Individual fuse and relay elements can be installed outside this unit.

Some fuses don’t look like the ones you’re used to seeing in cars, but their functionality is the same. Conventionally, they can all be divided into fuses and automatic ones.

Checking the fuse

  1. Remove the fuse from the module using pliers and visually inspect it.
  2. If the fuse wire is blown, replace the faulty fuse with a spare fuse.
  3. Turn on the electrical consumers and check their operation. If the fuse blows again, contact a specialized workshop with qualified personnel to check the electrical equipment.

Checking the circuit breaker

When the circuit breaker trips, the pin (4) moves to the off position (2).

  1. Remove the circuit breaker from the module.
  2. Push the pin (4) into the on position (1).
  3. Press the release button (3).
    – If the pin (4) moves to the off position (2), the circuit breaker is OK.
    – If the pin (4) does not move to the off position (2), the circuit breaker needs to be replaced.
  4. Press the pin (4) into the on position (1) and reinsert the circuit breaker.
  5. Turn on the electrical consumers and check their operation. If the circuit breaker trips again, contact a specialized workshop with qualified personnel to check the electrical equipment.
