Fungsi Kabel Grounding Mobil Serta Ukurannya

Speaking of car grounding cables, this topic may not be unfamiliar to fans of classic car modifications. However, for fans of modern cars with advanced features, this may still be a foreign concept to them. So, what is meant by grounding cables in cars? What are their functions? Do they have a more specific size? For more details, please refer to the following review.

An Overview of Grounding Cables in Cars, Including Size and Functions

Grounding cables in cars are also known as mass cables. These cables are often used for modification purposes or to support the electrical system in classic cars.

These cables are usually connected from the negative terminal of the car battery to certain areas of the car. The purpose is to ensure that the areas connected to the grounding can produce the best quality negative electricity. This can enhance and maximize the performance of the car's electronic components.

Quality grounding cables can typically withstand high temperatures inside the car, especially around the engine area, which can reach 80 degrees Celsius to 90 degrees Celsius. Generally, grounding cables have a size of 10 mm square for NYAF type grounding cables. 

So, what is the function of grounding cables in cars? For more details, please refer to the following review.

1. Stabilizing the electrical current in the car's electrical system

The main function of grounding cables in cars is to stabilize the electrical current in the car's electrical system. As you know, the electrical system in cars can be quite complex. Why is that? Because the electrical system also plays a role in the car's performance and safety systems, such as the car's lighting components. Additionally, the electrical systems in older cars are quite vulnerable to functional decline. 

Therefore, it is necessary to add grounding to support the performance of the electrical system in classic cars. This way, the lighting system and electrical system in classic cars can function optimally, ensuring that the car remains comfortable and safe to drive.

This is very different from modern cars like the Daihatsu Ayla, Daihatsu New Xenia, and other latest models from Daihatsu. Daihatsu cars today can be considered modern vehicles equipped with advanced technology. Thus, Daihatsu cars already have a much better electrical system, eliminating the need for additional grounding cables. 

2. Facilitating the electrical inspection process in cars

Next, grounding cables can facilitate the electrical inspection process in cars. How is that possible? As you know, the working mechanism of grounding cables is supported by the negative battery.

Therefore, you should always regularly monitor the condition of the battery. Checking it is quite easy; you only need a testing tool to test the battery in general. You can check this component right next to the car battery. The inspection of the negative battery terminal can also be done easily, as the grounding cable is installed in that area.

3. Improving the safety of the car's electrical system

The location of the grounding cable around the car battery, especially at the battery terminal, keeps the grounding free from interference from other components. This can prevent electrical short circuits, making the car's electrical system much safer.

Thus concludes the review of the functions and sizes of car grounding cables. After reading this review, are you more interested in classic cars with added grounding, or are you more attracted to modern cars?
