tr
THE
PIPER CHEROKEE
sorles.
Circult
provlslons
are
made
to
handle
optlonal
commun-
lcatlons
and
navlgational equipment.
In
conventlonal
generator
systems, the
ammeter
indicates
battery discharge.
In
the
Piper
FullTime Powerelectrlcal
sys-
tem, the
ammeter
displays
the
load
in
amperes
placed
on the
system
at
any given
time.
Wtth
all
electricalequlpment
except
the master switch
in
the
"OFF" positionr
the
ammeter
will
in-
dicate
the amount
ofcharging
current
demandedby the
battery.
This
amount
will
vary
and
depends
on the
percentage
of full
clørge
on
the
battery
at
tåe
time.
When the
banery
becomes
charged,
the
current
dlsplaeed
on
the
ammeter
will
reduce to
a mlnimum value of
about
two
amperes.
As each
unit
of
elec-
trical
equlpment
ls
swltched
on
the amount of
current ir
draws
will
be
shown
on
the
ammeter.
The
maximum
cqltlnuous
load
for nlght flight with all
equipment
on
is
approximately thirty
amperes, Thts
thlrty
ampere
s
plus approximately
two
amperes
for
the
futly
charged
batterywill
appear
conriouously under
these
flight
condittoos.
Because
of
the
mechanical
simpliclty
of
the
alternator,
matnteoance
should prove
to
be
a
minor factor as
compared
to
prevlous systems.
Should
service
be
requlred,
contact
your
local
Piper dealer.
HEATING
AND
VENTII.ATING
SYSTEM
Heat
for
the
cabln
lnterlor
and the
defroster
system
is pro-
vided
by
a
heater muff
attached
to
the
exbaust system.
Con-
trols fof
these
systems are locatedon
the
lower
right
hand
side
of
the instrument
panel.
A
third confrol in this
area
regulates
a
large fresh
air
vent
located
on
the
left
hand
stde of the cabin
near
the
pllot's feet.
In
addition,
two
side
vents
are provided
one
at
each seat
location. Th"y
may
be
tndependentlyregulated
as
desired by the
seat
occupant.
