&
SYSTEMS DESCR,IPTIONS
If no
avionics
eguipment 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.
Just before connecting
an
external
power
source
(generator
tSrpe
or
battery cart), the avionics
power
switch should
be turned
off, and the
master switch turned on.
.
The
ground
service
plug
receptacle
circuit incorporates
a
polarily
reversal
protection.
Power
from the
extemel
power
source will
flow only.if
the
ground
senjrice
plug
is correctly connicted to the
airplane.
If the
plug
is
accidentally connected
backwards,
no
power'will
flow
to
the
electrical
system,
thereby
preventing
any damage to
eleetrical
equipment.
-'('
The battery
and exter:nal
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"
batt€ry. A
special
fused
circuit in
the
external
power
system
supplies
tJre needed "jumper"
across
the contacts
so that with a
"dead"
battery
and an
external
power
source applled,
turnirrg
on
the master switch
will
close the battery contactor.
