A hinged
door
protects
and
gives
easv access
to the circuit breaker
panel.
Each circuit
breaker
on
the
panel
is
of
the
push to reset type
and is clearlv
marked
as
to its function
and
amperage. Circuit
prorisions
have
been
included
to handle a
full complement of
communication and
navigational
equlpment.
Standard
electrical
accessories
include a
starter. an
electric fuel
pump.
an audible
stall
warning
indicator,
fuel
gauges,
ammeter.
and
annunciator
panel*.
T|e alnunciator
panel*
includes
alternator
and
low
oil
pressure
indicator
lights.
When
the
optional
gyro
s)'stem
is installed.
the
urnunciator
partel
also
includes a low
vacuum
indicator
light.
The annunciator
panel
lights are
provided
only as a
warning
to the
pilot
that a
system may
not
be
operating
properly,
and that
he should check and
monitor the applicable system
gauge
to
de termine
wlten or if any
necessary action
is
required.
The system
also
provides
for such
optional
electrical
accessories as additional lights
and
gallges,
a
heated
pitot
head,
attd communication
and
navigational
equipment.
The master
switch
is a
split rocker
switch.
One side of
the switch is the battery side
("BAT")
and the
other
is
the
alternator
side
("ALT").
Henceforth, the
words
"masterswitch"
Irsed in this
manual
will mean
both
"BAT"
and
"ALT"
switches
and they are to
be depressed
simultaneously
to OFF
or ON as
directed.
Primary
electrical
power
is
provided
by the
14
volt
60 amp
alternator. The alternator
system
offers
many
advantages
over the
generator
system
both in operation and
maintenance.
T|e main
advantage
is full
electrical
power
output
at
lower engine
RPM. This
provides
improved
radio
and
electrical
equipment
operation
and
increased
battery
life by reducing battery load.
This
will make
cold
weather
starting
easier.
Secondary
electrical
power
is
provided
by the standard
or optiotral
battery.
Unlike
previous
generator
systems,
the
ammeter
as installed
does
not
show battery
discharge:
rather.
it indicates
the
electrical
load
on tlte
alternator in amperes.
With
all the
electrical
equipment
off and
the
master switch
on.
the ammeter
will indicate the
charging
rate
of tlte
battery.
As each
electrical
unit
is switched
ott.
the ammeter
will
indicate the total ampere
clraw of
all the
urrits
including
the
batter1,.
For exantple.
the maximum
continuous load for
1ig|t flight
with radios
on
is abont
30 amperes.
This 30
ampere
value
plus
approximately 2
amperes
for a
fully charged
battery
will
appear cotrtiltuously
under
these tlight conditions.
The
amopnt
of
current
showlr
on the
ammeter
will tell
inrmediately
if
tlte alternatcr
system is
operating
normally.
as the
amount
of current
showrr
should
equal
the total amperage drawn b1'
the
electrical
equipmetrt
which is operating.
If
1c outpgt
is
indicated
on
the ammeter
dttring
fligltt. redttce
the electrical load b1'
turlilg
off
all unnecessary
electrical
eqtripment.
C'lreck
both
the
5
ampere field breaker
and tlte
60
ampere
outpr,rt
breaker
and reset
if open.
If neithc'r
circuit
breaker
is
open. tttrn the
"AL'I"
srvitch
off
for I second
to
reset the
overvoltage
relav.
If
thc amnteter continues
to indicate
no
output.
maintain
mhimum
electncal
load and
termirtate
the
flight
as sooll
as
practical.
Maintenance
ou the
alternator
should
prove
to
be a minor
factor.
Should service
be
required.

the
local

Dealer.
