If the car's alternator is broken, there may be various symptoms, such as the car's headlights or dashboard dimming, the car's power production light coming on and the emission of a particular odor from the alternator belt, etc. In order to eliminate the generator damage fault, 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 insulated copper windings may be damaged, meaning the generator will soon lose its function. 3.AlTurn 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 likely a problem with the alternator. 4. When the car does not start, use a meter to measure the battery voltage and record it. Then start 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 noThere is a 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.
What causes a car alternator to break?
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, it 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.
When the malfunction indicator light turns on, it means that the current engine system is defective and requires timely inspection and maintenance. In this case, a preliminary judgment must be made: cut off the anode or cathode of the car. battery and unplug it for a few seconds, then hang it up again after starting the car, see if the instrument can still work normally.
When the engine (exhaust system) trouble light is on, if the water temperature gauge and oil pressure warning light have not yet tripped, the car can still drive. But be sure to drive slowly and carefully and find the nearest auto repair shop for maintenance. If the water temperature is too high or the oil pressure warning light is on and you clearly feel that the vehicle is having problems, you should immediately stop and seek help.
Sources that cause the engine fault light (exhaust system) to come on: poor fuel quality, carbon deposits on thespark plugs, oxygen sensor failure, engine knocking, water temperature sensor damage, engine cylinder shortage, etc. If not resolved in time, it may lead to engine damage and substandard exhaust emissions.

Many novice car owners are very strange. The battery is obviously limited, but somehow the car ones tend to last a long time. In fact, this is due to the constant charging of the car's alternator. When the engine is running, the generator will share some of the engine's energy to charge the battery. What are the symptoms if a generator breaks down? Can the generator be repaired if it breaks down?
What are the symptoms of a broken car alternator?
The generator is the most important component of the car's electrical systemture and can be considered the real source of energy for the car. Batteries simply convert energy. Once the generator fails, the most obvious feeling for our car owners is that the vehicle's electrical appliances, horns and headlights cannot work normally, especially the volume of the horn and the brightness of the lights are the most eye-catching.
In addition, once the generator is damaged, the electrical energy in the battery will be quickly consumed by the car and cannot be replenished. At that time, the battery will seriously lose power. If the power loss is too great, the battery will be damaged.
Since many parts of a car require electrical power to operate, the most basic is starting the engine. If the car lacks power, the machine will not respond to starting the engine. It is alsoent the most obvious and influential symptom. If you want to determine a fault, it is best to use a multimeter to test the charging circuit.
Can the generator be repaired if it breaks down?
In fact, the operating principle of the generator is relatively simple, but the installation process is a little more complicated. Basically any instrument that can be manufactured can be restored through maintenance, but this takes into account maintenance costs and post-maintenance usage.
You should know that repairing a generator now generally costs more than 200 yuan, but the total price of replacing a generator is only about 500. No one can guarantee that the repaired generator will be the same as before the failure. If the generator suddenly breaks down during high-speed driving, the cost will be even higher, so it is almost not possible to repair the generator.misser. To improve repair rates, all generators are directly replaced.
