The editor said that many friends don't know much about cars. Small presentation from the editor who often asks me: How to judge the quality of the anti-return wheel of the generator. If you address this issue, you may be able to reduce the detours.
A multimeter can be used to measure the generator voltage. The normal power output value of the generator is between 12.5V and 14.8V. If the voltage is abnormal, the generator will be damaged.
To visually check the quality of the alternator, you can check based on appearance and clearance. Hold the generator and rotate it up and down to determine whether the axial direction and the front bearing clearance have become greater. , and whether the axial direction and clearance have changed. Indicates there is a problem with the generator.
Once the one-way wheel of the generator is broken, the car no longer has a buffer in csudden acceleration or deceleration and makes considerable noise when starting. After starting, gently press the accelerator and the engine will make a sound. The important function of the one-way wheel of the generator is to relieve the impact of the motor during sudden acceleration or deceleration and adjust the power output.
When a unidirectional wheel is damaged, it must be repaired immediately. Otherwise, the car battery cannot be charged. This way, the car will not catch fire, the battery will be low, the car headlights will become quite dim, and eventually the car's driving ability will disappear, affecting engine timing, etc.
Application scope of automobile generator one-way wheel:
Diesel engines, V-cylinder engines with cylinder deactivation function, 2-mass flywheels, transmissions automatic change shockhigh speed, alternator with high inertia torque.
