dAbGENERATOR PULLEY REMOVAL
(1) Remove the bolts.
(2) Insert plain screwdriver between front bracket and
stator core and pry downward.
Caution
Do not insert screwdriver too deep, as there is
danger of damage to
stator coil.

WireZ6EN087!(3) Clamp the rotor in a vise with soft jaws.
(4) After removing the nut, remove the pulley and front
bracket from the rotor.
AB,STATOR / REGULATOR AND BRUSH HOLDER
REMOVAL
(1) When removing the stator, unsolder stator lead wirefrom the main diode of the rectifier.
(2) When removing the brush holder, unsolder it from
the rectifier.
Caution
(1) When soldering or unsoldering, be careful to
make sure that heat of soldering iron is not
transmitted to diodes for a long period. Finish
soldering or unsoldering in as short a time
as possible.
(2) Be careful that no undue force is exerted to
leads of diodes.REASSEMBLY SERVICE POINT
FAdROTOR ASSEMBLY INSTALLATION
Before rotor is attached to rear bracket, insert wire through
small hole made in rear bracket to lift brush. After rotor
has been installed, remove the wire.

\23ELOllINSPECTION
ROTOR
(1) Check field coil for continuity. Check to ensure that there
is continuity between slip rings.If resistance is extremely small, it means that there is
a short. If there is no continuity or if there is short circuit,
replace rotor assembly.
Resistance value : Approx. 3-5 Q
(2) Check field coil for grounding. Check to ensure that thereis no continuity between slip ring and core. If there is
continuity, replace rotor assembly.
STATOR
(1) Make continuity test on stator coil. Check to ensure that
there is continuity between coil leads.
If there is no continuity, replace
stator assembly.
(2) Check coil for grounding. Check to ensure that there is
no continuity between coil and core. If there is continuity,
replace stator assembly.
RECTIFIERS
(1) Positive Rectifier Test
Check for continuity between positive rectifier and stator
coil lead connection terminal with a circuit tester. If there
is continuity in both directions, diode is shorted. Replace
rectifier assembly.

(2) Negative Rectifier Test
Check for continuity between negative rectifier and stator
coil lead connection terminal. If there is continuity in both
directions, diode is shorted, and rectifier assembly must
be replaced.
(3) Diode Trio Test
Check three diodes for continuity by connecting an amme-
ter to both ends of each diode. If there is no continuity
in both directions, diode is faulty and
heatsink assembly
must be replaced.
BRUSH REPLACEMENT
(1) Replace brush by the following procedures if it has been
worn to limit line.
(2) Unsolder pigtail and remove old brush and spring.
(3) Install brush spring and new brush in brush holder.(4) Insert the brush to where there is a space 2 to 3 mm
(.079 to .118 in.) between the limit line and the end of
the brush holder.

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 render-
ing 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
TSupplemental Re-
straint System (SRS) and GROUP 00 -Maintenance Service before beginning any service or maintenance of any com-
ponent of the SRS or any
SRS-related component.
NOTE
The SRS includes the following components: impact sensors, SRS diagnosis unit, SRS warning light, air bag module, clock spring
and interconnecting wiring. Other SRS-related components (that may
h,a”” to be removed/installed in connection with SRS serviceor maintenance) are indicated in the table of contents by an asterisk ( ).

BATTERY INSPECTION
BAlTERY VISUAL CHECK (1)
The battery contains a visual test indicator which gives blue
signal when an adequate charge level exists, and white signal
when charging is required.
BAlTERY VISUAL CHECK (2)
Make sure ignition switch is in Off position and all battery
feed accessories are Off.
1.Disconnect ground cable from battery before disconnecting
(+) cable.
2. Remove battery from vehicle.
CautionCare should be taken in the event battery case is
cracked or leaking to protect hands from the electro-
lyte. A suitable pair of rubber gloves (not the house-hold type) should be worn when removing battery
by hand.
3.Inspect battery carrier for damage caused by loss of acid
from battery. If acid damage is present, it will be necessaryto clean area with a solution of clean warm water and
baking soda. Scrub area with a stiff bristle brush and wipe
off with a cloth moistened with ammonia or baking soda
in water.
