What's wrong with the Fox battery light?

I brushed a video a few days ago, which basically means: If the battery fault light on your dashboard is on, don't turn it on. It's important to save your life. Because this light is on, the generator does not generate electricity, or the generator belt is broken. The solution is to replace the belt or generator carbon brush. This video has millions of likes. From the media point of view, this video is an explosion. But for car owners, if you take this video seriously or even follow it, you will lose.

I simulated a circuit fault, unplugged the battery, and the battery fault light on the meter came on. But I still drove five kilometers and everything was fine. Let's make a scientific analysis. First of all, it's no problem to repair this faulty light as soon as possible, but it's a bit too much to tell everyone that life is in danger as soon as it comes up. It's not like a time bomb is about to explode. Even if the generator does not generate electricity, the remaining power in the battery alone is enough to ensure the normal operation of the vehicle for a period of time. It must be more than enough to drive to a nearby maintenance point.

Secondly, the real significance of the battery fault light turning red is that there is something wrong with the power supply system, and the pure mechanical fault of the generator not generating electricity is only a possibility. In addition, the failure of control module, wiring and even instrument panel may lead to battery failure light, so it is absolutely said that the generator is broken or the belt is broken. The correct way is to let the master of the repair shop look at the regional fault code first, and then analyze the specific reasons. Third, even if it is finally determined that the generator is broken, it is often impossible to change a brush in real life. There are two reasons. First, automobile generators are generally difficult to disassemble, and few repair shops are willing to change carbon brushes for you separately, so the operability is not very strong. Secondly, many automobile generators do not need brushless motors for a long time, but use brushless motors, which have smooth noise and low noise, and there is no carbon brush to replace them. So if you are the owner of the car, one day, the battery failure light is unfortunately on, and then you repair the car completely according to this video, I am afraid it is a joke.

With the popularity of small videos, you can often see various tips and tricks, and it is no exception in the automotive field. For example, I often brush until the so-and-so fault light comes on. Don't change anything, don't change anything, it's broken, as long as you do it, you can solve the problem. This kind of video is often loved by car owners, but this kind of dry goods video often has a feature that it is scrapped at first sight. Why? Let's talk about it today To tell you the truth, I made this little video, which was very painful to do. How can it be painful to make a small video for twenty or thirty seconds? As we all know, automobile products themselves are very complicated, and most technologies are non-standard. Different car manufacturers have different models, even the same model, different years, different configurations and structures may be different. And I'm a little obsessive-compulsive. I always want to tell everything when I make a small video, but it's really too difficult. Because a small video can give you dozens of seconds at most, you have to give up a lot of information. Finally, what really shows is that this may be a very extreme and one-sided view, and it must not apply to everyone, or the vast majority of people.

To tell the truth, cars are really complicated and developing with each passing day. Need to constantly update learning. Even for people with obsessive-compulsive disorder like me, every time I write a script, the content I shoot is still not comprehensive enough. Here, I would like to thank many friends who gave me comments or supplements. On the other hand, this firm idea of repairing cars undoubtedly consumes everyone's trust in network information step by step. Therefore, even as a self-media person who wants to convey dry goods and positive information, I still want to tell you that online video is still entertaining, including myself. Car owners should keep a good attitude when watching, knowing that many contents can't be complete and watertight, so how much they can refer to should be principled. This is why I know that long videos are tiring and not many people watch them, but I still insist on doing them at the same time, because I don't want everyone to just have fun. But I hope that our car owners in China can gradually understand cars and gradually form a more positive car culture.
