The fuse holder in a car is an important component of the car's electrical system. Similar to the fuse holder in our homes, it serves to automatically melt and protect the circuit when the current exceeds its rated value. However, some improper actions by car owners can cause significant damage to the fuse holder. This article will introduce four behaviors of car owners that can damage the fuse holder.

Firstly, unauthorized installation of high-power headlights. Many car owners choose to install high-power headlights or xenon lights for better visibility at night. However, if the headlight power exceeds the original factory design or maximum load, the fuse holder will inevitably melt.

Secondly, installation of high-power audio systems. Many car owners modify their car audio systems for better sound quality. However, if the audio power exceeds the original factory design, the fuse holder will also melt.

Thirdly, washing the engine compartment with water. Many people like to keep their cars clean and tidy, but it is important to use the correct method when cleaning the vehicle. In the summer, some people use a water gun to wash the engine compartment, but this can easily cause a short circuit in the electrical system, leading to damage of the fuse holder.

Fourthly, using high-power electrical devices. There are many products on the market that use the cigarette lighter as a power source, such as navigation systems, chargers, and MP3 players. These low-power devices are generally not a problem, but inverters that can convert the 12V power supply of the cigarette lighter into 220V can consume a large amount of power and cause damage to the fuse holder.

Therefore, car owners should regularly check for cable damage or short circuits during daily driving. If the car breaks down on the road, do not immediately contact a tow truck for rescue. Instead, check the fuse holder first to see if it is damaged. Although the fuse holder in a car is small, it plays an important role in the car's electrical system. We hope this article will be helpful to car owners.
