Key Test Result
The screen automatically shifts to the Charging System Test after fihishing the Engine Start
Performance Test. In this screen, the current charging voltage is displayed together with
the test result.
If the charging voltage is low, less than 13V, turn on the electric devices such as air
conditioner or headlight observing the screen message. Try the Charging System Test again
under this loading condition, and check if the charging voltage increases or not.
※
26V or less for 24V System Test.
Charging voltage test result is fixed by pressing ENTER Key, and the instrument goes to
the ripple voltage test. Then the Charging System Test result is displayed on the screen.
In case of the bad test result with low charging voltage, check the alternator, or the engine
belt error.
Ripple Voltage is the small change of charging voltage which occurs when rectifying the
generated voltage by diode. If diode is damaged, the ripple voltage fluctuated sharply and
adversely affects battery and in-vehicle apparatus.
