What are the common fault phenomena and causes of automobile starting system?

There are many reasons why a car's starting system can fail, one of which is the battery-powered system: for example, the battery is insufficient, the car's main power supply is fused or the relay is damaged, and the starter cable and battery terminals are loose or oxidized. The second reason is a faulty starter relay

For example, the inductance coil of the starter relay is short-circuited, the inductance coil of the starter relay is open or grounded, the moving contact or static contact of the starter relay is ablated, and the gap between the core of the starter relay and the contact arm is too large. The third reason is starter failure: such as starter DC motor failure, transmission mechanism failure, control device failure, etc.

The fourth reason is a faulty starter switch and a faulty car starter gear.

1) Press the horn or turn on the headlights if the horn is hoarse.

Or it doesn't sound, or the light is dimmer than usual, it means that there is a problem with the power supply, you should first check whether the battery pole pile and the wire clamp, the starting circuit wire joint is loose, and whether the touch wire connection is heated.

2) If it is judged that there is no problem with the power supply, use a screw to short-circuit the two binding posts connected to the battery and the internal motor on the starter electromagnetic switch. If the starter does not rotate, it means that there is a fault inside the motor, and the starter should be disassembled and inspected; If the starter idling is normal, proceed to the next check. (3) Connect the electromagnetic switch binding post with the starter power supply binding post with a screw, if the starter does not rotate, it means that the starter electromagnetic switch is faulty, and the electromagnetic switch should be disassembled and checked; If the starter is functioning properly, the fault is in the starter relay or related wiring.

4) Use a screw to short the two binding posts connecting the battery and the starter on the starter relay. If the starter does not turn, the wire connecting these two binding posts should be checked; If the starter is functioning properly, take the next step to check. (5) Short the two binding posts connecting the battery and the ignition switch on the starting relay.

If the starter does not rotate, it means that the starter relay is defective, and the starter relay should be dismantled or replaced; If the starter can operate normally, the fault lies in the wire from the starter relay to the ignition switch or the ignition switch itself, and it should be overhauled.

I think this may be due to a change in the temperature, so it may be some common faults, or because there are some blockages, so there will be some impact.

Weak starting, possibly due to a dead or low battery. Difficulty in starting, probably due to insufficient speed of the starter.

The common faults of the automobile starting system mainly include: the starter does not work, the starter is weak, the starter is idling, the starter is starting to make teeth, and the starter cannot be released from starting.

Car Boot System Troubleshooting:

1. Check the battery: when the horn does not sound, the instrument light is dim, the power window is slow to lift, the headlights of the car are dim, and the anti-start indicator light is flashing (some models), check whether the battery binding post is oxidized or poorly connected, the battery is poorly grounded, and the starting voltage of the starter is measured to be greater than.

2. Check the starter: short the main terminal rod of the cable on the starter and the starting binding post, if the starter can not work, it is said that the electromagnetic switch of the starter is faulty, and the starter needs to be removed for maintenance.

3. Check the ignition switch and the ignition switch related circuits.

4. Check the car starting relay and starting insurance to judge the obstacle position.

1. There is no response when starting;

2. There is a noise and blind sound at starting;

3. The stool starter motor teeth are coarse and hollow and cannot fit the engine flywheel gear ring;

4. Weak starting.

1. Common faults of automobiles: common reasons why the engine cannot start: 1

The circuit is faulty or the battery is dead. 2.Ignition coil or spark plug failure.

3.The oil circuit is faulty, the oil pump is damaged, and the oil tank is free of oil. Workaround:

If the battery is out of power, you can use the wire or emergency power supply for ignition, and then it may be a circuit oil circuit failure, and it is recommended to send it to the repair shop. 2. Common faults of automobiles: tire puncture, puncture and other fault solutions

The puncture tire should be replaced in time, or the tire should be repaired. If it is a flat-proof tire, although you can continue to drive with a flat air, it is still recommended to repair the tire in time. When a tire bursts, remember not to slam on the brakes, slam the direction, hold the direction, brake slowly, and deal with it calmly.

After the car is stopped, change the spare tire or contact the rescue. 3. Common faults of automobiles: common causes of brake failure:

1.Maintenance is not in place 2Inadequate operation leads to thermal decay.

Solution: Maintain the brake system. Always check the consumption level of brake discs, brake pads, etc.

Try to avoid applying the brakes for a long time in daily driving, and go downhill in low gear. Avoid overheating the brake pads. Fourth, the common fault of the car:

Common causes of squeak and squeak:1Abnormal body noise.

