lTurn on the ignition switch, and the transistor Tr will be turned on by the timer circuit. This will turn
on the power window relay allowing the power window to be opened and closed.
lTurn the ignition switch from on to off, and the timer circuit will be activated to keep transistor Tr
on for 30 seconds allowing the power window to be opened and closed.
Moreover, if the front door is opened, the timer circuit will stop to turn off the transistor Tr. This
will prevent the window from being opened and closed.

OPERATION
When engine is stoppedWhen the ignition switch is switched to the “ON”
position, electricity flows from the
‘I” terminal of
the generator to the field coil, and at the same time
the charging warning light illuminates.
When engine is being started/has started
When the engine is started, charging voltage is ap-
plied to the ‘I” terminal of the generator, with the
result that the charging warning light is extinguished.
In addition, because battery voltage is applied to
the “S” terminal of the generator, this battery voltage
is monitored at the
IC voltage regulator, thus switch-ing ON and OFF the current to the field coil and
thereby controlling the output voltage of the genera-
tor.
Power is supplied to each load from the “B” terminal
of the generator.
NOTE
The generator relay functions as a back-up for the
flow of electricity to the field coil if there is a discon-
nection or damaged wiring of the charging warning
light.

TROUBLESHOOTING HINTS1. Charging warning light does not go on when
the ignition switch is turned to “ON”, before the
engine starts.l Check the bulb.
2.Charging warning light fails to go off once the
engine starts.l
Check the IC voltage regulator (located with-
in the generator).
3. Discharged or overcharged battery.l
Check the IC voltage regulator (located with-
in the generator).4. The charging warning light illuminates dimly.
l Check the diode (within the combination
meter) for a short-circuit.

OPERATION
L
0For models equipped with the M/T, the clutch
pedal position switch contact is switched OFF
when the clutch pedal is depressed; when the
ignition switch is then switched to the “ST’ posi-tion, electricity flows to the starter relay and
the starter motor, the contact (magnetic switch)of the starter is switched ON and the starter
motor is activated.
NOTEIf the ignition switch is switched to the “ST
position without the clutch pedal being de-
pressed, electricity flows to the starter relay
(coil), the clutch pedal position switch (contacts)
and to ground, with the result that the contacts
of the starter relay are switched OFF, and, be-
cause the power to the starter motor is thereby
interrupted, the starter motor is not activated.lFor models equipped with the
AIT, when the
ignition switch is switched to the “ST’ position
while the selector lever is at the “P” or “N” posi-
tion, the contact (magnetic switch) of the starter
is switched ON and the starter motor is activated.
TROUBLESHOOTING HINTSThe starter motor does not operate at all.
l Check the starter (coil).
lCheck for poor contact at the battery terminals
and starter.l Check Park/Neutral position switch.
l Check clutch pedal position switch.
l Check starter relay.
l Check theft-alarm starter relay.
l Check key reminder switch.

(2)Connect a 12 V battery between S-terminal and M-terminal.(3) Set switch to “ON”, and pinion will move out.
Caution
This test must be performed quickly (in less than 10
seconds) to prevent coil from burning.(4) Check pinion to stopper clearance (pinion gap) with a
feeler gauge.

Broadcasts can be heard but both AM and FM have a lot of noise.

(2)Noise occurs when the engine in running.
Do the following measures eliminate the noise?
@ Tune to a station with a strong signal.
l Extend the antenna completely. (Whip antenna)
l Adjust the sound quality to suppress high tones.
NoIs the radio body ground mounted securely?
Yes
Securely tighten the nuts for the bodyground.

YesClean the antenna plug and ground
wire mounting area. Mount the anten-
na securely. On a vehicle with a motor
antenna, check the antenna itself. (Re-fer to E-1, 2.)
If there is more noise than other radios, consult a servicecenter

Repair or replace electricalcomponents.
Return parts or wiring to
their proper position.
Caution
1.Connecting a high tension cable to the noise
filter may destroy the noise filter and shouldnever be done.
2.Check that there is no external noise. Since
failure to do this may result in misdiagnosis
due to inability to identify the noise source,
this operation must be performed.3. Noise prevention should be performed by
suppressing strong sources of noise step
by step.
NOTE
1. Condenser
The condenser does not pass D.C. current, butas the number of waves increases when it
passes A.C. current, impedance (resistanceagainst A.C.) decreases, and current flow is
facilitated. A noise suppressing condenser
which takes advantage of this property is in-
serted between the power line for the noise
source and the ground. This suppresses noiseby grounding the noise component (A.C. or
pulse signal) to the body of the vehicle.
2. Coil
The coil passes D.C. current, but impedance
rises as the number of waves increases relativeto the A.C. current. A noise suppressing coil
which takes advantage of this property is in-
serted into the power line for the noise source,
and works by preventing the noise componentfrom flowing or radiating out of the line.

Ground parts by bonding.
Cases where the problem
is not eliminated by a single
response to one area are
common, due to several
bodypartsbeing
imperfectly grounded.
