    If the car suddenly loses power, it may be that the car has been parked for a long time, causing the battery to lose power, causing the car to fail to start. In addition, a power outage in a car can also be caused by incorrect wiring of the internal wiring, or a poor connection can also cause a power outage.

    First of all, test the vehicle's battery to see if there is electricity in the battery, and if the battery is normal, you need to check the car's ignition system and starting system. If there is a shortage of power in the battery, it is necessary to replenish the battery in time. In general, the battery can last for 3 to 5 years.

    In the process of using the car, we should always pay attention to the battery level. After parking, the engine should be turned off in time to avoid sudden power failure of the battery.

    In addition, it may also be that there is a problem with the fuse box itself or the connection part between the wiring harness plug and the fuse box, you can check whether the contact between the pin on the fuse box socket and the internal circuit of the fuse box is not firm, and the snap wire harness plug on the circlip is loose.

    Car batteries are an important part of a car. It provides power to the car's starting and in-car electronics. If the car battery suddenly dies, the car will not start.

    Car batteries have self-discharging characteristics, even if there are no electrical equipment, there is no load, it will self-discharge every day.

    For ordinary lead-acid batteries, the car battery suddenly runs out, which may be caused by insufficient battery electrolyte, because the battery will volatilize naturally during use, and if the electrolyte is insufficient, it will lead to a lack of power storage in the battery.

    In addition, the service life of the car battery is generally 4 years, if the car battery suddenly runs out, it may be that the battery life is up, and the only solution in this case is to replace the battery. If the car needs to be stopped for a long time, it is best to disconnect the negative pole of the battery, which can prevent battery loss and prolong the battery life. When the car is difficult to start, the battery fault warning light is on or the headlight is not idling, the battery should be checked to see if the voltage is normal, and the power should be charged in time if the power is insufficient, and if there is a fault, it should be repaired or replaced directly in time.

    It may be that the car battery has reached its service life, and the car battery also has a lifespan, and if it is not replaced for a long time, there may be no power. It is possible that the engine is damaged, and if the engine belt of the car is broken or the joints are loose, it is easy to break the circuit. It may also be that the battery electrolyte is insufficient.

    When the electrolyte is insufficient, the battery will be charged insufficiently.

    The main function of the car battery is to start the car. The capacity of the battery itself is not large. The reason may be that the car is not driven for a long time, the driving time of the car is too short, and the on-board electrical appliances are not turned off in time after the engine is turned off.

    There are generally the following reasons for the sudden failure of the car battery: the car has been parked for a long time and the battery has lost power, the battery has reached its service life, the engine is damaged, and the battery electrolyte is insufficient.

    1. The car is parked for a long time, resulting in battery power loss: the car is in a state of suspension, but due to the discharge characteristics of the battery itself, the battery will be discharged even if the battery is not used. The other is the alarm device, when the vehicle triggers the alarm system, the power consumption is even greater.

    There are also some high-end cars equipped with intelligent remote anti-theft system vehicles, due to the use of GPS positioning technology connected to the battery, it is also more likely to occur the situation of battery power depletion.

    2. The battery reaches its service life: at present, most private cars are using maintenance-free batteries, clean the electric eye on the battery, and observe that if the color inside is green, it means that the battery is normal; If it is black, it means that the battery voltage is low and the storage power is insufficient, which can be solved by charging; If it is white, it means that the battery has reached the end of its service life, and the only solution is to replace it with a new one.

    3. Caused by engine damage: due to the loose and broken belt of the automobile generator, the generator cannot be driven to work. Or because there is a rectifier in the car generator, the instantaneous high current will burn the diode of the rectifier.

    There are also carbon brushes and slip rings, which are too worn out and not in good contact. There are also stator coils, coil short circuits, open circuits, generators do not work. At the same time, if the power generation line is broken or the connector is loose, it will also cause the car battery to only discharge and not charge.

    4. Insufficient battery electrolyte: The electrolyte of the automobile battery will naturally volatilize and lose during use. The electrolyte should be between the highest and lowest levels. Insufficient electrolyte will naturally lead to insufficient storage of battery power in the car.

    5. The fuse is burned out, resulting in battery power loss: The car battery is out of power due to the car generator fuse being burned out and the car battery cannot be charged, and the fault judgment is that the generator fault indicator will be lit. The solution is to find the burned fuse and replace the fuse with the corresponding current size.

    6. Caused by the corrosion of the battery pile head: due to the corrosion of the automobile pile head, the car battery is out of power. After removing these white crystals, a conductive paste can be applied to the head of the battery pile, which can not only increase the conductivity, but also protect the head of the battery pile.

    Hello, if the car battery suddenly dies. Generally, it is a short circuit in the electrodes inside. Life is gone.

    The normal battery life is generally about three years. If you haven't forgotten to turn off the lights or something like that, you won't be able to turn on all of a sudden. Basically, the battery is broken.

    Use a multimeter to measure the amount of power generated, and replace the battery if it is normal.

    Question: How can I tell if the battery is good or bad after taking a ride for a long time or there is no power?

    Answer: Use a multimeter to measure the voltage of the battery after starting, if there is a voltage of about 14V after starting, it means that there is no problem with the power generation. Changing the battery will do the trick. There is also a way to use a battery tester to directly detect the life of the battery to know whether it is good or bad.

    1. Take the wire: This is a necessary item for the car to take the electricity, do not take two wires to make do, because the instantaneous current of the vehicle at the start can reach 200-600A, and the diesel car even reaches 1000A, if it is calculated, 10 square copper wires can ensure the smooth and safe start, so the car battery connection line must buy the right brand, the quality is the best, do not try to be cheap. This is one of the must-have items in the car, once the battery is out of power, you can take it out and use it, and you can also help others when you don't use it.

