Common faults of automobile generators:

1, No charging, No charging Except that the drive belt is too loose and slippery, it is generally necessary to check that the generator itself does not generate electricity or the regulator fails, and the charging circuit is short-circuited.

2. The charging current is too small, which is generally caused by insufficient voltage of the generator itself, poor technical condition of the regulator and increased resistance of the charging circuit.

3, the charging current is too large, and the pointer of the automobile ammeter deflects to the position of the maximum charging current; If you drive at night, the engine speed is high, and the lights and instrument indicators will be particularly bright.

4. The charging current is unstable. When the engine is running at a speed above idle speed, the ammeter pointer swings left and right, indicating intermittent charging (sometimes charging, sometimes not charging), which generally indicates that the terminal voltage of the generator is unstable.
