6. 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.51 & 52) and it will highlighted which prompt you to check the charging
system for the fault.
OR
Testing with electrical load at 1,500 ~ 2,000 RPM
As more electrical accessories, such as lights, rear demister, heater, car stereos, etc. were used; voltage
decreases and this will allow more amperage from the alternator to flow into the battery to compensate for
the added load. This test is to check the alternator’s behavior during loading.
Continue from the previous test (either Fig. 50, 51 or 52); the Analyser will automatically proceed to Load
test at 1,500 to 2,000 rpm. The display will show as below (Fig.53).
Switch ON all electrical loads (Head Lights, Radio, Rear Demister, Heater, etc.).
Note: Air-Condition (mostly mechanical load) should be OFF as it sometimes slowdown the idling
speed of certain cars while it is ON thereby affecting the idling speed charging results.
7. Press key and the display will change to as shown in Fig. 54 below. Rev the engine up around 1,500
to 2,000 RPM by referring to the dashboard meter maintains the engine speed as shown in the example:
(Fig. 54) below.
