| The battery does not hold a charge | The alternator drive belt is worn out or its tension adjustment is not correct (see chapter Routine car maintenance). |
| The electrolyte level has dropped excessively (see chapter Routine car maintenance). | |
| The battery terminals are oxidized, or the wire ends are loose (see chapter Routine car maintenance). | |
| The generator does not provide the required charging current (see chapter Ignition system). | |
| The wiring of the charging system circuit is broken or otherwise damaged, or the fastening of the terminals of the contact connections is loose (see Chapters Ignition system and On-board electrical equipment system). | |
| The battery is discharged due to a short circuit in the circuit (see Chapters Ignition system and On-board electrical equipment system). | |
| There is an internal battery defect (see Chapters Routine car maintenance and Ignition system). | |
| On some early models, the ignition/charge indicator lamp may burn out (see chapter Ignition system). | |
| The ignition/charge indicator lamp remains on after the engine has been started | The generator is faulty or there is a defect in the electrical circuit of the charging system (see chapter Ignition system). |
| The alternator drive belt is worn out or broken, or its tension adjustment is not correct (see chapter Routine car maintenance). | |
| The generator voltage regulator is not functioning properly (see chapter Ignition system). | |
