CESSNA SECTION 7
MODEL 152 AIRPLANE & SYSTEMS
DESCRIPTIONS
The warning light may be tested by turning on the landing lights and momentarily turning off
the ALT portion of the master switch while leaving the BAT portion turned on.

CIRCUIT BREAKERS AND FUSES

Most of the electrical circuits in the airplane are protected by "push-to reset" circuit breakers
mounted under the engine controls on the instrument panel. The cigar lighter is equipped with
a manually-reset type circuit breaker located on the back of the lighter and a fuse behind the
instrument panel. The control wheel map light (if installed) is protected by the NAV/DOME
circuit breaker, and a fuse behind the instrument panel. Electrical circuits which are not
protected by circuit breakers are the battery contactor closing (external power) circuit, clock
circuit, and flight hour recorder circuit. These circuits are protected by fuses mounted adjacent
to the battery.

GROUND SERVICE PLUG RECEPTACLE

A ground service plug receptacle may be installed to permit the use of an external power
source for cold weather starting and during lengthy maintenance work on the electrical and
electronic equipment

LIGHTING SYSTEMS

EXTERIOR LIGHTING

Conventional navigation lights are located on the wing tips and top of the rudder. Additional
lighting is available and includes a single or dual landing/taxi light mounted in the cowling nose
cap, a flashing beacon located on top of the vertical fin, and a strobe light installed on each
wing tip. Details of the strobe light system are presented in Section 9, Supplements.
All exterior lights are controlled by rocker 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.
