How about car circuit repair how to repair car circuit repair

If you learn the car circuit well, the future is really unlimited 1, now the mechanical fault is all with the replacement assembly, maintenance is very simple 2, the power problem is the most difficult problem in the 5S shop, because the fault cause is difficult to find 3, and now the car repair workers have low education, and the good repair is all based on years of experience, but can understand the circuit diagram, can understand the circuit is really few. 4. Only the technical director in our store can really understand the circuit diagram and repair it, not to mention the salary, I think learning the car circuit is very developed, not so tired, and the technical content is very high.

If you want to learn automotive circuits well, you must first learn the basics of electrician and electronic technology. Because no matter what kind of circuit it is, its basic principles are inseparable from the most basic knowledge, such as Ohm's law, electronic amplification, control, circuit and other principles. Some people always want to take shortcuts, and that kind of transformation will only draw a scoop according to the gourd, and they will be blind when they encounter difficult problems.

For example, if the turn signal is not lit and there is no basic knowledge, you can only change it from the bulb, switch, and controller one by one until it is normal. If you have basic knowledge, you can basically analyze what part of the fault is from the phenomenon of failure. In particular, some modified line faults can better reflect the level of repair personnel when analyzed.

At the beginning of learning automobile circuits, first know how many electrical appliances are installed in the car, what they are for, and then figure out the intermediate links associated with each electrical appliance. For example, the roof light circuit in the car: the power supply passes through the fuse to one end of the dome light bulb (electrical appliance), and the other end of the bulb is divided into two ways, one is connected to the top light switch, and the other goes to the door switch; The other end of the dome light switch and the door switch are respectively mounted on the iron, so that two states controlled by the dome light switch are formed, and the top light is on when the door is opened, and it can also be controlled after the door is closed.

When you understand each single circuit, you have the conditions to learn the basic principles and working conditions of automotive electrical appliances, learn the correlation between the circuit and the circuit, and analyze the possible faults of the circuit, otherwise it will be very empty and tiring to learn.

Be patient. Repairing the car circuit is a fine job, the wiring harness is only a little damaged, which will cause the car electrical appliances to not work normally, so we must be careful and patient when overhauling the circuit, so as to find out the problem.

Understand circuit diagrams. Automobile manufacturers will issue circuit maintenance manuals for their after-sales departments, and there are also books on the market that sell automotive circuits, so you must learn to understand the automotive circuit diagram, encounter circuit problems, and quickly find the fault point according to the circuit diagram.

Master the basic characteristics of automotive circuits. For example, there are two power sources in the car, the car itself is a tie point, and the electrical equipment on the car is connected in parallel, low-voltage direct current, and Ohm's law is known.

Proficient in the use of multimeters and test lights. When repairing the car circuit, the voltage and current in the line are often measured, if the maintenance technician does not know how to use the multimeter, the car circuit can not be repaired, of course, the test light is also a good circuit maintenance tool.

Communicate with your peers and learn more. Threesome, there must be my division, the same fault, handed over to different technicians to repair, there will be different maintenance process, this process is the maintenance of ideas, the comparison of their own ideas with others, you can see the difference, choose the best method experience, your own technology has a great improvement.

Summarize and write notes. In the process of overhauling the circuit, when encountering a more classic case, it is necessary to write it down through notes, and as the number of notes increases, summarize the circuit problems of a system, and look at the notes in your spare time, so that you can review the old and learn the new, and greatly improve your own technology.

Repairing car circuits is a delicate job, and you must be careful and patient. To learn to understand the car circuit diagram, when encountering circuit problems, you can quickly find the fault point according to the circuit diagram. Master the basic characteristics of automotive circuits.

Proficient in the use of multimeters and test lights. Learn more from experienced teachers and summarize by yourself.

It's the age of the web. As long as anyone can publish their works on different platforms in compliance with the regulations, the level of knowledge is uneven, and it is inevitable that they will be mixed. If it's entertainment or funny, we'll laugh a lot, but knowledge sharing is different, because knowledge is very rigorous, and sometimes a mistake or mistake can make a big difference, causing a lot of losses.

Because any platform will not spend a lot of manpower and material resources to accurately check the rights and wrongs of each knowledge content, nor will it be rejected because of someone's mistake or explanation error, unless it is too outrageous, so we still have to study carefully and selectively when learning knowledge content, because everyone on the platform cannot be a professionally trained teacher or lecturer or trainer.

Take, for example, automotive circuit repair. Nowadays, many maintenance workers or electricians like to take some cases of their own maintenance, such as measuring the voltage, current, temperature, etc. of a sensor or actuator. Some use power test lights, and some use multimeters, oscilloscopes, diagnostic instruments and other equipment.

It doesn't matter what equipment you use, it's important to master the measurement method. If the measurement method is incorrect, the measurement will be wrong, or the measurement will not be the result you want, and the computer board or control module will be burned out in serious cases. Some of them are not even thorough in principle and are still teaching others how to measure, and some are power indicators made by themselves, which are called "car repair artifacts" and so on.

Of course, circuits are very flexible, and everyone's diagnostic ideas and methods may be different, so they have their own unique skills and tricks. However, care must be taken when measuring computer-controlled wiring harnesses with a power test lamp. Before understanding the control circuit, do not let one end of the power test lamp be connected to the positive power supply, and the other end pokes the ** beam, which is easy to burn the computer board, and it will burn more than one computer board.

So sometimes many failures are man-made failures caused by improper operation, which not only wastes the customer's time, but also makes the customer pay for the final loss. This phenomenon is common in repair diagnostics. What's more, we deliberately set up a fault line in order to shoot a **.

Finally, through a series of tests, the fault was finally found, which showed our high level, and finally won everyone's attention and obtained the best amount. Regardless of the purpose, maybe it's a marketing ploy, and there's nothing wrong with it, because the platform is fair to everyone.

Finally, to sum up, the platform provides each of us with an empty space to play. Each of us can also give full play to our talents on the platform and share the fruits of others' labor to improve our knowledge and ability. But no one is perfect.

Everyone makes mistakes. Sometimes, we really don't know what we're wrong. At this time, you must be cautious in acquiring knowledge.

We should choose to accept knowledge that is useful to us. Don't blindly accept what others say, even be cut leeks, and cheer for it.

Millions of car purchase subsidies.

1 The power supply is limited to the wire of each electrical fuse or switch is the common front of the electrical equipment. In the circuit schematic, it is generally drawn on the upper part of the circuit diagram.

Circuit diagram of the 2-track model drawing method, where the contacts of the switch are located at zero or dynamic. That is, the switch is in the disconnected state or the relay coil is in the unenergized state, and the conduction and cut-off of components with switching characteristics such as transistors and thyristors depend on the full house.

3. The characteristics of the automobile circuit are dual power supply, single-wire system, each electrical appliance is connected in parallel with each other, and the relay and switch are connected in series in the circuit.

4. The most limited electrical equipment is passed through the fuse and cherished by the fuse.

5. The circuit of the whole vehicle is divided into a number of independent circuits according to the effectiveness and principle of the matter. In this way, it can solve the problem of the title of the huge and chaotic circuit of the whole vehicle and the complicated analysis. Nowadays, the automobile circuit is generally drawn according to the preparation of each circuit, such as power system, engine system, ignition system, lighting system, signal system, etc., these unit circuits have their own characteristics, grasp the characteristics of the layout and principle of each unit circuit, and understand the vehicle circuit is easy.
