How many volts does a car generator normally generate?

The usual voltage range for automobile generators is between 13.5 and 14.5 V. If the voltage is too high or too low, it will cause a breakdown. The car battery voltage is generally above 12.5, and the engine fuel system does not affect electricity generation. Automotive generators can be divided into two types: DC and AC generators. When using an alternator, you should pay attention to the following points: 1. The scale and dust on the surface of the alternator should be cleaned regularly, and good cleaning and ventilation should be maintained. 2. Regularly check whether all the fasteners related to the generator are loose, and tighten the screws of each part in time. 3. Make sure the drive belt has proper tension. Too little voltage will cause insufficient power output, and too much voltage will damage the neckgenerator wheel and bearings. 4. When installing the battery, be careful not to install it incorrectly. Usually you need to connect the positive wire first and then the ground wire, otherwise the diode will be burned out. 5. If an integrated circuit regulator is used, the ignition switch should be turned off immediately when the engine fails to start. 6. Never use the “scraping” method to test if the generator is working properly. 7. If it is found that the generator cannot produce electricity normally, the problem should be eliminated in time, otherwise it will cause more serious faults.
