INSPECTION1. Visual and aural checks
Check relay operation, blower motor rotation, light illumina-d
tion, etc. visually or aurally. The flow of current is invisiblebut can be checked by the operation of the parts.
2. Simple checks
For example, if a headlight does not come on and a faultyfuse or poor grounding is suspected, replace the fuse
with a new one or ground the light to the body by a jumper
wire to determine which part is responsible for the problem.3. Checking with instruments
Use an appropriate instrument in an adequate range andread the indication correctly. You must have sufficient
knowledge and experience to handle instruments correctly.
INSPECTION INSTRUMENTS
In inspection, make use of the following instruments.1. Test lights
A test light consists of a 12 V bulb and lead wires. It
is used to check voltages or short circuits.
2. Self-power test light
A self-power test light consists of a bulb, battery and lead
wires connected in series. It is used to check continuity
or grounding.

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.

OPERATION
lWhen the fog light switch is placed in the ON position with the lighting switch in the HEAD positionand the dimmer switch in the LO position, current flows through the dedicated fuse (4) to the coil
of the fog light relay, the fog light switch, the dimmer switch and ground, causing the contacts of
the fog light relay to close.
When the contacts of the fog light relay close, current flows through the dedicated fuse (4) to the
contacts of the fog light relay, the fog lights and ground, causing the fog lights to come on.
lWhen the dimmer switch is placed in the HI position or the lighting switch is placed in the TAIL or
OFF position while the fog lights are ON, current supply to the fog light relay or headlight relay is
cut off. As a result, the contacts of the fog light relay open, and the fog lights go out.
NOTE
The fog lights are included in the light automatic shut-OFF system. (Refer to P.54-37). The indicator lights
are also included in the same system.

OPERATION
0When the lighting switch is placed in the TAILor HEAD position, current flows through the
coil of the tail light relay to the lighting switchand ground, causing the contacts of the tail
light relay to close.
Then current flows through the contacts of thetail light relay to the dedicated fuse
(2) the
individual lights and ground, causing the tail
lights, parking/side marker lights and licenseplate lights to go ON.
<Light automatic shut-OFF system>
lIf the driver’s door is opened after the ignition
switch is turned to “OFF” or the ignition switchis turned to “OFF” after the driver’s door is
opened when the tail lights are lit, the current
which flows to the coil side of the tail light relaywill be cut off by the light automatic shut-off
unit opening the contact point, and the tail light
relay will be turned “OFF’ to automatically shut
off the tail lights, parking and front side marker
lights and license plate light.
lTo turn on the tail lights, parking and front side
marker lights and license plate light again after
they are automatically shut off, turn the lightingswitch to “OFF” once and to “HEAD” again,
or turn the ignition switch to “ACC” or “ON”,
and the automatic shut-OFF will be cancelled
and the current will flow from the light automaticshut-OFF unit to the coil side of the tail light
relay to close the contact point. Thus, the taillight relay will be turned “ON” to turn on the
tail lights, parking and front marker lights and
license plate light.
NOTE
When the lighting switch is at the “HEAD” position,
the light automatic shut-OFF system will be also
activated for the headlights. (Refer to P.54-37.) The
same system will also be activated for the illumina-
tion lights, etc.

OPERATION<Dome
light>l
Battery voltage is always applied to the dome light. When the dome light switch is turned to “ON”,
the dome light will remain lit. After either door is opened if the dome light switch is at “DOOR” position,the dome light will come on.
lWith the dome light turned on (with the ignition switch in the OFF position and with the dome light
switch in the DOOR position), close all doors, and the timer circuit in the ETACS unit will be activatedto gradually vary the voltage for approx. 6 seconds owing to the duty control, and the voltage will
be output to transistor Tr. Since the voltage applied to the dome light gradually decreases, the dome
light will be dimmed.lIf the ignition switch is turned to “ON” while the dome light is lit (while the timer is activated), the
timer circuit will be opened to turn “OFF” transistor Tr. This will immediately turn off the dome light
without dimming.<Foot lights and ignition key illumination
light>-lBattery voltage is always applied to the foot lights and ignition key illumination light.
With the ignition switch in the OFF position, open any door, and all lights will come on.
l
With all lights turned on (with the ignition switch in the OFF position), close all doors, and the timercircuit inside the ETACS unit will operate in the same manner as the dome light to dim all lights.
When the ignition switch is placed in the ON position with all lights turned on (with the timer in operation),the same operation as the dome light will take place.

When the ignition switch is switched to the
ON position, battery voltage is applied (viathe multipurpose fuse (11) and hazard
switch) to the turn-signal and hazard flasher
unit.l
When the turn-signal switch is switched to
the LH position,
Trl (within the flasher unit)
is switched ON and OFF repeatedly.
Then the contacts of the relay 1 (also within
the flasher unit) repeatedly switch from ON
to OFF, causing the turn-signal lights and
turn-signal indicator light LH to flash.l
When the turn-signal switch is switched to
the RH position, Tr2 (within the flasher unit)
is switched ON and OFF repeatedly.Then the contacts of relay 2 (also within
the flasher unit) repeatedly switch from ON
to OFF, causing the turn-signal lights and
turn-signal indicator light RH to flash.2. If one of the bulbs is burned out
lIf the LH (or RH) turn-signal light bulb is
burned-out, the resistance of the turn-signalcircuit as a whole increases, resulting in
