NOTE
: If no increase rev detected, it shall be the fault of generator regulator or connection
with battery failed. Testerwill try 3 times to further detect, if still failed, it will skip the increase
rev detect and the test result displays "
No Volt Output
". See below:
Check the connection between generator and battery, then retest.
Charging Test Result
1.
Charging Volt: Normal
Charging system shows the generator
output is normal, and no problem is
detected.
2.
Charging Volt: Low
Charging volt of the charging system is
low.
Check drive belt of the generator
whether it is slipping 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 volt output is detected.
Check the generator connection cable
and the belt whether they are normal.
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.
