Matters needing attention in automobile electrical and electronic maintenance

At present, high-tech is widely used in cars, and its development direction is electromechanical integration. The development of microelectronics has further promoted the development of automobiles in the direction of electronic control, making automobiles safer, more economical, better handling, and pushing the performance of automobiles to a higher level.

At the same time, car maintenance work has become easier and more difficult. Because the car is usually equipped with an electronic self-checking system, if a certain system fails, it can automatically remind the driver to repair it in time, so that it can prevent accidents and can be quickly detected with special instruments, so it is said to make maintenance work easier . On the other hand, it requires maintenance workers to have corresponding high-tech knowledge and special testing equipment, otherwise they will not be able to start. From this perspective, it becomes more and more difficult to maintain modern cars.

For the traditional automotive electrical parts, it is mainly the maintenance of batteries, spark plugs, generators and other components.

If the battery is not used for a long time, it will slowly discharge itself until scrapped. Therefore, the car should be started at regular intervals to charge the battery. Another method is to unplug the two electrodes on the battery. When pulling out the positive and negative electrode wires from the electrode column, first pull out the negative electrode wire, or remove the connection between the negative electrode and the car chassis. Then unplug the other end with the positive sign.

The battery has a certain service life and will be replaced at a certain period. The same sequence must be followed when replacing, but when the electrode wires are connected, the sequence is reversed. Connect the positive electrode first, then the negative electrode.

The storage capacity of the battery can be reflected on the dashboard. When the pointer of the ammeter shows insufficient storage capacity, it should be charged in time.

The generator is generally not easy to damage, mainly because the tightness of the belt between the generator and the engine should be checked frequently. If the belt is loose, it will slip, causing the generator to not rotate; in addition, it is to check the two carbon brushes on the generator, and they must be replaced to a certain extent.

Unclean fuel will gradually deposit carbon or grease between the two electrodes at the end of the spark plug, weakening the spark between the two electrodes, and the output of the engine will decrease. So after using for a period of time, the spark plug should be removed to remove the dirt on the upper area. In addition, it should be replaced regularly according to the provisions in the manual.

In order to protect the car and prevent the electrical parts from being damaged by electrical circuit faults, there is a fuse box on the car, and each internal fuse is connected to a corresponding electrical circuit. Therefore, when a certain part of the electrical appliance fails, first check whether its fuse is broken. If it breaks, replace the fuse. If it is burned again, it indicates that there is a short circuit or other damage in the system, and it must be sent to the auto repair shop for repair immediately. At the same time, it should be noted that the allowable current of the fuse of each system is different, and the same specification must be used when replacing. Experienced drivers usually carry some fuses of the corresponding type in the car in case they are needed in case of unforeseen circumstances. Similarly, if you often drive at night, it is sometimes useful to bring some corresponding bulbs.
