PLUG RECEPTACLE
SECTION 1
GENERAL
The ground service plug receptacle permits 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
behind a door on the left side of the fuselage aft of the baggage compart­
ment door.
NOTE
If no avionics equipment is to be used or worked on, the
avionics power switch should be turned off.
If
maintenance
is required on the avionics equipment, it is advisable to
utilize a battery cart external power source to prevent
damage to the avionics equipment by transient voltage. Do
not crank or start the engine with the avionics power
switch turned on.
A special fused circuit is included with the ground service plug
receptacle which will close the battery contactor when external power is
applied with the master switch turned on. This circuit is intended as a
servicing aid when battery power is too low to close the contactor. and
should not be used to avoid performing proper maintenance proced ures on
a low battery.
NOTE
Use of the ground service plug receptacle for starting an
airplane with a "dead" battery or charging a "dead"
battery in the airplane is not recommended. The battery
should be removed from the airplane and serviced in
accordance with Service Manual procedures. Failure to
observe this precaution could result in loss of electrical
power during flight.
