If the battery is discharged, then there's a secret consumer. It needs to be discovered. The first thing to do is to disconnect the minutes from the battery and connect the multi-meter between the terminals of the battery and the wire. If the device shows current, it goes from a secret consumer.
Then we need to connect the wire to the mass and pull one of the fuses out. If there's no current, the chain is fine. If there is a weak current, everything is also fine. There are consumers who constantly feed from the battery. For example, the computer computer or the clock.
The measurements must be repeated until the multimeter detects a strong current. According to the fuses table, it will be possible to identify on which network the secret consumer is located.
