The car won't start and the igniter keeps ringing. What happened?

It may be because the battery is dead, and the creaking sound is the sound made by the starter. If this happens, you can call your friend who is driving, so that you can start the engine. The battery is a very important part of the car. When it is not started, the battery supplies power to the electronic equipment of the whole vehicle. The battery is also responsible for starting the engine. After the engine is started, the generator supplies power to the electronic equipment of the whole vehicle, and the generator also charges the battery. If the battery doesn't work, the engine won't start. The battery is a wearing part and needs to be replaced regularly. Batteries in cars can generally last for 3 to 4 years, and some batteries with better performance can last longer. However, the batteries of some cars don't last that long, which is caused by the incorrect usage habits of the owners.

When the engine is not started, don't sit in the car for a long time and use electronic equipment, which will reduce the service life of the battery and be detrimental to the battery. When using the car in winter, try to avoid parking outside at night, because the outdoor temperature is very low in winter, which will also reduce the service life of the battery. When using the car at ordinary times, if you avoid some incorrect usage habits, you can prolong the service life of the battery. If the battery is not good, replace it in time, otherwise it will affect your car.

The car can turn on the headlights or interior lights before confirming the start, and observe whether the lights change during the start. If it is obviously darkened, the battery voltage is insufficient. The current consumed during startup is very large. When the battery power supply is insufficient, the starter can't drive the engine to reach the starting speed, and the repeated attraction of the magnetic bag and the starting relay produces a click sound.

The voltage of automobile battery is too low or invalid. If the automobile is used improperly in daily life, the service life of the battery is generally 3 to 5 years. If it exceeds this time limit, it must be replaced in time. The fuel system is short of fuel supply, and the air-fuel ratio of the mixture required by the engine cannot be reached. Check whether the fuel is sufficient. There are too many carbon deposits in the intake pipe, throttle and idle motor, which makes the engine mixture fail to reach the required air-fuel ratio. Check idling, the car environment is poor, which will accelerate the production of carbon. The starting motor or related circuit fault causes the electromagnetic coil to be unable to maintain the attractive state and provide the torque required for starting.

The ignition system failed to start the engine, the key door was always in the starting gear, and the starting relay repeatedly stuck. The temporary solution to the car's incombustion is to prepare two lines to power another car: first, turn off the engine of the dead car, and the lines must be connected in sequence, otherwise there is a danger of short circuit, one end is connected to the battery positive electrode, and the other end is connected to the battery positive electrode; Take the negative electrode of the other battery, and then connect the other end to the engine housing or body of the electric vehicle. It should be noted that during the wiring process, you must not touch other places. After wiring, start the electric car and then start the non-electric car. Finally, the sequence of removing stitches is just the opposite of that of connecting stitches. For the sake of safety, we must operate in sequence.
