NOTE
When asked to turn on the accessory loads, turn on
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.

After the test, the MICRO 570 will display the idle volt-
age, load voltage and the state results.
LOAD OFF: 14.28V
LOAD ON : 14.12V

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

DESCRIPTION
EDCABFCE
The conventional internal voltage detection type alterna-
tor controls the charging voltage regardless of the battery
condition and according to the external load change so
that it sometimes causes battery under or over charging
or causes flickering of meters and lamps due to ripples of
generated voltage resulting from load fluctuation. The fig-
ure below show the internal circuits of the alternator and
voltage regulator.

ON-VEHICLE INSPECTION
EE8EC6C0
CAUTION
• Check that the battery cables are connected
to the correct terminals.
• Disconnect the battery cables when the bat-
tery is given a quick charge.
• Do not perform tests with a high voltage insu-
lation resistance tester.
• Never disconnect the battery while the engine
is running.
CHECK BATTERY VOLTAGE
1.
After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the en-
gine, turn the ignition switch ON and turn on the elec-
trical system (headlamp, blower motor, rear defogger
etc.) for 60 seconds to remove the surface charge.
2.
Turn the ignition switch OFF and turn off the electrical
systems.
3.
Measure the battery voltage between the negative (-)
and positive (+) terminals of the battery.
Standard voltage : 12.5~12.9V at 20 C (68 C)
If the voltage is less than specification, charge the
battery.
CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
1.
Check that the battery terminals are not loose or cor-
roded.
2.
Check the fusible link and fuses for continuity.

INSPECT DRIVE BELT
1.
Visually check the belt for excessive wear, frayed
cords etc.
If any defect has been found, replace the drive belt.
NOTE
Cracks on the rib side of a belt are considered accept-
able. If the belt has chunks missing from the ribs, it
should be replaced.

2.
Using a belt tension gauge, measure the drive belt
tension.
VISUALLY CHECK ALTERNATOR WIRING AND
LISTEN FOR ABNORMAL NOISES
1.
Check that the wiring is in good condition.
2.
Check that there is no abnormal noise from the alter-
nator while the engine is running.
CHECK DISCHARGE WARNING LIGHT CIRCUIT
1.
Warm up the engine and then turn it off.
2.
Turn off all accessories.
3.
Turn the ignition switch "ON". Check that the dis-
charge warning light is it.
4.
Start the engine. Check that the light goes off.
If the light does not go off as specified, troubleshoot the
discharge light circuit.

VOLTAGE DROP TEST OF ALTERNATOR OUTPUT
WIRE
This test determines whether or not the wiring between the
alternator "B" terminal and the battery (+) terminal is good
by the voltage drop method.
PREPARATION
1.
Turn the ignition switch to "OFF".
NOTE
To find abnormal conditions of the connection, actions
should not be taken on the two terminals and each
connection during the test.
2.
Connect a digital voltmeter between the alternator "B"
terminal and battery (+) lead wire to the battery (+)
terminal. Connect the (+) lead wire of the voltmeter to
the "B" terminal and the (-) lead wire to the battery (+)
terminal.

CONDITIONS FOR THE TEST
1.
Start the engine.
2.
Switch on the headlamps, blower motor and so on.
And then, read the voltmeter under this condition.
RESULT
1.
The voltmeter may indicate the standard value.
Standard value: 0.2V max.
2.
If the value of the voltmeter is higher than expected
(above 0.2V max.), poor wiring is suspected. In this
case check the wiring from the alternator "B" terminal
to the fusible link to the battery (+) terminal. Check
for loose connections, color change due to an over-
heated harness, etc.
Correct them before testing
again.
3.
Upon completion of the test, set the engine speed at
idle. Turn off the head lamps, blower motor and the
ignition switch.
