3.8 Pulley and pulley Protective cap

Assembly:

Insert the solid pulley in to the rotor shaft, use the

assembly tool as described in point 1.1. Hold the

alternator pulley by hand or with a pulley holder,

using the serration tool overrunning alternator

pulley can be screwed into the alternator shaft.

Protective cap can be assembled by hand

pressing on to the pulley.

NOTE

It is not permitted to operate the over running

alternator pulley without protective cap.

REFITTMENT:

1.Locate the alternator on its mounting bracket

and fit the three mounting bolts with specified

tightening torque.

2.Fit the Alternator belt.

3.Connect the electrical connection.

ALTERNATOR TESTING PROCEDURES

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.

1. Turn the ignition switch to "OFF".

2. Disconnect the output wire from the alternator

"B" terminal. Connect the (+) lead wire of

ammeter to the "B" terminal of alternator and

the (-) lead wire of am- meter to the output

wire. Connect the (+) lead wire of voltmeter to

the "B" terminal of alternator and the (-) lead

wire of voltmeter to the (+) terminal of battery.

TEST

1. Start the engine.

2. Turn on the headlamps and blower motor, and

set the engine speed until the ammeter indicates

20A. And then, read the voltmeter at this time.

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 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 headlamps, blower

motor and the ignition switch.

OUTPUT CURRENT TEST

This test determines whether or not the alternator

gives an output current that is equivalent to the

normal output.

PREPARATION

1. Prior to the test, check the following items and

correct as necessary. Check the battery

installed in the vehicle to ensure that it is good

condition. The battery checking method is
