Battery Test Procedure
- Connect the tester to the battery.
- Red clamp to battery positive (+) terminal.
- Black clamp to battery negative (-) terminal.
CAUTION: Connect clamps securely. If "CHECK CONNECTION" message is displayed on the screen, reconnect clamps securely. - The tester will ask if the battery is connected "IN-VEHICLE" or "OUT-OF-VEHICLE". Make your selection by pressing the arrow buttons; then press ENTER.
- Select CCA and press the ENTER button.
NOTE: CCA : Cold cranking amps, is an SAE specification for cranking battery at -0.4°F (-18°C).
- Set the CCA value displayed on the screen to the CCA value marked on the battery label by pressing up and down buttons and press ENTER.
NOTE: The battery ratings (CCA) displayed on the tester must be identical to the ratings marked on battery label.
- The tester will conduct battery test.
- The tester displays battery test results including voltage and battery ratings.
Refer to the following table and take the appropriate action as recommended by the Micro 570.
Battery Test Results
BATTERY TEST RESULTS REFERENCEResult On Printer Remedy GOOD BATTERY No action is required GOOD RECHARGE Battery is in a good state
Recharge the battery and useCHARGE & RETEST Battery is not charged properly - Charge and test the battery again. (Failure to charge the battery fully may read incorrect measurement value)
REPLACE BATTERY Replace battery and recheck the charging system. - Improper connection between battery and vehicle cables may cause "REPLACE BATTERY", retest the battery after removing cables and connecting the tester to the battery terminal directly prior to replacing the battery.
BAD CELL-REPLACE Charge and retest the battery. - If the Micro 570 recommends "REPLACE BATTERY", replace the battery and recheck the charging system.
WARNING: Whenever filing a claim for battery, the print out of the battery test results must be attached.Starter Test Procedure
- After the battery test, press ENTER immediately for the starter test.
- Start the engine.
- Cranking voltage and starter test results will be displayed on the screen.
Refer to the following table and take the appropriate action as recommended by the Micro 570.
Starter Test Results
STARTER TEST RESULTS REFERENCEResult On Printer Remedy CRANKING VOLTAGE NORMAL System shows a normal starter draw CRANKING VOLTAGE LOW Cranking voltage is lower than normal level - Check starter
CHARGE BATTERY The state of battery charge is too low to test - Charge the battery and retest
REPLACE BATTERY Replace battery - If the vehicle is not started though the battery condition of "GOOD BATTERY" is displayed, check wiring for open circuit, battery cable connection, starter and repair or replace as necessary.
- If the engine does crank, check fuel system.
NOTE: When testing the vehicle with old diesel engines, the test result will not be favorable if the glow plug is not heated. Conduct the test after warming up the engine for 5 minutes.Charging System Test Procedure
- Press ENTER to begin charging system test.
- The tester displays the actual voltage of alternator.
Press ENTER to continue.
- Turn off all electrical load and rev engine for 5 seconds with pressing the accelerator pedal. (Follow the instructions on the screen)
- The message that engine RPM is detected will be displayed on the screen. Press ENTER to continue.
- If the engine RPM is not detected, press ENTER after revving engine.
- The tester will conduct charging system test during loads off.
- Turn on electrical loads (air conditioner, lamps, audio and etc.). Press ENTER to continue.
- The tester will conduct charging system test during loads on.
- Rev engine for 5 seconds with pressing the accelerator pedal. (Follow the instructions on the screen)
- The message that engine RPM is detected will be displayed on the screen. Press ENTER to continue.
- If the engine RPM is not detected, press ENTER after revving engine.
- Turn off electrical loads (air conditioner, lamps, audio and etc.). Turn the engine off.
- Charging voltage and charging system test results will be displayed on the screen.
Shut off engine end disconnect the tester clamps from the battery. Refer to the following table and take the appropriate action as recommended by the Micro 570.
Charging System Test Results
CHARGING SYSTEM TEST RESULTS REFERENCE
| Result On Printer | Remedy |
|---|---|
| CHARGING SYSTEM NORMAL/DIODE RIPPLE NORMAL | Charging system is normal |
| NO CHARGING VOLTAGE | Alternator does not supply charging current to battery
|
| LOW CHARGING VOLTAGE | Alternator does not supply charging current to battery and electrical load to system fully
|
| HIGH CHARGING VOLTAGE | The voltage from alternator to battery is higher than normal limit during voltage regulating.
|
| EXCESS RIPPLE DETECTED | One or more diodes in the alternator is not functioning properly
