GROUND SERVICE
PLUG RECEPTACLE
SECTION 1
GENERAL
The ground service plug receptacle permits the use of an external
power source for cold weather starting and lengthy maintenance work on
the electrical and electronic equipment. The receptacle is located behind a
door on the left side of the fuselage near the aft edge of the cowling.
The battery and external power circuits have been designed to com-
pletely eliminate the need to "jumper" across the battery contactor to close
it for charging a completely "dead" battery. A special fused circuit in the
external power system supplies the needed "jumper" across the contacts
so that with a "dead" battery and an external power source applied, turning
the master switch ON will close the battery contactor.
SECTION 2
LIMITATIONS
The following information must be presented in the form of a placard
located on the inside of the ground service plug access door:
