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.

DESCRIPTION
The charging system included a battery, an alternator with a built- in regulator, and the charging indicator light and
wire.
The Alternator has built- in diodes, each rectifying AC current to DC current.
Therefore, DC current appears at alternator "B" terminal.
In addition, the charging voltage of this alternator is regulated by the battery voltage detection system.
The alternator is regulated by the battery voltage detection system. The main components of the alternator are the
rotor, stator, rectifier, capacitor brushes, bearings and V- ribbed belt pulley. The brush holder contains a built- in
electronic voltage regulator.

ON-VEHICLE INPECTION
a.Check that the battery cables are connected to the correct terminals.
b. Disconnect the battery cables when the battery is given a quick charge.
c. Never disconnect the battery while the engine is running.
CHECK BATTERY VOLTAGE
1.If 20 minutes have not passed since the engine was stopped, turn the ignition switch ON and turn on the electrical
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°F)
If the voltage is less than specification, charge the battery.
CHECK THE BATTERY TERMINALS AND FUSES
1.Check that the battery terminals are not loose or corroded.
2. Check the fuses for continuity.
INSPECT DRIVE BELT
Visually check the belt for excessive wear, frayed cords etc.
If any defect has been found, replace the drive belt.
Cracks on the rib side of a belt are considered acceptable. If the belt has chunks missing from the ribs, it should
be replaced.
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 alternator 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 discharge warning light is lit.
4. Start the engine. Check that the light is lit.
If the light does not go off as specified, troubleshoot the discharge light circuit.
INSPECT CHARGING SYSTEM
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

TEST
1.Check to see that the voltmeter reads as the same value as the battery voltage. If the voltmeter reads 0V, and the
open circuit in the wire between alternator "B" terminal and battery ( - ) terminal or poor grounding is suspected.
2. Start the engine and turn on the headlamps.
3. Set the headlamps to high beam and the heater blower switch to HIGH, quickly increase the engine speed to 2,500
rpm and read the maximum output current value indicated by the ammeter.
After the engine start up, the charging current quickly drops.
Therefore, the above operation must be done quickly to read the maximum current value correctly.
RESULT
1.The ammeter reading must be higher than the limit value. If it is lower but the alternator output wire is in good
condition, remove the alternator from the vehicle and test it.
Limit value : 70Ë of the rated current
a.The nominal output current value is shown on the nameplate affixed to the alternator body.
b. The output current value changes with the electrical load and the temperature of the alternator itself.
Therefore, the nominal output current may not be obtained. If such is the case, keep the headlamps on the
cause discharge of the battery, or use the lights of another vehicle to increase the electrical load.
The nominal output current may not be obtained if the temperature of the alternator itself or ambient
temperature is too high.
In such a case, reduce the temperature before testing again.
2. Upon completion of the output current test, lower the engine speed to idle and turn off the ignition switch.
3. Disconnect the battery ground cable.
4. Remove the ammeter and voltmeter and the engine tachometer.
5. Connect the alternator output wire to the alternator "B" terminal.
6. Connect the battery ground cable.
REGULATED VOLTAGE TEST
The purpose of this test is to check that the electronic voltage regulator controls voltage correctly.
PREPARATION
1.Prior to the test, check the following items and correct if necessary.
Check that the battery installed on the vehicle is fully charged. The battery checking method is described in the
section "Battery".
Check the alternator drive belt tension. The belt tension check method is described in the section "Inspect drive
belt".
2. Turn ignition switch to "OFF".
3. Disconnect the battery ground cable.
4. Connect a digital voltmeter between the "B" terminal of the alternator and ground. Connect the (+) lead of the
voltmeter to the "B" terminal of the alternator. Connect the ( - ) lead to good ground or the battery ( - ) terminal.
5. Disconnect the alternator output wire from the alternator "B" terminal.

6.Connect a DC ammeter (0 to 150A) in series between the "B" terminal and the disconnected output wire.
Connect the ( - ) lead wire of the ammeter to the disconnected output wire.
7. Attach the engine tachometer and connect the battery ground cable.
TEST
1.Turn on the ignition switch and check to see that the voltmeter indicates the following value.
Voltage: Battery voltage
If it reads 0V, there is an open circuit in the wire between the alternator "B" terminal and the battery and the battery
( - ) terminal.
2. Start the engine. Keep all lights and accessories off.
3. Run the engine at a speed of about 2,500 rpm and read the voltmeter when the alternator output current drops to
10A or less
RESULT
1.If the voltmeter reading agrees with the value listed in the regulating voltage table below, the voltage regulator is
functioning correctly. If the reading is other than the standard value, the voltage regulator or the alternator is faulty.
REGULATING VOLTAGE TABLE

80 (176) 14.2 ~ 15.4
14.0 ~ 15.0
13.7 ~ 14.9
13.5 ~ 14.7
2. Upon completion of the test, reduce the engine speed to idle, and turn off the ignition switch.
3. Disconnect the battery ground cable.
4. Remove the voltmeter and ammeter and the engine tachometer.
5. Connect the alternator output wire to the alternator "B" terminal.
6. Connect the battery ground cable.

8.Clean the inside surface of the terminal clamps with a suitable battery cleaning tool. Replace damaged or frayed
cables and broken terminal clamps.
9. Install the battery in the vehicle.
10. Connect the cable terminals to the battery post, making sure tops of the terminals are flush with the tops of the
posts.
11. Tighten the terminal nuts securely.
12. Coat all connections with light mineral grease after tightening.
When batteries are being charged, an explosive gas forms beneath the cover of each cell. Do not smoke
near batteries being charged or which have recently been charged. Do not break live circuit at the terminals
of batteries being charged.
A spark will occur when the circuit is broken. Keep open flames away form battery.
