Check the generator one-way wheel: 1. Measure the generator voltage with a multimeter. The normal value is between 12.5V and 14.8V. If the voltage is abnormal, the generator is damaged; 2. Check the quality of the generator through the appearance and clearance, swing the generator from front to back, left to right, and judge whether the direction of the front bearing and the clearance become larger. If the axial direction and clearance change, it indicates that the generator is faulty. The one-way wheel of the generator is used to alleviate the impact of the engine when the vehicle accelerates or decelerates rapidly, and adjust the power generation. After the one-way wheel of the generator is damaged, the vehicle has no buffer during rapid acceleration or deceleration, which will produce abnormal noise when starting, and the engine will also produce abnormal noise when gently stepping on the accelerator. After the one-way wheel of the generator is damaged, it needs to be repaired in time, otherwise the vehicle battery will not be charged, and insufficient battery power will lead to weak driving and flameout of the vehicle.
