Charging Test Result:
1) Charging Volt: Normal - Charging system shows the generator output normal, no problem
detected.
2) Charging Volt: Low - Charging volt of the charging system is low. Check drive belt of
the generator whether slip or running off. Check the connection between generator and
battery is normal or not. If both of the drive belt and the connection are in good condition,
follow the manufacturer's suggestion to eliminate generator fault.
3) Charging Volt: High - Generator output volt is high. Since most of the vehicle generators
are using internal regulator, the generator assembly has to be replaced
(Some old style cars are using external regulator, then directly replace the regulator.)
The normal high volt of the voltage regulator is maximum 14.7±0.5V. If charging volt is too
high, it will overcharge the battery. Therefore the battery life will be shortened and troubles
will be caused.4) No Volt Output:- No generator output detected. Check generator
connection cable and the belt condition.
5) Diode Test: - Through the test of charging current ripple, tester will find out whether the
diode is normal or not. When ripple volt is too high, it proves at least one diode is damaged.
Check and replace the diode.
Till now, all tests have been done.
