11-101. SWITCH AND CIRCUIT BREAKER PANEL. Removal of the trim panel is
necessary to service the switches and circuit breakers on the panel assembly. With the trim
panel removed, it is now possible to remove or install new switches or circuit breakers by
removing the panel assembly that they are mounted on. Use caution when working on these
panels that other parts and wiring are not damaged. The voltage regulator selector switch
and master switch must have lock washers installed on each terminal as required.
11-102. OVERHEAD SWITCH PANEL. Removal of the overhead switches does not require
the removal of the trim panel. The switches are held in place with clips and can be removed
by pulling them out and replaced by pushing them back into the clips located in the panel
assembly.
11-103. TRIM INDICATOR LIGHTS.
11-104. REPLACEMENT OF TRIM INDICATOR LIGHTS. The trim indicator lights are
located in the control pedestal, between the indicator units. The light bulbs may be replaced
by first removing the aileron trim control knob by pushing out the roll pin that secures the
knob. Then remove the trim panel from the face of the pedestal by removing panel
attachment screws. Each bulb is rotated from its socket. Replace bulbs and attachments in
reverse order of removal.
