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.
2. The circuit diagram of the rail model drawing method, the contact of the switch is located at the zero position 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 and 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 electrical equipment with large limitations has passed through the fuse and is cherished by the fuse.
5. The vehicle circuit 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.
Extended InformationIn electricity, the loop is the most basic, the most important, and the simplest concept, any complete circuit is composed of power supplies, electrical appliances, switches, wires, etc. As far as the DC circuit is concerned, the current always has to go from the positive pole of the power supply, through the process wire, fuse, switch to the electrical appliance, and then through the wire (or tie) back to the negative pole of the same power supply. For example:
How long does it take to drive from the positive pole of the power supply and learn car maintenance. After a certain electrical appliance (or other electrical appliances) returns to the positive pole of the same power supply, because the potential difference (voltage) of the power supply only lives between the positive and negative poles of the power supply, the same electrode of the power supply is equipotential and has no voltage. This "positive to positive" path does not present currents.
In automotive circuits, generators and batteries are both power sources, and when looking for circuits, they should not be mixed up and driven from the positive pole of a power source. After passing through a number of electrical devices, it returns to the negative pole of another power supply, which is practiced. There will be no real pathway, and no electric current will appear.
Take a look at automotive circuit repair training. Therefore, it is necessary to exaggerate that the circuit refers to the positive pole of a power supply, passing through the electrical appliance, and returning to the negative pole of the same power supply.

**There are auto repair schools, which are regular auto repair schools for analysis:
First, it is recommended to go to the school for a field trip.
1. Look at the brand of the school, choosing a good brand of auto repair school is an important factor in choosing a school, and the brand is a symbol of quality, representing the comprehensive strength and quality of the auto repair school. Generally speaking, the teaching quality of auto repair vocational schools with excellent brands is relatively high.
3. Looking at the school's teachers, for students, well-trained teachers are the guarantee of education quality.
4. Look at the training environment of the school, choose the auto repair vocational school to study, and before entering the enterprise, the practical experience of auto repair owned by the student plays a vital role in the job search process.
5. Look at the employment service, whether it can provide good employment recommendation services after the study, and whether the student can achieve it"Study. The job search is done in one step"It is a point that cannot be ignored when choosing an auto repair school.

It generally takes about three years to study auto repair, and the short-term major is only a few months.
1: It depends on you to go to ** school, there is a car school, and you can learn the professional knowledge of theory.
2: There is a repair shop, learn the actual operation.
3: It depends on whether you want to learn to repair a car or a truck. Most of the cars are gasoline. Trucks are now mostly diesel.
4: School Study: Internship after graduation.
Time is when you graduate. Repair shop learning, some one year, some three years depends on their own level of effort. But repair is a technical job that learns from all over the world.
Just like the car I am driving now, I asked more than 10 repairmen to see a problem, but the master didn't solve it, including myself who is also a repairman.
5: Learn to repair and divide into types: mechanic professional repair chassis or engine repair.
Specializing in electrical circuits, specializing in air conditioning. Welding, car beauty painting. There are different hours of study for different majors.
After hard work, no matter what major you study, a stupid person should not be more than 3 years.
The circuit maintenance of the car is not very easy to learn, and this also depends on the level of the individual and the master. Automotive circuits are one of the more complex skills in car maintenance.
There are a lot of electronic systems and sensors on the car, so the circuit of the car is very complex, and the maintenance of the car circuit is not easy to learn. There are many auto mechanics who can't read car circuit diagrams, and there are very few auto mechanics who can really understand circuit diagrams.
If you master the skill of repairing the electrical circuit of the car, you can quickly identify the cause of the fault if the car encounters a fault.
If you want to learn auto circuit maintenance, it is recommended to go to a very large and very professional auto repair institution and find a master who has been repairing cars for decades. In the process of studying, you also need to read some professional books.
Few of today's auto mechanics know how to repair cars, and most auto mechanics only disassemble and assemble parts. Nowadays, the automobile manufacturing process is very good, and the car generally does not have any serious failures. Even if there is a breakdown, the car will be able to run normally after the mechanic replaces the parts.
Nowadays, there are more and more automotive electronic systems, and the mechanical system is not easy to fail, and it is the electronic system that is prone to failure.
Before the actual operation, you need to be proficient in all the theoretical knowledge, and then cooperate with the operation, so that you can learn better.

Auto repair technology is not difficult to learn, but it is important to choose the right place. If you are an apprentice, you have to take 3 to 5 years to become a middle worker, if you want to become a big worker, you must not only have a good master, but also the learning time is relatively long. There are so many models that I have come into contact with that it is difficult to master. >>>More
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.
Automobile circuits are difficult to repair in repair, and it is difficult to learn and master them with a certain foundation and knowledge. Generally simple is car beauty and car decoration.
Automobile circuit short circuit is divided into soft short circuit and hard short circuit two phenomena, if the soft short circuit fuse is delayed to burn out, at this time the line will heat up, hard short circuit will be powered on the fuse immediately burned out. >>>More
How to learn car maintenance. First of all, self-study is definitely not recommended.
