Wait for the countdown from 10s to 0s. As soon as it reaches 0s, the results will automatically display as
example shown below (Fig.55).
9. If either minimum or maximum charging volts are not within the voltage range limits then it will display one
of the screens as below (Fig.56 & 57) and it will highlighted which prompt you to check the charging
system for the fault.
OR
Testing diode ripple at idling speed with electrical load ON
This test is to check the AC ripple of the alternator diodes whether it is within the 0.5V limit. Normally if
one of the diodes is faulty, the AC ripple will produce higher than the accepted 0.5V.
8. Continue from the previous test (either Fig. 55, 56 or 57); the Analyser will automatically proceed to
diode ripple test. The display will show as below (Fig.58).
