I don't know if you have discovered that, whether we are on TV or in life, car fuses often have problems, and some safety films inside are often broken. And if it is broken, it will directly affect the correlation. If the operation of the entire system is serious, the vehicle will be turned off and cannot be used.

Car fuses are also fuses, and they have the same effect as fuses in your home circuit. However, its overall design is relatively small. Since the car battery uses a 12-volt battery, the power consumption is not as good as those of the induction cooker and air conditioner at home. However, the electrical equipment on the car is more complicated, so there are more safety film standards on the car. These safe tablets, which are more miniature than household safes, generally have different colors to distinguish the size of the value. When it comes to this mini, due to the complexity of the electrical equipment on the car, the current requirements are relatively strict. Generally, the car will set a threshold for the electrical circuit of each electrical equipment when planning, and match it with a suitable safe piece.

If there is a problem with the electrical equipment on the car and a short circuit occurs, the safety film will trigger a fuse under the impact of a short-term high current, which is used to alert the owner of the circuit failure and maintain the related circuit to reduce unknown losses. Generally speaking, it is normal for car fuses to fail. If the circuit of the whole car is faulty, it will be reflected in the consumption of the safety film first.

If some car owners modify some high-power electrical equipment, the safety chip may be frequently triggered to fuse. If you want a house, the fuse blown due to the installation of high-power electrical equipment needs to calculate the power and replace the safe sheet to the appropriate range. Generally, there will be spare safety chips in the safety film box on the car. If your car has a problem on the road, you can use these spare safety chips to make an emergency top, and then go to the repair shop for troubleshooting to avoid the circuit safety chip blown again.

Let's talk about several high-probability factors that cause the car fuse to be interrupted.

Change the car audio and headlights. Many car owners like to modify their car, especially the audio. They can't watch videos while driving, so let's listen to songs. Add some subwoofers to the car or something. There should be a lot of people who play with cars now. If it is directly modified, the original car audio instead of the installed so many time-related security lines have not been changed (can save some costs).

Washing the engine Now washing the engine has been accepted by many people. It's very simple to say, just seal all the lines related to the engine. But this is still very harmful for cars of a certain age (for example: Volkswagen cars, because there are more electrical circuits than Japanese brands, the failure rate is higher than that of Japanese brands). If the electrical circuit of a car is released, there will be more than 1000 meters, and the wire will age after a long time. A large pile of wires in the engine have arrived in the safe box (usually planned and hidden). When cleaning the engine, it is normal for some aging wires to be short-circuited and short-circuited. The older the car, the greater the chance of spontaneous combustion is also related to this factor.

Misuse of cigarette lighters The original intention of the cigarette lighter design is to light cigarettes. But now, car development has given him more functions, some of which are actually doing more harm than good. The fuse of the cigarette lighter designed in the original car is generally 10A. The cigarette lighter is used as the power supply. The external electrical equipment casually exceeds 10A, which causes the safety chip to fuse. In addition, the woodpecker master mentions that many car cigarette lighters are connected to the central control panel and even the air conditioning panel. The safety of the cigarette lighter is burnt, and the central control and safety will be finished. To emphasize again, if the car is safely interrupted, it is due to a problem in the line. It is not recommended to take a fluke and replace it with a usable one. The safety film is not expensive, but if there is a problem with the electrical equipment in the related circuit, it is not a problem with the car fuse.
