Figure 2-23. DC Electrical System (Sheet 3 of 3)
24-volt, 34-ampere/hour battery, located in the right
wing center section, is accessible through a panel on the
top of the wing. DC power is produced by two engine-
driven 28 volt, 400-ampere starter-generators. Controls
and indicators associated with the DC supply system are
located on the overhead control panel (fig. 2-12) and
consist of a single battery switch (BATT), two generator
switches (No.1 GEN and No.2 GEN), and two volt-
loadmeters.
a.
Battery Switch. A switch placarded BATT (fig.
2-1 ). is located on the overhead control
panel under the MASTER SWITCH gang bar. The
BATT switch controls DC power to the aircraft bus
system through the battery relay, and must be ON to
allow external power to enter the aircraft circuits. When
the MASTER SWITCH is placed aft, the BATT switch is
forced OFF.
NOTE
With battery or external power
removed
from
the
aircraft
electrical system, due to fault,
power cannot be restored to the
system until the BATT switch is
moved to OFF/RESET, then ON.
