engine.
6. Increase the engine speed until the voltmeter reading stops changing. The voltage at the battery terminals must 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 hung brush springs, a faulty relay-regulator, a breakdown / open circuit in the diode blocks, a malfunction of the generator windings or corrosion, damage to the rotor rings, or additional, too powerful current consumers ("chandelier", amplifier for 5 kW RMRO). The alternator must be replaced or an auto electrician checked and repaired.
