STARTER SWITCH
Refer to "START AND CHARGING" of this section.
HEADLIGHT WIPER SWITCH (FIG. 8-
286)
Fig. 8-286
The start and stop
of the wiper motor and the washer
motor can be controlled by operating this switch with
the starter switch on.
The switch returns to its
original position with the
power off when it is released.
(1!] INSPECTION
rfiil Check the continuity between the connector ter­
L:::.I minals while operating the switch. (Fig. 8-287)
Replace the switch when the result of inspection
is
found abnormal.

~ INSPECTION (FIG. 8-290)
Operation test
With the headlight wiper motor connector terminal 6
I C-231 (left) or 61 C-30 I (right) connected to the ba~
(+)terminal, and the termina13IC-23I (left) or 3 ~
(right) to the (-) terminal, check to see if the motor
rotates.
Auto stop operation test
Disconnect the battery(-) terminal while the motor in
rotation, and stop the
motor at any position other than
the auto stop position. Reconnect the disconnected
(-)terminal to 2 C-23 (left) or 2 IC-30 I (right), with 3
IC-23Iconnected to 4 C-23 (for the motor on the right,
3IC-30I connected to 4IC-30I ). Then check to see if
the motor stops at the auto stop position.
Repair
or replace the motor when the result of inspec­
tion is found abnormal.

AUDIO, AUTO ANTENNA, CIGARETTE LIGHTER AND DIGITAL CLOCK
GENERAL DESCRIPTION
The audio circuit is designed for the current to flow through the receiver circuit when the radio switch is turned
on
with the starter switch in" ACC" or "ON". Current runs through the memory circuit of the audio regardless
of the position of the starter switch.
The radio antenna operates in connection
to the radio switch. The antenna rod goes up when the switch is on
and goes
down to be stored in the fender with the switch off. The antenna rod also goes down when the starter
switch is turned
off with radio on.
Refer
to Section 9A "RADIO" for details.
When the cigarette lighter is pushed in
with the starter switch at either "ACC" or "ON" position, a circuit is
formed in the cigarette lighter case
to heat the lighter coil. The cigarette lighter is sprung back to its original
position after the lighter coil
is heated.
