How to tell if the car high voltage package is broken,

What are the symptoms of a broken ignition coil.

3. When accelerating, sometimes the power is cut off, resulting in acceleration weakness and shaking.

4. When the cylinder is lacking at the same time, the gasoline and air mixture in the cylinder cannot be ignited and will be discharged from the exhaust pipe. But in fact, the temperature of the exhaust pipe is very high, when the mixed gas reaches the exhaust pipe, it will burn due to the high temperature of the exhaust pipe, and at this time, a large amount of heat generated by combustion will block the three-way catalytic gas hole in the exhaust pipe, resulting in the failure of the three-way catalysis.

Whether it is the high-voltage package of the black-and-white machine or the high-voltage package of the color TV, if the boot screen is not light, you can put your arm close to the screen, and then turn it on, if the hair on the arm feels as if the wind is blowing, the high-voltage package is basically normal. If you don't feel this way, it means that there is no high pressure, but it is not necessarily that the high pressure package is broken.

If the high-voltage package is not on the machine, you can connect the two ends of the high-voltage output end with the neon bubble of the ordinary electric pen (to ensure that it is good), and then the two wires of the primary coil are continuously touched to a newer dry battery, if you can see the neon bubble flashing, it is basically normal, if there is no light or very dark talk, there may be a local short circuit.

Whether it is the high-voltage package of the black-and-white machine or the high-voltage package of the color TV, first remove the high-voltage cap from the picture tube and suspend it (note that it can only be carried out after discharging to the ground), and then turn on the power, if you see a spark and a special smell at the high-voltage cap, or even hear a boo, it is basically normal.

The high voltage pack of the same type was used to compare the forward and reverse resistance.

The high-voltage package of the display is basically the same working principle as the TV, and its main role is to generate anode high voltage, and provide various voltages such as focusing, acceleration, and gate. Due to the high voltage package working in the state of high temperature, high frequency, high voltage and high current, coupled with the influence of factors such as humidity or dust in the external environment, the probability of damage to the high voltage package is high.

The high-voltage package is commonly known as the line output transformer, and the output of high-voltage direct current is the role of the high-voltage package. This is exactly the same as the high-voltage pack in a TV. When used in televisions, it is used to accelerate the electronic screen to achieve sufficient brightness, and when it is used in computer LCD screens, it can supply power to the lamp tube to make the screen reach sufficient brightness.

The load on the ignition coil is too heavy, and if the power generation is too high, then the body electrical appliances, such as light bulbs, etc., will often be damaged. Of course, the quality of the accessories is not ruled out. It is best to measure the power generation first, if it is not higher than 14V, then the power generation is normal.

Cause of damage: 1. Breakdown of high-voltage filter capacitor in the package.

2. The high-voltage coil in the package is short-circuited between turns.

3. Leakage or breakdown of the high-voltage silicon stack in the package.

4. The primary coil in the package is short-circuited.

5. The focusing component in the package is aging, so that the focusing and acceleration voltage are unstable.

6. The insulation performance of the package body decreases, so that the high-voltage package is ignited internally or externally.

Notes: 1) "Vehicle" refers to motor vehicles and non-motor vehicles.

2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power unit and driven on the road for personnel or for transporting goods and carrying out special engineering operations.

3) "Non-motorized vehicles" refers to vehicles driven by human or animal power and driven on the road, as well as motorized wheelchairs for the disabled, electric bicycles and other vehicles that are driven by power units but have a design maximum speed, empty mass and external dimensions that meet the relevant national standards.

The high-voltage package of the car, that is, the ignition coil, is broken, mainly due to the following reasons: first. The load on the high-voltage package is too large, for example. The gap between the ignition spark plugs is too large, and a high voltage pack is required to provide a high flashover voltage.

This requires a high-pressure pot to pass through higher. current, which will cause the coil to burn out due to excessive current. The second aspect.

The high temperature in the engine compartment is damaged by the rapid aging of the high-pressure pack. Hope mine can help you.

