Press the ENTER button for cranking test. Start the engine when prompted. The tester displays the decision on the starter system, cranking voltage, and cranking time in seconds. Press ENTER button to proceed with the charging system test, Print button to print the test.
NOTE: Before starting the test, inspect the alternator drive belt. A belt that is glazed or worn, or lacks the proper tension, will prevent the engine from achieving the rpm levels needed for the test. After an in-car battery test, the display alternates between the battery test results and the message PRESS FOR CRANKING TEST.
Charging System Test:
Once you have completed an in-vehicle test, the display alternates between the battery test results and the message press ENTER for charging test. Press ENTER to proceed with the charging test. Follow the on-screen prompts to Rev the engine. Turn on high beams headlights and the blower fan. Rev engine with loads on. Idle engine and turn off loads. The Charging System decision is displayed at the end of the procedure.
Battery Tester Results:
- GOOD BATTERY: The battery is in good condition.
- GOOD-RECHARGE: The battery is in good condition but low current. Fully charge the battery and return it to service.
- CHARGE & RETEST: Fully charge the battery and retest. Failure to fully charge the battery before testing may result in inaccurate results. If you still get CHARGE & RETEST message after you fully charge the battery, replace it.
- REPLACE BATTERY: The battery is almost dead or the connection between the battery and battery cable is poor. Replace the battery and retest; or disconnect the battery cables and retest the battery using the out-of-vehicle test before replacing it.
- BAD CELL-REPLACE: The battery may be damaged such as broken cell or short circuit. Replace the battery and retest.
Cranking Test Results:
- CRANKING NORMAL: The starter voltage is normal and the battery is fully charged.
- LOW VOLTAGE: The starter voltage is low and the battery is fully charged.
- CHARGE BATTERY: The starter voltage is low and the battery is discharged. Fully charge the battery and repeat the starter system test.
- REPLACE BATTERY: Battery must be replaced before the starting system can be tested.
- NO START: No vehicle start detected.
- CRANKING SKIPPED: A start was not detected.
Charging System Test Results:
- NO PROBLEMS: System is showing normal output from the alternator.
- NO OUTPUT: No alternator output detected. Check all connections to and from the alternator, especially the connection to the battery. If the connection is loose or heavily corroded, clean or replace the cable and retest. If the belts and connections are in good working condition, replace the alternator. (Older vehicles use external voltage regulators, which may require only replacement of the voltage regulator.)
- LOW OUTPUT: Alternator not providing sufficient to power the system's electrical loads and charge the battery. Check the belts to ensure the alternator is rotating with the engine running. Replace broken or slipping belts and retest. Check the connections from the alternator to the battery. If the connection is loose or heavily corroded, clean or reparable the cable and retest.
- HIGH OUTPUT: Alternator voltage output exceeds the normal limits. Make sure there are no loose connections and the ground connection is normal. If there are no connection problems, replace the regulator. Most alternators have a built-in regulator that requires replacing the alternator. In older vehicles that use external voltage regulators, you may need to replace only the voltage regulator.
- EXCESSIVE RIPPLE: Excessive AC ripple detected. One or more diodes in the alternator are not functioning or there is stator damage.
If you are testing inside a vehicle, make sure all accessory loads are cut off, the key is not in the ON position and the doors are closed.
In order to make the test result more accurate, please notice the followings before testing:
1. Turn off all electronic equipment.
2. When you completed charging, please wait for half an hour to test.
3. New battery need to be full-charged, and also need to wait for half an hour to test.
4. When connect the claps to the battery, please make sure the claps are perpendicular to the terminal post.