    2. Emergency power supply: This is a new type of power bank like a thing, there are two kinds of lead-acid and polymer lithium battery, which can help the vehicle with a loss of power to start, and can also have lighting, charging mobile phones and multi-functional supplies used with an inflatable pump to inflate the car. And it is generally portable, very lightweight, if you have it, you don't have to ask others for help.

    Be sure to charge it in time after use and keep it full of power to deal with emergencies.

    3. Positive, first connect the positive: first turn off all the electrical equipment on the car, make the key in the OFF position, open the cabin cover to find the battery, there are positive and negative poles written on the battery, generally the red "+" sign is the positive pole, and there are generally two wires, at this time, take out the red one, open the battery cover, pinch the clamp on the head to clamp firmly the positive pole of the battery of the electric car, and the clamp at the other end to clamp the positive pole of the battery of the rescue vehicle. Be sure to connect the positive electrode first, then the negative electrode, do not reverse the order, and do not use the battery clamp to touch anywhere except the battery pile head.

    4. Negative connection, negative connection: After the red positive electrode is connected, take out another wire, first clamp the negative pole of the tram battery, the negative electrode is generally black "—" number, and then pinch the other end of the clip, from beginning to end the clip do not touch other places, to clamp the negative pole of the rescue vehicle battery, when the connection will pop out of the electric spark, please don't be afraid, this also shows that you are right. The reason why the negative electrode is not connected first is because the whole vehicle is basically a negative electrode (that is, commonly known as "tie iron"), if the negative electrode is connected first, when connecting the positive electrode, the clip will cause a short circuit and burn the parts on the car when it touches any conductive place in the body.

    5. After starting the vehicle, first remove the negative, and then dismantle the positive: after the battery is connected, the rescue vehicle will first ignite and charge the battery, and then the no tram enters the vehicle to open the key, at this time the instrument light will be lit smoothly, and then try to ignite (not more than 5 seconds), if it fails to start smoothly, step on the accelerator of the rescue vehicle, and the speed is kept at about 2500 rpm, and then the tram is ignited again, if the starter is no problem, the car has oil in the case of general can be started smoothly, after the non-electric vehicle starts, Remove the negative clamp first, then remove the positive clamp, for the same reason as why the negative pole is followed by the fourth one.

    The positive and negative poles of the battery must not be reversed, and the order of assembly and disassembly should be strictly in accordance with the order of first connecting the positive and then the negative, and the first dismantling and then the positive.

    Hello, it may be that your generator is not generating electricity. Your dashboard should have a battery-shaped, red fault light. Because the generator does not generate electricity, the electrical equipment of the car is powered by the electricity stored in the battery. So it causes the car to lose power. Thank you, hope to adopt

    There may be several reasons for this:

    When the service life of the battery comes, it can no longer be charged, or the charging efficiency is low, and the battery does not store power may be due to the additional electrical equipment installed on the vehicle, which will still use electricity after the vehicle is turned off, resulting in a loss of power to the battery.

    It is possible that some electrical equipment has not been turned off after the car is turned off, such as small lights, indoor lights, etc., resulting in the battery of the vehicle being drained.

    Just a few days after buying a new car, the battery is unlikely to be broken. Therefore, the possibility of battery failure can be basically ruled out.

    Generally, the battery is out of power, and there is one reason for the new car: the battery is self-discharged.

    Forgetting to turn off your lights after parking at night is the most likely. The anti-theft lock will not cause the battery to be damaged in a short period of time, and the suspicion can be basically eliminated (unless the door is not closed tightly, and the anti-theft device keeps alarming).

    1. Trolley starting is the most commonly used and most effective emergency starting method, but this is a last resort and cannot be used often, because this has certain damage to the engine and clutch, and automatic transmission vehicles should especially avoid using this method to start.

    2. In order to avoid the battery being unable to be charged when it is out of power, the owner should prepare a jumper cable in the car, which can be bought in general auto parts stores. However, when connecting jumper cables, it is important not to misconnect the jumper cables in the order in which they are connected. It is necessary to first connect the positive terminal of the dead battery with the positive terminal of the rescue vehicle battery, and then connect the negative terminal of the rescue vehicle battery with the metal part in the engine compartment of the dead car (grounding wire).

    3. The most reliable way is to contact the rescue vehicle in time, and then connect the jumper cable, and temporarily charge the rescue vehicle to start the engine.

    There may be two reasons for the battery to be dead, one is that the life of the battery is expiring or there is a problem, and the other is that the headlights are forgotten to turn off and the other is a loss of power. It can be started by one of the following three methods: 1. It is towed and dragged by other vehicles; 2. Borrow the power supply of other vehicles to start; 3. Use downhill to start.

    The method of using the battery to connect the wire, borrowing the power supply of other vehicles to charge, the specific method is: prepare two relatively thick wires, if it is purchased in the market, it is generally divided into red and black. One end of the red wire can be connected to the positive pole of the tram battery, and the other end can be connected to the positive pole of the tram battery.

    One end of the black wire is connected to the negative pole of the battery of the tram, and the other end is connected to the metal part of the tram. A tram starts first to drive the tram to land. Here we also want to emphasize that the power supply car should be in a running state, first lapping the positive electrode, and then lapping the negative electrode; After starting, first loosen the negative electrode, and then loosen the positive electrode.

    This can prevent the negative pole from accidentally touching the positive pole with the car body halfway after connecting the negative electrode first, resulting in a short circuit. "
