The most common causes of fuse failure in the car

The most common causes of fuse failure in the car


    The car contains many fuses, and the fuses are characterized by protecting the electrical circuits in the car from exposure to weather factors; As it controls the electric currents passing through the wires, if the car is not equipped with fuses, the overload of the electric current may lead to a high temperature of the wires, and fire, but sometimes the fuse may have some malfunctions, and in this article, we will review the causes of the fuse malfunction The most important signs by which one can know that the fuse is in malfunction, and how to fix it.

1. Short circuit

The exposure of the electrical circuits inside the car to an electrical short can lead to a fuse failure, and the reason for this is the high temperature of the wires or their melting, and the reasons for the occurrence of an electrical short within the electrical circuits can be summarized as follows:
  • damage to the wires that make up the circuit; If one of the wires that make up the electrical circuit is worn out, or exposed, it can touch the surrounding metal frame or the ground, and this leads to an electrical short and fuse damage.
  • There is a malfunction in the electrical systems inside the car; When there is any malfunction in the electrical systems, such as a malfunction in the system responsible for the windshield wiper, or other systems, this leads to an increase in the load on the electrical circuit, the occurrence of an electrical short, and damage to the fuse.
  • Leaks anywhere inside the vehicle; When there is any leakage inside the car, this may reach the electrical wires and cause damage, and this leads to an electrical short, damage to the electrical circuit inside the car and damage to the fuse.

2. Using inappropriate fuses

    When choosing the right fuse for the car, care must be taken to ensure that it is suitable for the electric current inside the car and that it is made of good quality materials. To ensure that the fuse used is suitable for the vehicle.


How to fix broken fuses

    The best solution when the fuses fail is to change them, but care must be taken to ensure that the quality of these fuses is identical with the fuses to be changed, and the amount of energy that the fuses bear is proportional to the energy in the electrical circuits inside the car, and a specialist can be hired to change them, It can be changed without resorting to a specialist if you have knowledge of installing fuses, but care must be taken to wear protective gloves and use special tools and equipment to protect against electricity while changing fuses.
