    RATING VALUE At the prompt scroll to the battery’s rating value and press ENTER. ADDITIONAL TEST FEATURES SURFACE CHARGE REMOVAL If surface charge is detected while testing in the vehicle, the analyzer will prompt you to turn on the headlights to remove the surface charge. Follow the instructions on the display.

  • Page 7: Starter System Test

    NOTE: A REPLACE BATTERY result may mean a poor connection between the vehicle’s cables and the battery. After disconnecting the vehicle’s battery cables from the battery, retest the battery using the out- of-vehicle test before replacing. STARTER SYSTEM TEST IMPORTANT: When testing older model diesel engines in cold weather, preheating and post heating of the glow plug may skew test results.

  • Page 8: Starter System Problems

    STARTER SYSTEM PROBLEMS With the vehicle lights on If the engine does not crank and the lights dim heavily, check the con- nections to ensure the wiring is clean and in good condition. If the wiring is in good condition, repair or replace the starter. If the engine does not crank and the lights go out, there is probably a poor connection.

  • Page 9: Charging System Test Results

    Note: Some 8 cylinder vehicles and older vehicles idle at a high level after starting. This can allow the analyzer to detect a rev without any action being taken. If this occurs, continue on with the test process. The final test results will not be affected. Step 3: Testing at idle The Micro500 will analyze the charging system output at idle for compari- son to other readings.
  • Page 10 NO CHARGING VOLTAGE The alternator is not providing charging current to the battery. Check the belts to ensure the alternator is rotating with the engine running. If the belts are slipping or broken, replace the belts and retest. Check all connections to and from the alternator especially the connection to the battery.

  • Page 11: Voltmeter

    EXCESS RIPPLE DETECTED One or more diodes in the alternator are not functioning or there is stator damage, which is shown by an excessive amount of AC or ripple current supplied to the battery. Check to ensure the alternator mounting is sturdy and that the belts are in good shape and functioning properly.

    To turn the printer on, briefly press the MODE button. The green STATUS light should turn on. Make sure you are using the Midtronics printer provided with the Micro500. Other printers may not be compatible.
  • Page 15 REPLACING THE MICRO500 BATTERY The Micro500 uses a 9-volt battery to allow testing batteries down to 1 volt. When the battery requires replacing, the display shows “Low Internal Battery, Replace” when you connect to a battery. You should change the battery as soon after the message is displayed as possible.
