How much does it cost to repair a car circuit fault?

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.

The short circuit of the automobile circuit is generally eliminated by using a short circuit detector, and if there is no equipment, it has to be eliminated manually.

The most important point of manually troubleshooting short circuit faults is to understand the direction of the car's wiring, first remove the wiring at the electrical end, and then check the wiring harness in sections according to the direction of the power supply.

When finding, a test lamp can be connected in series between the power supply and the short-circuit wire, and then the wiring harness can be pulled in sections to observe the change of the test lamp.

If it is simply a virtual circuit or poor contact, it should not exceed 50 pieces. If an electrical device is broken, it's hard to say.

There are also many faults in automobile circuit maintenance fault maintenance, and the specific reasons are different, and the maintenance is also different.

If the circuit of the whole car is replaced, it will be about 20,000 yuan, and the specific ** needs to be consulted in the repair shop.

This needs to look at the model itself, normal, if you say more than 100,000 cars, then you need to replace the whole car line, then the normal maintenance cost is more than 4000 or so, the wiring harness itself may be more than 1000 yuan, the main thing is that the working hours are expensive to change the whole car line, then the dashboard seat these door panels all need to be removed, so the main thing is that the working hours are expensive, and the approximate maintenance cost may be about 4000 yuan.

If you say it's the engine, it's a few hundred dollars, and if you change all the lines of the whole car, it will cost three or four thousand yuan.

If it's the engine, it's only a few hundred dollars, about six or seven hundred yuan.

This is the wiring harness, which does not contain artificial ones. If you add labor, it may be about 1200 yuan.

It costs six or seven hundred yuan to buy the line itself, and it must be manual, and three or four hundred yuan must be asked for labor.

Question: Okay, thank you.

Automotive electrification is considered to be a revolution in the development of automotive technology. The degree of vehicle electrification is regarded as an important indicator of the level of modern automobiles, and it is the most important technical measure for developing new models and improving vehicle performance.

Automakers believe that increasing the number of automotive electronic devices and promoting the electrification of automobiles is an important and effective means to seize the future automotive market.

Application changes. First, the mechanical structure of the car will also undergo major changes, and the various control systems of the car will develop to electronic and electrified to achieve "line control". Replace the original mechanical transmission mechanism with wires, such as "wire brake", "wire steering", "electronic throttle", etc.

Second, the 12-volt power supply system of the car is converted to 42-volt. With the increasing number of electronic devices in automobiles, the amount of electrical energy consumed is increasing dramatically. The existing 12-volt power supply can no longer meet the needs of all the electrical systems in the car.

In the future, the 42-volt power supply system of the integrated starter generator will be adopted, and the maximum output power of the generator will be increased from 1 kilowatt in 2005 to about 8 kilowatts, and the power generation efficiency will reach more than 80%. The implementation of the new standard for 42-volt automotive electrical systems will make major changes in the design and structure of automotive electrical parts, and mechanical relays and fuse protection circuits will be eliminated.

Do you want to change the wiring harness of the whole vehicle - the concrete implementer of the circuit connection? If it is no longer in production, you will not be able to find spare parts for wire harness accessories. Even if you can find the original wiring harness, or customize, it is quite expensive to replace.

There are many reasons for the battery to run out, 1. The battery has reached its service life, and the service life of the general battery is about 2-3 years, and some can reach four years. If the battery has reached the end of its service life, it needs to be replaced, different models of batteries use different models, if the old is replaced between 200-350 yuan. 2. The battery discharges the battery power due to excessive electricity, which needs to be floated and charged, and the cost is about 20 yuan at most.

3. Due to the damage of the generator, the battery is not charged in time and the electricity is discharged, which requires overhauling or replacing the generator, and charging the battery at the same time, so the cost is difficult to say. If you need rescue on the way, then add the cost of getting out of the car.

Call the maintenance staff to come, and my friend called 200-300 once. In fact, after coming, just wire his battery to your battery, and then let you take the car.

If the battery is fed for a long time, it is recommended to replace the battery as soon as possible, the battery I generally buy in the auto parts city, around 400-500, each car is not the same model.

If it is replaced, it will not exceed 500 yuan, which is charged by unit.

The best thing is to replace it with a new one, and few people repair it.

If there is a circuit problem in the car, the specific maintenance cost depends on where the line fault occurs and whether the circuit board needs to be replaced. Different repair shops have different working hours, ranging from a few hundred yuan to several thousand yuan.

If the vehicle has abnormal noise and heat.

Or frequent sparks, usually a sign of a line failure, if smoke or scorching smell must be a line fault, should immediately go to the 4S point for maintenance, to avoid causing more serious problems. Common line problems are:

1. The line contact is loose or poor, and it cannot be ignited;

2. Open circuit, short circuit, all kinds of instruments light up red and the dashboard does not move, indicating that the line is hot and hard due to long-term work, resulting in line open circuit fault;

3. Aging of components, resulting in short circuit;

The above situation is a line problem that occurs during normal use, generally speaking, there is a problem in a certain location, and it can be repaired for a few hundred dollars. If the circuit is changed without permission and the motherboard is burned out, this situation is more serious, and the whole car may be replaced, and the cost is about 5,000 yuan.

Expansion: Common line faults in automotive circuits are: loose wiring, poor contact, open circuit, short circuit, etc.

The thickness of the wire is designed according to the wattage and current size of the electrical appliance, if the wattage bulb is blindly replaced and the wire is still the original wiring harness, the wire will heat up, harden, and increase the current after a long time of work, which is easy to cause short circuit and power failure accidents. The power circuit of the car is made up of accumulators.

The main task of the generator, voltage regulator and working condition display equipment is to supply power to all electrical equipment in the whole vehicle and maintain the stability of the power supply voltage. When the engine is not working, it is powered by the battery, and after the engine starts, it is powered by the generator; While the generator supplies power to the electrical equipment, it also charges the battery.

In fact, the maintenance cost of the automotive circuit is relatively low, but the main reason is that the stage of finding the problem is more troublesome. Therefore, the proportion of working hours is relatively large.

It's hard to say, the circuit is a more complex whole.

You can only change the battery, obviously the battery can't hold electricity.
