Piper PA-32RT-300T User Manual

LANCE
II SERVICE
MANUAL
NOTE
The
amount
of
current
shown
on the
ammeter
is the
load
in amperes
that
is
demanded
by the
electrical
system
from
the alternator.
As
a check,
take
for ex-
ample
a
condition
where
the battery
is demanding
10
amperes
charging
current,
then
switch
on
the landing
light.
Note
the value
in amperes
placarded
on
the
panel
for the
circuit
breaker
(10
amps)
and
multiply
this
by 80
per
cent,
you
will arrive
at a current
of 8
amperes.
This
is the
approximate
current
drawn
by
the landing
light.
Therefore,
when
the
landing
light
is
switched
on,
there
will
be an
increase
of
current
from
10 to
18 amperes
displayed
on the ammeter.
As each
unit
of
electrical
equipment
is
switched
on, the
cur-
rents
will add
up
and
the total,
including
the
battery,
will appear
on the
ammeter.

TEST
PROCEDURE.
a.
Start
engine
and set
throttle
for 2000
to 2200
RPM.
b. Switch
on
the following
loads
and observe
the
ammeter
reading increases
as
follows:
1. Anti-Collision
lights
4.4
amps
2.
Landing
light
8.0 amps
3.
Navigation
and all
instrument
panel
lights
9.0 amps
4. All passenger
reading lights
4.0 amps
5. Pitot
heat
13.0
amps
6.
Cigar lighter
8.0 amps
c. If
the ammeter
fails
to show
an increase
as indicated,
refer
to troubleshooting
chart.
d.
Additional
loads
may
be simulated
by adding
landing
lights (8.0
amps
per
light)
from the
bus bar
to the aircraft
ground.
(Refer
to Figure
1 1-1.)
e. Maximum
output
of
the alternator
should
be 60
± 5.0 amps
at 2000
to 2200
RPM.
