On some models, after operation, the breakers return to their original state automatically. If the overload that caused the tripping of the breaker was not episodic, the condition of the corresponding circuit should be checked without delay. After the fault has been cleared, the circuit breaker will return to normal operation. Sometimes the interrupter must be reset manually after the cause of the overload has been eliminated.
To activate the breaker, disconnect the negative cable from the battery.
Attention! If the stereo system installed in the car is equipped with a security code, before disconnecting the battery, make sure that you have the correct combination to activate the audio system! Remove the breaker, thread a thin rod into the specially provided hole in the housing and push it inside the hole until it clicks. Then it makes sense to use an ohmmeter to verify the presence of conductivity between the terminals of the breaker and only then install it in place.