Hello, about this kind of problem, the high-voltage package has a certain service life, because of long-term work, the ability of the internal components to withstand the voltage and current will be smaller and smaller, and finally it cannot be withstanded, and the internal electronic components are broken down and damaged. It is also possible that the spark plug causes the instantaneous current to be too large and break down the high-voltage packet. If you are not a professional maintenance personnel, it is recommended to go to the local dealer or repair station to check the specific problem, I hope to help you, hope!

If your high-voltage package is broken, there are many reasons, there is no overload to transport something, that is, more than the weight of the car if you run, the motor will be overloaded, there is no problem with the motor, there is no phase short-circuit, the controller part is not phase-missing, this has to be considered, the new energy high-voltage package is generally not easy to burn, unless it is a quality problem, if you drive normally, do not exceed the load capacity of the car, things are difficult to burn, the possibility of quality problems is very large, hey It is easy to break the tram that has been bought for many years, because the electronic components will age after a long time, and the control unit should also be considered, which should be checked by the computer on site to know the problem, you can go to the four S store to see what causes the engineer.

The phenomenon that the high-voltage package of the car is broken:

1. The high-pressure package is generally responsible for the ignition of one cylinder, and there are also responsible for two, if the ignition coil is broken, then the corresponding cylinder can not work, and the most obvious symptom is the acceleration weakness, accompanied by shaking.

2. If the high-voltage pack on the car provides less ignition energy (leakage), then the engine may also shake when idling.

3. Of course, the engine has a monitoring system, if the high-pressure package is broken, at this time you can see the engine fault light on the dashboard is on, in fact, it is to remind the individual of the failure.

4. Furthermore, if the high-pressure bag of the car is broken, and the corresponding cylinder is also on strike, then the mixture in the cylinder cannot be burned, and finally it can only be sent away by the exhaust pipe, but the mixture is not the object of three-way catalytic purification after all, so it will eventually adhere to the three-way catalytic and cause blockage.

5. It doesn't matter if an ignition coil strikes, if the other buddies also take a break, then the power of the car will be wasted, and the end result will be that the car will go abruptly until it turns off.

Generally, a high-pressure package is responsible for a cylinder (individual models will share a high-pressure package with two cylinders), if only one high-pressure package fails, and the rest work normally, then reluctantly emergency driving is not a problem, but the engine, frame and connecting parts of the car are very unfavorable, it is best to rush to the repair shop for maintenance.

If more than 1 cylinder does not work, then the car is likely to stop directly, and the individual can only call a trailer.

Precautions for the use of automobile ignition coils.

If the ignition coil is used improperly, it will cause damage to the ignition coil, so the following points should be noted:

1. Prevent the ignition coil from being heated or damp.

2. Do not turn on the ignition switch when the engine is not running.

3. Frequently check, clean and tighten the line joints to avoid short circuits or tie-offs.

4. Control the performance of the engine to prevent the voltage from being too high.

5. The spark plug shall not be "hoisted" for a long time.

6. The moisture on the ignition coil can only be dried with a cloth, and must not be baked with fire, otherwise the ignition coil will be damaged.

The above content reference: Encyclopedia - Automobile ignition coil.

Hello! Possible reasons for damage to the car's high-voltage pack: 1

The ignition is abnormal, and the engine is in poor condition. 2.The ignition coil burns out, and there is no high-pressure fire.

3.Abnormal wiring, resulting in short circuits and open circuits in other parts or electrical facilities. Burned or burned wiring and related electrical appliances.

5.Engine shake or body shake may occur while driving. 6.

Leakage sparks may cause fires. 7.Failure in other areas cannot be ruled out.

The phenomenon of the car high-voltage package breaking is as follows.

1. The high-pressure package is generally responsible for the ignition of one cylinder, and there are also two cylinders. If the ignition coil is broken, the corresponding cylinder will not work properly, and the most obvious symptom is weak acceleration, which can be accompanied by shaking.

