GENERAL DESCRIPTION
The standard Camaro instrument cluster assembly con-
sists
of two
circular units which house
the
speedometer
and fuel gauge assemblies.
The oil
pressure, left-hand
directional
and
brake warning indicators
are
located
in
the face
of the
speedometer bezel while generator,
tem-
perature
and
right-hand directional indicators are grouped
with
the
fuel gauge unit.
The
high beam indicator
is
located between
the
cluster bezels.
A special instrumentation package
is
available with
the
eight-cylinder engine
and
center floor console combina-
tion.
The
special cluster includes:
a
clock; coolant
temperature,
oil
pressure, fuel
and
ammeter gauges,
mounted forward
on the
seat separator console;
a ta-
chometer
in the
right circular housing
of the
dash
in-
strument cluster; and
a low
fuel level indicator replacing
the
oil
pressure indicator lamp
in the
instrument cluster.
The instruments
and
gauges,
may be
serviced only
after
the
instrument cluster
is
removed from
the
vehicle.
Indicator
and
cluster lamps except
for the
high beam
indicator
may be
replaced without removing
the
cluster
assembly. Partial cluster removal
is
necessary when
replacing
the
high beam indicator due
to its
proximity
to
the upper brace
rod
anchor plate.
The
bulbs
are in-
stalled
in
plastic sockets which lock into
the
cluster
housing and make contact with
the
printed circuit.
A
low
level fuel warning system
is a
special feature
available with
the
floor console gauge pack. This
sys-
tem includes
an
indicator lamp
in the
dash cluster and
a
semi-conductor unit senses
the
change
in
electrical
re-
sistance
of the
fuel system circuitry
as
variations
in
fuel level occur.
The
sensing device
is
replaced
as a
unit
if
found defective.
The brake warning light serves
a
dual purpose.
It
functions
as an
indicator when
the
parking brake
is ap-
plied
and
also
if
there
is a
malfunction (loss
of
hydraulic
pressure)
in the
brake system. Switches which provide
the signal
to
operate
the
light
are
located
at the
parking
brake assembly
and at the
brake master cylinder
in the
hydraulic lines. Service
of the
brake pressure differ-
ential switch unit
is
covered
in
Section
5 of
this manual.
Regular maintenance
is not
required on
the
instrument
cluster
or its
components other than maintaining clean,
tight electrical connections, replacing defective parts
and keeping
the
speedometer properly lubricated.
