CESSNA SECTION 7
MODEL 182T AIRPLANE & SYSTEMS DESCRIPTION
CIRCUIT BREAKERS AND FUSES
Except for the autopilot breaker, which is a "pull-type" breaker,
all circuit breakers inside the airplane are of the "push to reset" or
“switch/breaker” type. The power distribution module (J-Box) uses
either "push to reset" circuit breakers. One glass type fuse is also
used to provide power to the clock
GROUND SERVICE PLUG RECEPTACLE
A ground service receptacle plug is integral to the power
distribution module and allows the use of an external power source
for cold weather starting, and during lengthy maintenance work on
electrical and avionics equipment. The receptacle is located on the
left side of the airplane near the firewall. Access to the receptacle is
gained by opening the access door.
The ground service plug receptacle provides the power that will
close the external power contactor and battery contactor only if the
master switch is turned ON. This is intended as a servicing aid
when the ship's battery power is too weak to close the battery
contactor. Under normal battery conditions the master switch will
only close the battery contactor.
NOTE
If no avionics equipment is to be used or worked on, the
avionics master switch should be turned off. If maintenance
is required on the avionics equipment, it is advisable to
utilize a regulated external power source to prevent damage
to the avionics equipment by transient voltage. Do not crank
or start the engine with the avionics master switch turned
on.
NOTE
Just before connecting an external power source (generator
type or battery cart), the avionics master switch and the
master switch should be turned off.
