Causes and solutions for car failure to start:
1. The report may be incorrect. When starting a car with an automatic transmission, the gear must be placed in P or N. If it is placed in R or D, it will not start. There are also manual transmission cars that will not start unless the clutch is depressed.
2. The battery is discharged. This may be due to loss of power or expiry of battery life for reasons such as leaving the headlights off for a long period of time. It is generally recommended to replace the battery every two years. Additionally, the installation of argon headlights, high-power audio, DVDs, etc. are also the cause of vehicle circuit failures. It's easy to check if the vehicle is off, just press the horn to find out.
3. Spark plug. Generally, the most popular things common thing to do is to check the car's spark plug first, because this spark plug is a key part of the car's ignition system, and the vehicle's ignition system is the key to know if the heart engine of the car is working, therefore if the spark plug can work normally and affects the performance and efficiency of the vehicle. Emergency method: you can unscrew the spark plug and wipe it clean. You can start the car after reinstalling it. A thorough approach is to check the ignition system and eliminate the causes of low ignition energy, such as spark plug electrode gap, ignition coil energy, l status of the high voltage line, etc.
What does the car generator mechanical error code mean?
(1) Oil supply system causes: the low pressure oil line is blocked, the pipeline is loose and leaking, itthere is air in the high pressure oil pipe and the injection The technical condition of the oil device is not good and the injection timing angle is incorrect.
(2) Causes of the starting device: power failure, poor contact of the electromagnetic switch, poor contact between the starter commutator and the brush, and slippage of the clutch of the starter transmission mechanism .
(3) Insufficient cylinder compression pressure: the cylinder seal is damaged and leaking, the valve is not closed tightly, and the piston cylinder liner is worn and leaking.
(4) Insufficient air intake: The air filter element is clogged.
What are the symptoms of a broken car alternator?
It refers to the car's fault display code.
Continuing to drive will cause the vehicle's engine to stall due to insufficient power. The generator plays a relatively important rolein the vehicle, because it constitutes the main source of energy for the vehicle. It can power all vehicle equipment and can also charge the battery, which is very important. When a motor vehicle's alternator fault light comes on, the vehicle cannot continue to drive.
The vehicle should be driven to a nearby service center or repair shop at a safe speed. If the distance to the after-sales and repair workshop is too great, a trailer will be necessary to transport the vehicle. If the alternator fault light comes on, this indicates that there is a problem with the engine. If the vehicle is forced to roll at this time, it may result in greater vehicle breakdown.
For example:
When the check engine light comes on, it means there is a problem with the engine exhaust system. If it goes out a few seconds after starting the engine,this means a normal system self-test. If it stays on, there may be a problem with the exhaust system. If it lights up flashing, it means the engine is misfiring and damaging the catalytic converter.
The fault light is on indicating the current engineIf the system fails, it should be checked and maintained in time; in this case, a preliminary judgment should be made: turn off the anode or cathode of the car battery, disconnect it for a few seconds, and then reconnect it after starting; the car, see Is the instrument still working properly?
If the car alternator is broken, various symptoms may occur, such as car headlights or dashboard dimming, warning light coming on of energy production of the car and the emission of a signal by the alternator belt. peculiar smell. In order to eliminate the damage defectgenerator, the following methods can be used: 1. Keep the generator running and check the battery voltage with a voltmeter. Must be 13V or higher. If the voltage fluctuates between 13 and 14 volts at different speed changes, the generator is in good condition. On the other hand, if the voltage remains the same or drops, then the generator is indeed defective. 2. After starting the engine, turn it off after a few minutes. Touch the generator. If the generator is hot, the bearings may be worn or the copper insulating windings may be damaged, meaning the generator will soon lose its function. 3. Turn on the radio and start the engine. If your radio grinds or the sound quality is muffled every time you step on the accelerator, there is probably a problem with the alternator. 4. When the car does not start, use a meter to measure the battery voltage and record it. Startthen ground the car, then use the meter to measure the battery voltage and record it. If the car's alternator is not broken, the battery voltage will be higher when the car starts, around 13.7 volts, depending on the car, but it will definitely be higher than the voltage when the car does not start. not. If the generator fails and the car runs for 2-3 days, the battery will run out of power and the car will not be able to start on electricity. 5. Turn on the car headlights and check the brightness of the lights, then start the car and check if the lights dim. There is no big difference between the lights before and after starting, which means that the lights before and after starting the generator are reflected. In short, timely troubleshooting of generator faults can ensure normal driving and use of the car, thereby making it safer.
