L0If the driver fastens the seat belt with the ignition switch placed in the “ON” position, the seat belt
switch in the seat belt buckle is turned “ON” to operate the seat belt solenoid in the retractor.
0This will reduce the seat belt rewinding torqe to minimize a sense of oppression given by the belt.
lOwing to the timer function of the ETACS unit, the seat belt solenoid is kept in operation for 30 seconds
after turning off the ignition switch, with due consideration to elimination of the sudden rise in a senseof oppression caused by the belt immediately after the ignition switch is turned off.

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.

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.
