CIRCUIT BREAKERS AND FUSES.
Most of the electrical circuits in the airplane are protected by
"push-to-reset" circuit breakers mounted on the right side of the
instrument panel. Exceptions to this are the battery contactor
closing (external power) circuit, and clock and optional flight
hour recorder circuits all having fuses mounted near the battery.
Also, the cigar lighter is protected by a manually-reset type
circuit breaker mounted directly on the back of the lighter behind
the pedestal.
When more than one radio is installed, the radio transmitter
relay (which is a part of the radio installation) is protected by the
navigation lights circuit breaker labeled "NAV LIGHTS". If a
malfunction in the navigation lights system causes the circuit
breaker to open, de-activating the lights and transmitter relay,
turn off the navigation light switch and reset the circuit breaker.
This will re-activate the transmitter relay and permit its usage.
Do not turn the switch on again until the malfunction is corrected.
LIGHTING EQUIPMENT.
EXTERIOR LIGHTING.
Conventional navigation lights are located on the wing tips and
top of the rudder. A dual beam landing/taxi light is installed in
the left wing and a flashing beacon is mounted on top of the
vertical fin. Optional lighting includes a strobe light on each wing
tip and two courtesy lights, one under each wing, just outboard of
the cabin door. The courtesy lights are operated by a switch
located on the left rear door post. All exterior lights, except the
courtesy lights, are controlled by rocker type switches on the left
switch and control panel. The switches are "ON" in the up
position and "OFF" in the down position.
The flashing beacon should not be used when flying through
clouds or overcast; the flashing light reflected from water droplets
or particles in the atmosphere, particularly at night, can produce
vertigo and loss of orientation.
The two high intensity strobe lights will enhance anti- collision
protection. However, the lights should be turned off when taxiing
in the vicinity of other aircraft, or during flight through clouds,
fog or haze.
