Kia Carnival (2009+). Instruction — part 218

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.

When asked to turn of the accessory loads, turn of the blower to high(heater), the high beam beadlights, 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.

CHARGING SYSTEM TEST RESULTS

RESULT ON PRINTER

REMEDY

Charging system normal/Diode ripple normal Charging system is normal

No charging voltage

Generator does not supply charging current to battery
=> Check belts, connection between generator and battery
Replace belts or cable or generator as necessary

Low charging voltage

Generator does not supply charging current to battery and electrical
load to system fully
=> Check belts and generator and replace as necessary

High charging voltage

The voltage from generator 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 detected

One or more diodes in the generator is not functioning properly
=> Check generator mounting and belts and replace as necessary