2.The number of lifts is excited, and the machine is abnormal. Workaround:

If there is a slight abnormal noise of the body, it is usually caused by the lack of rigidity of the body, which will not affect the driving, but if there is a violent abnormal noise, it is recommended to stop for inspection. The engine screeches are usually caused by timing belts, fan belts, etc. It is recommended to inspect components such as generators, water pumps, power steering sock pumps, etc.

And send it for repair in time.

1. See if it is caused by hanging the wrong gear. Some people do not hang the gear in P gear when they stop and turn off the engine, but hang it directly in D gear. Because, if you hang the gear in D gear or R gear, there is no way to start the fire, and you can only start the fire if you hang the gear in P gear or N gear.

Therefore, when he wanted to start the fire again, he could not light it.

2. See if the car is out of gas. In addition to the battery running out of power, the fire cannot be ignited, and the car cannot be ignited when the gas is out. Usually this situation is because the engine is not turned off when you get out of the car, so that the fuel consumption is dried up and the electricity is used up, so the car has no way to ignite the fire.

3. Is there a fault in the gasoline pump? This reason is also somewhat similar to the running out of gasoline. If the starter can run normally when the ignition is ignited, but the car is not on, you need to check the gasoline line to see if there is a problem with the gasoline pump.

4. See if the starter is faulty. If the starter fails, this problem is very similar to the battery running out of power, and it will also cause the fire to not ignite.

5. Is there too much carbon deposited in the throttle place? If there is too much carbon deposited in the throttle, it will also not catch fire. In this case, just step on the accelerator a little bit to ignite the fire.

6. See if the crankshaft position sensor is faulty. There was damage here, and when the ignition was fired, the engine's computer had no way to receive the signal, and there was no way to control the spark plug for ignition. I hope it will be helpful to you, and I hope to adopt it.

1. Check the battery: when the horn does not sound, the instrument light is dim, the power window is slow to lift, the headlights of the car are dim, the anti-start indicator light is flashing (some models) and other conditions, check whether the battery binding post is oxidized or poorly connected, the battery is poorly grounded, and the starting voltage of the starter is measured to be greater than.

2. Check the starter: short the main terminal rod of the cable on the starter and the starter binding post, if the starter cannot work, it means that the electromagnetic switch of the starter is faulty, and the starter needs to be removed for maintenance.

3. Check the ignition switch and the ignition switch related circuits.

4. Check the car starting relay and starting insurance to judge the fault location.

The fault diagnosis and elimination of the automobile starting system must be carried out through professional learning, and it cannot be operated without professional learning.

Hello Common Phenomenon:

1.When the start switch is turned on, the starter rotates at high speed and the engine crankshaft does not respond. This phenomenon indicates that the fault occurred on the transmission mechanism of the starter, which may be caused by wear of the transmission gear or one-way clutch.

2.The starter does not work properly, and the drive gear does not turn. There are many reasons for this, such as problems with the power cord, ablation of the contact disc of the starter switch, and excessive engine resistance.

3.The starter has insufficient power output to drive the crankshaft. A short circuit in the excitation coil and a loss of power in the battery can cause a lack of power in the starter.

After the car road is started on this meter, it is displayed, if it is displayed on this meter, what is the problem? He's going to have it. If you really don't know what to do, you can just open a four-S store and check it.

The common faults of the car starting system are mainly as follows:

The starter does not work, the starter is running weakly, the starter is idling, the starter is starting to make teeth, and the starter cannot be released. The most common of these failures are the starter not working and the starter not functioning.

Solution: 1. Check the battery: when the horn does not sound, the instrument light is dim, the power window is slowly lifted, the headlights of the car are dim, and the anti-start indicator light is flashing (some models), check whether the battery binding post is oxidized or poorly connected, the battery is poorly grounded, and the starting voltage of the starter is measured to be greater than.

2. Check the starter: short the main terminal pole of the cable on the starter walkie-talkie and the starter binding post, if the starter cannot work, it means that the electromagnetic switch of the starter is faulty, and the starter needs to be removed for maintenance.

3. Check the ignition switch and the ignition switch related circuits.

4. Check the car starting relay and starting insurance to judge the fault location.

If this starter is stupid and normal means that the motor does not react, the first thing to check is the power supply system to see if the battery is powered? Secondly, check the 30 ends of the motor with the source and the 50 terminals to see if there is electricity?

Car starting system failure, first of all, you have to know whether the motor is not working or the motor is working but it cannot start. It is necessary to distinguish the mustard before repairing.
