cranking test
times 1020ms
cranking low
replace 10.13V
After testing is finished do not switch off engine, press the Enter Key to select Charging test.
5.4.3.
Charging System and Rectifier Diode Test.
select charging test and press enter Key
note:- do not shut down the engine during test, all electrical appliances should be switched off, leaving lights etc. on will affect the
test and the accuracy of the results.
the Battery tester will do the following tests in sequence:
ripple test
95mV 14.32V
the ripple test will display the real time ripple, it will also show the ripple volts and charging volt values.
it takes approx. 6 seconds for the ripple test. After the ripple test the tester will automatically start the loaded voltage test.
charging test
loaded testing
*****
loaded Volt testing takes approx. 3 seconds it will then prompt to increase engine speed.
charging test
increase rPm to 2500 r/min
And keep it 5 seconds
Press enter to continue.
increase engine speed to 2500 rev/min or above and maintain for 5 seconds.
the tester will start the charging test after increase in engine speed is detected.

After the test has finished, the tester will display the effective charging volts,ripple test results and charging test results.
charging test
loaded 14.16V
unloaded 14.39V
replace 15mV
charging normal
note: if no increase rev/min detected there is a fault with the alternator or wiring to the battery.
the tester will try 3 more times to detect an increase, if this fails the test result displays “no volt output”
check the wiring between the alternator and battery and retest.
charging test results
a) charging Volt: normal
charging system shows the alternator output as normal.
b) charging Volt: low
charging voltage of the system is low.
check alternator drive belt, check the connections between alternator and battery, if all are in good condition follow the
manufactures procedure to eliminate charging fault.
c) charging Volt: High
the normal maximum high voltage is 14.7+/- 0.5V. if the charging voltage is too high, it will overcharge the battery. this will shorten
the battery life.
d) no Volt: output
no alternator voltage output is detected. check the alternator connection cable and belt.
e) diode test
When ripple volt is too high it shows that at least one diode is damaged. check and replace the diode.
