MAINTENANCE MANUAL
PASSENGER COMPARTMENT
All lighting is 24 Vdc.
1. Courtesy / Rear Baggage Area Lighting
A. Description
Cabin courtesy, rear baggage area and forward baggage compartment lighting is powered through
an in-line 5 amp fuse from the battery bus. Two switches, an upper and lower, are actuated by the
cabin entrance door. One half of the lower switch controls the cabin courtesy lighting, while the
other half and the upper portion of the switch provides door ajar warning power to the annunciator
panel. The cabin entrance lighting circuit is controlled by a five minute “one-shot” timer to prevent
unnecessary battery discharge if the door is left open unattended. The lights are located to ensure
the entrance steps are illuminated. The forward baggage compartment light is controlled by a switch
in the forward baggage compartment that is activated when the baggage compartment door is
opened.
