8. 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 or Fig.57) and it will highlight which prompt 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 acceptable 0.5V.
9. Continue from the previous test (either Fig. 55, 56 or 57); the Analyzer will automatically proceed to diode
ripple test. The display will show as below (Fig.58):
10. While the engine is still running, make sure the air conditioning is OFF and the headlights (low and high beams)
are switched ON. Press key to continue and the display will change to (Fig.59) as shown below:
11. Wait for the countdown from 10 to 0. As soon as it reaches 0, the results will automatically display as example
shown below (Fig.60):
12. If the ripple voltage is above 0.5V then it will display (Fig.61) as below:
