Currently the car uses a lot of high-tech, its direction is mechatronics. Microelectronics promote the development of more electronic vehicle development to control the direction, making the car safer, more economical, and better handling, the car's performance to a higher level. At the same time, vehicle maintenance and repair work has become both easy and more difficult. Because the car is usually equipped with an electronic self-test system, a system fails, it can be repaired automatically alert the driver of the car battery manufacturers, car battery so you can take preventive measures, with special instruments can be quickly detected, and therefore it make repairs easier. On the other hand, it requires maintenance workers must have the appropriate high-tech knowledge, and there are special detection equipment, otherwise it can not start. From this point of view, it is more modern car repair difficult. For traditional automotive electrical parts, the main maintenance batteries, spark plugs, generators and other components. Because batteries are now commonly used lead-acid batteries, sulfuric acid liquid overflow easily, and sulfuric acid is highly corrosive, so be promptly wipe clean, taking care to not touch the eyes and skin. Sulfuric acid contained in the water will evaporate when the top surface of the liquid sulfuric acid near the stereotype, it is necessary to add distilled water. Of course, a lot of cars have adopted a maintenance-free battery, because the whole enclosed in a plastic case, reducing the maintenance workload. Batteries do not long, it will slowly self-discharge, until retirement. Therefore, at regular intervals should start a car, to charge the battery. Another option is to pull the two electrodes on the battery down, pay attention to unplug from the positive electrode column, minus two electrodes line, first disconnect the negative cable, or remove the negative and the vehicle chassis connection. And then pulling the other end with a positive mark. Generator is generally not easy to damage, mainly should always check belt tension between the generator and the engine. Loose belt will slip, causing the generator does not turn; moreover, is to check the generator on two carbon brush wear to a certain extent to be replaced. Spark plug unclean fuel will gradually between two electrodes of the spark plug ends owed coke residue or grease, the spark between two electrodes weakened, engine power output will drop. So, after a period of use to the spark plug removed, remove accumulated dirt above. In addition, it should be in accordance with the instructions on the periodic replacement. Fuse to protect the car, so that the electrical part of the fault is not due to electrical lines and burn electrical components, the car has a fuse box, a fuse inside each and are connected to an appropriate electrical circuit. Therefore, when a part of the electrical failure, first check the fuse if it is broken. If broken, replace the fuse. If you blow again, it shows that there is a short circuit or other damage to the car battery What makes a good, must immediately send garages overhaul the system. Note also that each system allows the amount of current the fuse is different, be sure to use the same specification when replacing. Experienced drivers usually are in the car with some type of fuse corresponding car battery, when it needs to prepare for any eventuality. Similarly, if often driving at night, take some appropriate bulb, sometimes useful. Car battery is dead how to do, car battery, car battery, Wei Li Po provided by Shenzhen Wei Lai Po Battery Limited.
