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.

CIGARETTE LIGHTER
~ INSPECTION
When removing the cigarette lighter with the starter
switch set
to the "ACC" position, check to see if there
is any battery voltage applied between the bimetal at
the center
of the case and the case. (Fig. 8-298)
Repair
or replace the cigarette lighter when the result
of inspection is found abnormal.

ANTENNA
AUTO ANTENNA
The auto antenna is interlocked with the radio switch.
The antenna rod goes up when the switch is turned
on, and goes
down when the switch is turned off. The
antenna rod
also goes down when the starter switch
is turned
off with the radio on.
The antenna rod goes up
or down when the cable
connected to the uppermost rod is let out or taken up
by the rotation of motor.
The
motor is provided with a built-in limit switch.
When the up/down
motion of the antenna is com­
pleted, the
limit switch is activated to cut off the
circuit. (Fig. 9A-4)

(1!] INSPECTION
Apply battery voltage to the connector terminals
of the antenna motor to check to see if the
antenna works correctly. (Fig. 9A-5)
Repair the antenna assembly
or replace it when
the results
of inspection are found abnormal.