2. If the ignition energy provided by the high-voltage package of the car is less (that is, leakage), the engine may also shake when idling.

3. Of course, the engine has a monitoring system, such as the high-pressure package is broken, and then you can see the engine fault light on the dashboard, which is actually to remind the owner that the fault has occurred.

4. In addition, if the high-pressure bag of the car is broken, the corresponding cylinder will strike, and the mixture in the cylinder will not be burned, and can only be sent away by the exhaust pipe in the end, but the mixture is not the object of three-way catalytic purification after all, so it will eventually adhere to the three-way catalysis, causing blockage.

Precautions for the use of high-voltage packs:

When using the car, it is necessary to prevent the car from getting wet, especially the position of the ignition coil. When wet, the ignition coil will be short-circuited and damaged. It is best not to turn on the ignition when the car engine is not running.

Always check the joints of the car wiring and keep them clean. In addition, if there are water stains on the ignition coil, do not dry it with fire, only use a rag to dry it. Drying over fire can also cause damage to the ignition coil.

If the high-voltage package of the car is damaged, there will be no sparks in the individual cylinders, resulting in idle shaking, and the ignition coil will not ignite, so once this happens, it is necessary to send it for repair as soon as possible.

The simple explanation of the ignition coil is that the spark plug is able to "create a spark" that ignites the part of the cylinder that mixes the gas. In fact, it is a transformer responsible for converting the vehicle's low-voltage current into high-voltage electricity, and each cylinder is normally equipped with a set of ignition coils and spark plugs.

In normal times, it is necessary to prevent the ignition coil from being heated or damp; Do not turn on the ignition switch when the engine is not running; Frequently inspect, clean, and tighten line joints to avoid short circuits or lapses. As for the replacement time of the high-voltage bag of the car, it is important to know that when the engine is running, there are often tens of thousands of volts of high-voltage pulse current on the high-voltage bag.

Because it works in a high-temperature, dusty, and vibrating environment for a long time, it will inevitably produce aging and even breakage. But in fact, there is no fixed replacement cycle for the high-voltage pack, as long as it works normally, it does not need to be replaced, and its service life is generally 100,000 kilometers or even longer.

If you suddenly feel that the car shakes when driving, and there is a very obvious lack of power, it is very likely that there is a problem with the high-voltage pack, and if the problem is serious, it will cause the car to stall.

Generally speaking, a high-pressure package is responsible for a cylinder (individual models will share a high-pressure package with two cylinders), if only one high-pressure package fails, and the rest work normally, then it is not a problem to barely drive in an emergency, but it is very unfavorable to the engine, frame and connecting parts of the car, and it is best to rush to the repair shop for maintenance.

If more than 1 cylinder does not work, then the car is likely to stop directly, and then it can only be called a trailer.

Hello, happy to answer your questions.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! For you to find out the following information, the engine will catch fire after the high-pressure package is damaged. This is a high-pressure package that can be exchanged for two cylinders.

It can be determined whether there is a misfire due to the high-pressure pack. The ignition spark can also be observed through the spark plug, and if the spark is weak or absent when the two are compared to ignition, the high-pressure package is damaged. Swapping for a high-pressure package is the easiest and fastest way to do it.

Interchange testing is recommended.

The high-voltage package is the ignition coil, the first thing is to check it in the car, the high-voltage package has a problem that will lead to a lack of fire, first confirm which cylinder is lacking fire, the simplest is to exchange the ignition coil with the normal working cylinder, if the original cylinder is short of fire after the exchange, it proves that the ignition coil is good. If there is a lack of fire in the cylinder that originally worked normally after the exchange, it proves that there is a problem with the ignition coil. The lack of electricity is the cause of the lack of fire, it may be a problem with the spark plug, it may be a problem with the ignition coil, it may be a problem with the high-voltage wire.

If the ignition coil problem is solved, the resistance can be measured with a million meters, and the internal resistance can be measured to know whether the inside of the coil is open.
