    BATTERY TEST RESULTS

    Result On Printer Remedy
    GOOD BATTERY No action is required.
    GOOD - RECHARGE Battery is in a good state.
    Recharge the battery for use.
    • Follow the instruction below when charging and retesting the battery, otherwise the test result may be inaccurate. (See 'Charging and Retesting after charging battery' below.)
    CHARGE & RETEST Battery is not charged properly.
    • Charge and test the battery again.
    • Follow the instruction below when charging and retesting the battery, otherwise the test result may be inaccurate. (See 'Charging and Retesting after charging battery' below.)
    REPLACE BATTERY Replace battery and recheck the charging system.
    • Improper connection between battery and vehicle cables may prompt "REPLACE BATTERY" message. 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 "REPLACE BATTERY" is prompted on Micro 570, replace the battery and recheck the charging system.

    [Charging and Retesting after charging battery] 

    Charging battery 

    Set battery charger to 'Auto Mode' (the Mode that charging current drops as the battery charges) and charge battery until charging current drops down close to zero or the charger alerts with an alarm when charging is complete.

    (Minimum charging time recommended: More than 3 hours in Auto Mode explained above)

    • If battery is not fully charged, battery surface voltage will be high while the amount of current charged (CCA) in battery is low. If the battery is tested in this condition, the tester may misjudge that battery sulfation has occurred as the level of current in battery is too low in comparison with battery voltage.

      * Surface voltage: When battery is charged electrolyte temperature increases and chemical reaction become active resulting in an excessive increase of battery voltage.

      It is known that it takes approximate one day to subside this increased surface voltage completely.

    Testing battery after charging 

    Do not test the battery immediately after charging. Test the battery after the battery surface voltage has subsided as instructed in the following procedure.

    1. When battery charging is complete, install the battery to the vehicle.
    2. Turn IG ON, turn on the headlamps at low beam, and wait for 5 minutes. (Discharge for 5 minutes.)
    3. Turn off the headlamps at IG ON, and wait for 5 minutes. (Wait for 5 minutes.)
    4. Remove +, - cables from the battery and test battery.
      WARNING:
      • Whenever filing a claim for battery, the print out of the battery test results must be attached.

      Starter Test Procedure 

  7. After the battery test, press ENTER immediately for the starter test.

  9. 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

    Result 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 battery level is too low for the test.
    • Charge the battery and retest.
    REPLACE BATTERY Replace battery.
    • If the vehicle cannot be started even though "GOOD BATTERY" is displayed, check wiring for open circuit, battery cable connection and starter, and repair or replace as necessary.
    • If the engine does not crank, check fuel system.
    NOTE:
    • When testing a vehicle with an old diesel engine, the test result may 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 

  10. Press ENTER to begin charging system test.
