AND PANEL
LIGHTS. The
instrument and panel
lights are broken
up into five groups:
Upper Panel
Lights. Lower Panel
Lights, Console Lights,
Coupler Lights
and
Compass
Light.
The instrument
lights
are controlled
by
a 5 amp
circuit breaker
through
a transistorized
dimmer. The dimmer
control is located
in the middle
of the instrument
panel
just above
the pedestal.
In earlier
model airplanes
there is one
control knob
connected
to
a varible resistor
that
controls the
intensity of
the instrument
lights. On
Serial Nos.
7400001
& up
on the 32-260
and Serial
Nos. 7440001
& up on the
32-300 there
is a second
control
knob
connected to
a varible resistor
which
controls the
light intensity
for all the
avionic
equipment. It
may be necessary
to gain access to the
Dimmer Control
Assembly if
so follow
the instructions
given below.
10-68. REMOVAL
