ALTERNATOR OUTPUT LINE VOLTAGE DROP TEST
Alternator
Terminal BVoltmeterAmmeter
Battery
+-
+-
This test determines whether the wiring from the
alternator “B” terminal to the battery (+) terminal
(including the fusible line) is in a good condition
or not.
(1) Always be sure to check the following before
the test.
DAlternator installation
DAlternator drive belt tension
(Refer to GROUP 11 - On-vehicle Service.)
DFusible link
DAbnormal noise from the alternator while
the engine is running
(2) Turn the ignition switch to the “LOCK” (OFF)
position.
(3) Disconnect the negative battery cable.
(4) Disconnect the alternator output wire from the
alternator “B” terminal and connect a DC test
ammeter with a range of 0 - 100 A in seriesbetween the “B” terminal and the disconnected
output wire. (Connect the (+) lead of the
ammeter to the “B” terminal, and then connect
the ( - ) lead of the ammeter to the disconnected
output wire.)
NOTE
An inductive-type ammeter which enables
measurements to be taken without
disconnecting the alternator output wire should
be recommended. Using this equipment will
lessen the possibility of a voltage drop caused
by a loose “B” terminal connection.
(5) Connect a digital-type voltmeter between the
alternator “B” terminal and the battery (+)
terminal. (Connect the (+) lead of the voltmeter
to the “B” terminal and the connect the ( - ) lead
of the voltmeter to the battery (+) cable.)

ENGINE ELECTRICAL -Charging System16-6
This test determines whether the alternator output
current is normal.
(1) Before the test, always be sure to check the
following.
DAlternator installation
DBattery (Refer to GROUP 54 - Battery.)
NOTE
The battery should be slightly discharged.
The load needed by a fully-charged battery
is insufficient for an accurate test.
DAlternator drive belt tension
(Refer to GROUP 11 - On-vehicle Service.)
DFusible link
DAbnormal noise from the alternator while
the engine is running.
(2) Turn the ignition switch to the “LOCK” (OFF)
position.
(3) Disconnect the negative battery cable.
(4) Disconnect the alternator output wire from the
alternator “B” terminal. Connect a DC test
ammeter with a range of 0 - 100 A in series
between the “B” terminal and the disconnected
output wire. (Connect the (+) lead of the
ammeter to the “B” terminal. Connect the ( - )
lead of the ammeter to the disconnected output
wire.)
Caution
Never use clips but tighten bolts and nuts
to connect the line. Otherwise loose
connections (e.g. using clips) will lead to
a serious accident because of high current.
NOTE
An inductive-type ammeter which enables
measurements to be taken without
disconnecting the alternator output wire should
be recommended.
(5) Connect a voltmeter with a range of 0 - 20 V
between the alternator “B” terminal and the
earth. (Connect the (+) lead of the voltmeter
to the “B” terminal, and then connect the ( - )
lead of the voltmeter to the earth.)
(6) Connect the negative battery cable.
(7) Connect a tachometer or the MUT-II.
(Refer to GROUP 11 - On-vehicle Service.)
(8) Leave the hood open.
(9) Check that the reading on the voltmeter is equal
to the battery voltage.
NOTE
If the voltage is 0 V, the cause is probably
an open circuit in the wire or fusible link between
the alternator “B” terminal and the battery (+)
terminal.(10)Turn the light switch on to turn on headlamps
and then start the engine.
(11) Immediately after setting the headlamps to high
beam and turning the heater blower switch to
the high revolution position, increase the engine
speed to 2,500 r/min and read the maximum
current output value displayed on the ammeter.
Limit: 70 % of normal current output
NOTE
DFor the nominal current output, refer to the
Alternator Specifications.
DBecause the current from the battery will
soon drop after the engine is started, the
above step should be carried out as quickly
as possible in order to obtain the maximum
current output value.
DThe current output value will depend on
the electrical load and the temperature of
the alternator body.
DIf the electrical load is small while testing,
the specified level of current may not be
output even though the alternator is normal.
In such cases, increase the electrical load
by leaving the headlamps turned on for
some time to discharge the battery or by
using the lighting system in another vehicle,
and then test again.
DThe specified level of current also may not
be output if the temperature of the alternator
body or the ambient temperature is too
high. In such cases, cool the alternator and
then test again.
(12)The reading on the ammeter should be above
the limit value. If the reading is below the limit
value and the alternator output wire is normal,
remove the alternator from the engine and
check the alternator.
(13)Run the engine at idle after the test.
(14)Turn the ignition switch to the “LOCK” (OFF)
position.
(15)Remove the tachometer or the MUT-II.
(16)Disconnect the negative battery cable.
(17)Disconnect the ammeter and voltmeter.
(18)Connect the alternator output wire to the
alternator “B” terminal.
(19)Connect the negative battery cable.

EXAMPLES OF ABNORMAL WAVEFORMS
NOTE
1. The size of the waveform patterns differs largely, depending on the adjustment of the variable knob
on the analyzer.
2. Identification of abnormal waveforms is easier when there is a large output current (regulator is not
operating). (Waveforms can be observed when the headlamps are illuminated.)
3. Check the conditions of the charging warning lamp (illuminated/not illuminated). Also, check the charging
system totally.

WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to personal
injury or death to service personnel (from inadvertent firing of the air bag) or to the driver and passenger (from rendering
the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any SRS-related
component.
NOTE
The SRS includes the following components: SRS-ECU, SRS warning lamp, air bag module, clock spring and interconnecting
wiring. Other SRS-related components (that may have to be removed/installed in connection with SRS service or maintenance) are
indicated in the table of contents by an asterisk (*).

STEERING -On-vehicle Service37A-8
2. Move ball joint stud several times and install nut on stud.
Measure ball joint turning torque with special tool.
Standard value: 1.0 - 3.0 N·m
3. When the turning torque exceeds the standard value,
replace tie rod end.
4. When the turning torque is under the standard value,
check ball joint for end play or ratcheting. If none of these,
the joint is still serviceable.
STATIONARY STEERING EFFORT CHECK
1. With the vehicle stopped on a flat, paved surface, turn
the steering wheel to the straight ahead position.
2. Start the engine and set it to 1,000±100 r/min.
3. Attach a spring balance to the outer circumference of
the steering wheel and measure the steering force
required to turn the steering wheel from the straight ahead
position to the left and right (within a range of 0.9 turns).
Also check to be sure that there is no significant fluctuation
of the required steering force.
Standard value:
Steering effort32 N or less
Fluctuation allowance6.0 N or less
4. If the standard values are not met, check and adjust
the related parts.
CHECKING STEERING WHEEL RETURN TO
CENTRE
To make this test, conduct a road test and check as follows.
1. Make both gradual and sudden turns and check the
steering “feeling” to be sure that there is not difference
in the steering force required and the wheel return between
left and right turns.
2. At a speed of 35 km/h, turn the steering wheel 90_and
release the steering wheel after 1 or 2 seconds. If the
steering wheel then returns 70_or more, the return can
be judged to be satisfactory.
NOTE
There will be a momentary feeling or “heaviness” when
the wheel is turned quickly, but this is not abnormal. (This
is because the oil pump discharge amount is especially
apt to be insufficient during idling.)
DRIVE BELT TENSION CHECK
