The function of the fuse is: when the circuit is faulty or abnormal, the current continues to rise. The rising current may damage some important or valuable components in the circuit, burn the circuit, or even cause a fire. If the fuse is installed correctly in the circuit, when the abnormal current rises to a certain height and time, the fuse will explode and cut off the current, thus protecting the safe operation of the circuit.

A car fuse is a kind of current fuse. When the current of the circuit exceeds twice the rated current of the fuse, it will fuse in a few seconds, thus playing the role of circuit protection. It is often used for overcurrent protection of automotive circuits and industrial equipment.

During the use of the car, if any electrical appliances do not work, it may be caused by a blown fuse, which needs to be replaced in time.

1. Turn off the ignition and open the safety box.
2. Replace the fuse.

Note:

(1) Replace the fuse according to the rated current value marked on the fuse box cover, do not use a fuse with a higher rated current.

(2) If the new fuse is immediately blown again, the circuit system may fail and should be repaired as soon as possible.

(3) There is no spare fuse. In case of emergency, the fuse can be replaced on other equipment that does not affect driving and safety.

(4) If you cannot find a fuse with the same current load, you can replace it with a fuse with a lower rated current than the original fuse.
