Charging System Test Procedure









CHARGING SYSTEM TEST PROCEDURE
1. Press ENTER to begin charging system test.




2. ENTER button is pressed, the tester displays the actual voltage of generator.
Press ENTER to test the charging system.




3. The MICRO 570 will prompt you to rev the engine until the rev detected. It will then collect the data.




4. Press ENTER.




5. The MICRO 570 will analyze the charging system output at idle for comparison to other readings.




6. The MICRO 570 will detect the amount of ripple from the charging system to the battery. Excessive ripple usually means the stator is damaged or that one or more generator diodes have failed.




7. The MICRO 570 will prompt you to turn on accessary loads. It will then test at idle and prompt you to rev the engine. The analyzer will determine if the charging system can provide enough current for the demands of the vehicle's electrical system.





NOTE:
When asked to turn of the accessory loads, turn of the blower to high(heater), the high beam headlights, and rear defogger. DO NOT use cyclical loads such as air conditioning or wind-shield wipers.

8. After the test, the MICRO 570 will display the idle voltage, load voltage and the state results.
