The most common problems and solutions for car starters?

The most common problems and solutions for car starters are as follows:

1. The starter drive gear does not rotate and cannot work normally.

When this situation occurs, the reasons for it are usually more, which may be caused by battery damage, insufficient kinetic energy, damage to the circuit from the battery to the starter part, or it may be caused by the ablation of the contact disc of the starter switch, excessive engine resistance, or direct damage to the starter.

When encountering this situation, we first need to make a preliminary diagnosis of the reason why it cannot be started before we can deal with it accordingly. If the line is damaged, the line can be repaired; If the battery is broken, the battery can be replaced; If the contact disc of the starter switch is ablated, the engine resistance is too large or the starter is directly burned, it needs to be dealt with at the corresponding maintenance point.

2. The power output of the starter is insufficient and cannot drive the crankshaft.

When this happens, it is manifested that the starter is moving, but the movement is relatively slow and cannot drive the crankshaft. Most of the reasons are that the short circuit of the excitation coil and the loss of power of the battery can cause the lack of power of the starter, and it can be dealt with accordingly.

3. After the starting switch is turned on, the starter rotates at high speed and the engine cannot start, the reason for this situation mostly appears on the transmission mechanism, and it may also be caused by the wear of the transmission gear or one-way clutch.

4. The sound of the starter running is harsh.

This condition is most likely caused by a stuck one-way clutch or improper installation of the starter. First, the crankshaft is rotated at an angle, and then the starting switch is turned on. If the impact sound disappears and the starting engine is meshed, it means that part of the meshing end of the flywheel gear ring is broken and should be replaced.

If the crankshaft cannot be turned to any angle to eliminate the impact sound, and the driving pinion can not be meshed all the time, it indicates that the starter fork stroke or electromagnetic switch stroke is too short, resulting in high-speed rotation of the driving pinion before it is meshed.

When the starter switch is turned on, the starter housing is obviously shaking, indicating that the starter fixing bolt or the clutch shell fixing screw is loose and should be tightened immediately, otherwise it may cause the starter drive end cover to be broken.

In addition, the cause can be roughly identified based on the characteristics of the impact sound. Generally, the impact sound caused by improper stroke adjustment or idling is continuous, while the impact sound caused by the loosening of the starter fixing bolt or clutch housing or damage to the flywheel tooth is intermittent and can sometimes be engaged in the start. Idling with an impact sound is diagnosed in the same way as a starter idling fault.

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, 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.

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.

The big throttle will not be the engine, and the vehicle is not so squeamish; But looking at your situation, if you slip the big throttle on the mud road, the most hurtful thing is the clutch, and the clutch will burn out if you slip the big throttle for a long time. Therefore, if there is any change in the gear shift when the hot and cold car is hot, the separation is not smooth, and the starter load will not be fast when the starter is started; Another look is whether the battery is a little fed, resulting in poor starting.

The 2 most common scenarios:

1. Circuit problems. Try ignition, listen to whether there is a ignition sound, no, it means that there is a problem with the ignition system circuit.

2. Oil circuit problems. If there is a ignition sound, but the car is not on track, check the oil circuit, most likely: 1. The oil pump is broken. 2. The oil pump is not broken, but the oil circuit is blocked.

All of the above is no problem, find a 4S store.

1. The battery loses power, or the connecting wire is broken or the joint is loose; 2. The contact of the starting relay is seriously ablated or its coil is broken; 3. The contact of the starter electromagnetic switch is seriously ablated or its suction coil is broken; 4. The internal winding of the starter DC motor is broken or short-circuited; 5. The armature shaft of the starter is bent, and the gap between the shaft and the bearing is too tight; 6. The commutator is seriously ablated, the brush is worn too much, the brush is stuck in the brush holder or the brush spring is too soft.

Cars have become a must-have tool for everyone to get around. Of course, automotive knowledge is essential. In order to facilitate everyone to understand this knowledge, today, Bian Xiao will tell you how to solve the problem of the car start system. Interested friends can learn about it, it may be helpful to you.

There are many reasons why a car can have problems with the starting system, one of which is a problem with the battery-powered system, such as low battery power, damage to the power supply insurance or relay, loose starter cables and battery terminals, or oxidation of the terminals. The second reason is the problem of the starting relay, such as the short circuit of the inductance of the starting relay, the open circuit or grounding of the inductance of the starting relay, the ablation of the moving contact or static contact of the starting relay, and the gap between the core of the starting relay and the contact arm is too large. The third reason is the problem of the starter, such as the problem of the starter DC motor, the transmission mechanism, the adjustment device, etc.

The fourth reason is the problem with the start switch, the starting gear of the car is out of order. (1) Check the battery: when the horn does not sound, the instrument light is dim, the power window moves slowly, the car headlights are dim, and the anti-start indicator light flashes (some models), check whether the battery terminals are oxidized or have poor contact and poor battery grounding.

The starting voltage of the starter should be greater than (2) Test the starter: use the starting terminal to short-circuit the main connecting rod of the cable connecting rod of the starter. If the starter does not work, it means that there is a problem with the electromagnetic switch of the starter and the starter needs to be removed for maintenance.

3) Test the ignition switch and the relevant circuits of the ignition switch. (4) Check the car starting relay and starting safety book, and judge the problem accordingly.

Common faults of automobile starters: 1. Improper adjustment of the travel of the starting switch or electromagnetic switch; 2. Improper adjustment of the gap between the armature movable fixed contact and the movable contact; 3. The starter drive pinion or flywheel tooth is worn out or even slipped; 4. The fixing bolt of the starter is loose or the clutch housing is loose; 5. Internal failure of the starter. The reasons for the failure of the starter idling are as follows:

1. The fork of the mechanical forced starter is de-grooved, and the driving pinion cannot be pushed, or its stroke is improperly adjusted, and it cannot enter the mesh; 2. The core stroke of the electromagnetic switch of the electromagnetic control starter is too short; 3. The auxiliary coil of the armature mobile starter is short-circuited or broken, and the armature cannot be brought to the working position; 4. The one-way meshing of the starter slips. The reasons for the failure of the starter are as follows: 1. The battery is insufficient or the connecting wire is loose and the contact is poor; 2. Ablation of the contact of the starting switch or short circuit of the electromagnetic switch coil.

Turn on the start switch, there will be a controlled knocking sound when the starter is running, and the engine cannot be driven; When the start switch is turned on, the starter only rotates empty, and the pinion cannot engage the flywheel gear ring to drive the engine to rotate; The starter rotates slowly and weakly, making it difficult for the engine to drive the birds; When the starter switch is turned on, the starter only clicks and does not start.

The reasons why the abnormal sound of the starter cannot drive the engine to run are: improper adjustment of the stroke of the starting switch or electromagnetic switch; Improper adjustment of the gap between the armature moving fixed contact and the moving contact; The starter is active, the pinion or flywheel tooth is worn or even slipped; Loose starter fixing bolts or chaotropic coupling housing; Internal failure of the starter.

The reasons for the idling failure of the starter are as follows: the mechanical forced starter shifts the fork out of the groove, cannot drive the pinion, or the stroke is improperly adjusted and cannot be meshed; The travel of the electromagnetic switch core of the electromagnetic starter is too short; The auxiliary coil of the movable armature starter is short-circuited or open-circuited, and the armature cannot be brought to the working position; Starter one-way clutch slippage. The reasons for the failure of the starter to turn are:

The battery is low or the connection cable is loose and the contact is poor; Ablation of the starter switch contact or short circuit of the solenoid switch coil.
