Can the car still run if the alternator is broken?

The generator can still work if it is broken, but this will cause insufficient power supply and the vehicle may stall at any time, damaging the battery and shortening its lifespan. Methods for inspecting generator damage: 1. Check the battery with a voltmeter while the generator is running. The voltage reading at this point should be around 13 volts or a little high. If the voltage oscillates with speed between 13 volts and 14 volts, the generator is in good condition; on the other hand, if the voltage is constant or decreases, the generator is indeed broken; 2. Start the engine then stop it after a few minutes. If contact with the generator causes the generator to heat up, the bearings may be worn or the copper insulating windings may be damaged. This indicates that the generator failed quickly. 3. Turn on the radio, turn on the engine, and it doesn't matter when you pressez on the throttle, if the radio is loose or the sound quality is fuzzy, there is probably a problem with the generator. 4. When the car does not start, use the meter to record the battery voltage, then start the car and use the meter to record the battery voltage. If the car's alternator is not broken and the car starts, the battery's V number will be slightly higher. About 13.7 V. Although this varies from car to car, it will definitely be higher than the V number at which the car will not start. The most obvious thing is that if the generator fails and the car is driven for 2-3 days, the battery will run out of power and the electric car will not be able to turn on or start. 5. Turn on the headlights and check the brightness of the lights before starting the car. The lights went out and the car started. I first look at the brightness of the headlights, thenI check the brightness with the accelerator pedal. There is no big difference between the lights before and after starting, indicating that the generator is not running. This is reflected in the lights before and after startup. If it gets brighter, the generator is good, but the battery is not.
