Ground Service Receptacle

A ground service receptacle is located just aft of the cowl on the left
side of the airplane. This receptacle is installed to permit the use of an
external power source for cold weather starting and maintenance
procedures requiring reliable power for an extended period. The
external power source must be regulated to 28 VDC. The external
power control contactor is wired through the BAT 1 MASTER switch so
that the BAT 1 switch must be 'on' to apply external power.
Refer to Section 8, Ground Handling, Servicing, and Maintenance, for
use of external power and special precautions to be followed.

Convenience Outlet

A 12-volt convenience outlet is installed in the center console. The
receptacle accepts a standard cigarette-lighter plug. The outlet may be
used to power portable entertainment equipment such as CD players,
cassette players, and portable radios. Amperage draw through the
outlet must not exceed 3.5 amps. Power for the convenience outlet is
supplied through the 5-amp 12VDC OUTLET circuit breaker on the
Non-Essential Bus.
