BATTERY TEST RESULTS

RESULT ON PRINTERREMEDY
Good batteryNo action is required
Good rechargeBattery is in a good state
Recharge the battery and use
Charge & RetestBattery 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. And then, test results may cause "REPLACE BATTERY", replace battery and recheck the charging system

BATTERY TEST RESULTS

WARNINGWhenever filing a claim for battery, the print out of the battery test results must be attached.

  1. After the battery test, press ENTER immediately for the starter test.
  2. After pressing ENTER key, start the engine.
  3. Cranking voltage and starter test results will be displayed on the screen. Take a relevant action according to the test results by referring to the starter test results as given below.
  4. To continue charging system test, press ENTER.

STARTER TEST RESULTS

RESULT ON PRINTERREMEDY
Cranking voltage normalSystem shows a normal starter draw
Cranking voltage lowCranking voltage is lower than normal level
=> Check starter
Charge batteryThe 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 and fully charged" 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.

CHARGING SYSTEM TEST RESULTS

RESULT ON PRINTERREMEDY
Charging system normal/Diode ripple normalCharging system is normal
No charging voltageAlternator does not supply charging current to battery
=> Check belts, connection between alternator and battery Replace belts or cable or alternator as necessary
Low charging voltageAlternator does not supply charging current to battery and electrical load to system fully
=> Check belts and alternator and replace as necessary
High charging voltageThe voltage from alternator to battery is higher than normal limit during voltage regulating.
=> Check connection and ground and replace regulator as necessary
=> Check electrolyte level in the battery
Excess ripple detectedOne or more diodes in the alternator is not functioning properly
=> Check alternator mounting and belts and replace as necessary
