CIRCUIT OPERATION
Voltage is applied at all times to the Light
Switch through the Tail Fuse. With the Light
Switch in
HEAD or PARK, voltage is applied
through the Light Switch, Remote Dimmer, and
INST LP Fuse to the various Instrument Panel
and Console Lights. The lights can be dimmed
using the rheostat in the Light Switch.

TROUBLESHOOTING HINTS
Try the following checks before doing the Sys-
tem Check
.
1 . Check RADIO Fuse .
2 . Check CTSU Fuse or check ARC RADIO
Fuse (if equipped with Remote Control
Head)
.
3 . Check ground 6200 by operating the Cigar
Lighter
.
4 . Check that the Antenna connector and coax-
ial cable are properly connected
.
5 . Adjusting the Radio controls will change the
operation of the sound system
. Consult the
Delco Sound Service Guide for information
regarding the operating of these controls
.
6 . Before troubleshooting a suspect Speaker,
cheek
all connections to that Speaker .
7 . For proper noise diagnosis. take the car out-
side where
signals are strong . Close the
hood. and keep away from metal buildings or
sources of radio interference
.
8 . Ignition noise on FM may indicate a defec-
tive Ignition System
.
9 . Coasted screws or bolts can cause a poor
ground condition
. Scrape ground screw
clean of any paint or varnish
.
Go to System Check for a guide to normal
operation

The Radio Fuse provides power to the Radio
and to the Power Antenna. With the Ignition
Switch in ACCY or RUN, voltage is applied
through the Radio Fuse and the
UEL wire to
the On-Off Switch in the Radio. The circuit is
grounded at 6200. With the On-Off Switch
closed, voltage is applied from the Radio Fuse
to the Radio Switch (Power Antenna), and the
solid state Radio Circuits to ground. Two wires
connect each speaker to the Radio.
The ETR Radio has two inputs that other
models do not have; Display Dim Signal and
ClocklMemory.
The ETR model is an AMIFM Radio that
changes stations electronically. The frequency
of pre-selected stations can be stored
in the
electronic memory. The ETR model also
provides a digital display of time or station
frequency. As in other models, the Light Switch
controls Panel Light dimming. In the
ETR
model, g is also controlled by the Radio
itself by means of the Dim Display Input
Signal.
The ETR model's clock memory and Radio
memory functions are powered at all times
through the CTSY Fuse or through the ARC
RADIO Fuse if equipped with the Remote
Control Head. If power to the ETR model is cut
off by disconnecting the Battery, for example,
the operator must reset the memory functions
when power is restored. The
Subpower Speaker
System consists of a
Subwoofer Amplifier Assembly and two Sub-
woofers. The Amplifier receives power from the
Radio PNK
(143) wire and is grounded at 6200.
The Amplifier Switch is located in the
Sub-
woofer Switch which, when put in the ON posi-
tion, causes the Subwoofer Amplifier to
operate. The eight audio inputs from the
I/P
Speakers and Rear Speakers are sent to the
Subwoofer Amplifier which then outputs an
audio signal to the Subwoofers.
Remote Radio System
The Remote Radio System consists of a mul-
tifunction Remote Control
Head and Data
Transmitter located in the steering wheel, a Slip
Ring and a rotating optical data link in the
steering
colurnn, and an ARC Radio equipped
with a serial data port for remote control.
Power for the electronics is supplied from the
RADIO Fuse, through the
YEL (43) wire,
through the slip ring to the Control Head. The
ground (the
BLKLT BLU (15 1) wire) and Pand
Larnps Power (the GRY (8) wire) are Likewise
supplied to the Control Head through the Slip
Ring assembly.
The Remote Control Head controls the Radio
by generating a unique data word for each oper-
ating function when the button controlling that
function is pressed. The data words are con-
verted from an electronic signal to an optical
signal by the Light Transmitter in the steering
column Cancel Cam. The light signal then
crosses the air gap to the Light Receptor
located in the
Turn Signal Switch where it is
reconverted to
an electronic signal. This signal
is then routed via wire to the Radio, which
responds to the Control signal.

GENERAL DESCRIPTION
Figs. hand 2
The Permanent Magnet (PM) Depressed Park
windshield
(w/s) wiper with remote washer pump sys-
tem consists of a depressed park wiper motor and a
remote washer pump mounted on the washer fluid
container.
Based on the type of control switch used and
whether an optional electronic printed circuit board is
attached in the wiper cover, the system can serve as
either a pulse type wiper-washer system or a standard
type windshield wiper. Pulse timing and "demand"
wash functions are controlled electronically on pulse
windshield wipers.
WIPER AND WSHER OPERAflON
Pulse Windshield Wiper System Fig. 1 Wiper Motor
Electronic logic circuits on a pulse wiper system's
printed circuit board establish all timing and washer
commands. When the WASH switch is pressed, the
washer sprays only during the wiper arm
outwipe and
pulsates operation for 2-1/2 seconds. Then the wiper
dry wipes for nearly
6 seconds before shutting off. See
Pulse Wiper Operation Chart, Fig.
3, for a brief de-
scription of pulse wiper system operation.
If the WASH switch is pressed for more than one
second, a (demand) wash is performed for as long as
the switch is depressed. This wash action is followed by
6 seconds of dry wipes before shut-off. With the control
switch in the
LO or HI speed position, the respective
