What is the normal current for car power generation?

[LaPaislee]

For car power generation current, domestic cars below 40mA and high-end cars below 80mA are considered normal. The detection of car power generation current is as follows: 1. Turn off all electrical equipment, including doors and anti-theft devices, disconnect the positive cable of the battery, and gently touch the terminal. If there is no spark or it is very faint and barely visible, it means the car itself is not discharging. If the spark is obvious, you need to find a certain electrical device that is self-discharging. 2. 1. First, check whether the battery terminals have poor contact. If there are oxides, pour boiling water over them, and the oxides will disappear. 2. Go to the battery dealer or repair shop to check whether the battery's power storage condition is normal. If the battery is aged or damaged, it can be detected. 3. Check whether there is a grounding or leakage in the wiring. If there is a discharge, a system check can solve the problem. 4. Check whether the generator is working properly, i.e., when the vehicle is running, disconnect the positive terminal of the battery. If the vehicle stalls, it proves that the generator is not generating power, and vice versa.
