Charging Test and Ripple Test
To enter the charging test, select "Charging Test".
Charging Test will immediately follow right after
Starting/Cranking test. Follow on screen
instructions to proceed.
1. Press ENTER key to start the Charging Test.
NOTE: Do not shut down the engine during
the test. Turn OFF any electrical appliances or
devices in the vehicle during the test as they
will affect the accuracy of the test result.
2. The tester performs the ripple test within 6
seconds and displays the result on screen.
3. After the Ripple Test, tester will automatically
start the Loaded Volt Test.
4. Follow on-screen instructions to perform the
Load Voltage Test. This test requires turning on
loads (radio, heater, light), and revving, then
holding engine to a desired RPM of 2000 -2500.
5. The tester initiates a 15 second countdown
on screen to allow the user to rev up
the engine to 2000-2500 RPM.
6. Charging Test result is displayed on screen.
Follow on-screen instruction to obtain the full
comprehensive Starting and Charging Test results.
NOTE: If no increased RPM detected, it shall be due to
a fault of generator regulator, or connection with battery
has failed. Tester will try 3 times to further detect.
If it still fails, it will skip the increase rev detect and
the test result displays "No Volt Output". See below:

For technical questions, please call 1-888-866-5797.
Check the connection between generator
and battery, then retest.
Charging Test Result:
1. PASS - Alternator output is normal,
no problem detected.
2. FAIL - Charging volt of the charging system is
low. Check the drive belt to see if it's slipping
or running off. Check if the connection between
alternator and battery is normal or not. If both
of the drive belts and the connections are
in good condition, follow the manufacturer's
suggestion to eliminate alternator fault.
3. FAIL- Alternator output volt is high. An internal
regulator is used by the majority of car alternators.
The alternator assembly must be replaced.(Some
older vehicles use external regulators, in this
case directly replace the regulator.) The normal
high volt of the voltage regulator is maximum
14.7±0.5V. If charging volt is too high, it will
overcharge the battery and shorten the battery life.
4. No Volt Output - No alternator volt output is
detected. Check the alternator connection cable
and the belt to verify whether they are normal.
5. Diode Test - The ripple test will determine
whether the diode is normal or not. When ripple
volt is too high, it proves at least one diode is
damaged. Check and replace the diode.
