INSTALLA
TION
a.
Position
the
detector
assembly
on
the
base and install the
two
screws
and
washers.
b.
Connect the
electrical
connector to
the
detector
assembly.
c.
Install
the
access
cover.
d.
Perform
a
functional
check
to
determine
the
system
is
working
properly.
FUNCTIONAL
CHECK
NOTE:
Satisfactory
load
change
as
used
herein,
is
defined
as
deflection
of the
loadmeter
needle
equal
to
or
less
than
a
0.025
load
change
(approximately
3
amps)
for
airplane
with
a
13.5
amp-hour
battery.
A load
change
I
of 0.025
or
0.050
is
barely perceptible.
The
system
may
be
checked
in
the
airplane
with
either
engine running.
After
the
engine
is
started,
turn the
applicable
generator
ON.
After
a
time
delay
of
approximately
6
seconds
(provided
the
battery
is
sufficiently
discharged
and
will
accept
a
charge),
the
amber caution
light
(BATTERY
CHARGE)
located
on
the
instrument
panel
should
illuminate.
The
light
should
remain
illuminated until the
battery
is
recharged.
Under
normal
circumstances,
the
battery
should
be
recharged
and
the
fight
should
go
out
within
5
minutes.
However,
if the
battery
has had
unusually
low
or
high
drain,
the
recharge
time
could
be
considerably
shorter
or
longer.
When
the
light
does
go
out,
turn
the
battery
switch
off while
observing
the
affected
loadmeter;
the
loadmeter
should indicate
a
satisfactory
load
change.
Listed
below
are
possible
situations that
could
be
experienced
and
corresponding
action that
is
recommended:
a.
Light
does
not
illuminate
If the
bulb
is
operational
but the
light
does
not
come on
within
approximately
6
seconds
after
the
operating
generator
is
turned
ON,
it
is
possible
that
the
battery
is
not
sufficiently discharged
to
accept
a
charge.
This
can
be
determined
by
turning
the
battery
OFF while
observing
the
loadmeter
needle
deflection.
A
satisfactory
load
change
indicates
the
battery
is
charged
and
the
light
should not
be
on.
An
unsatisfactory
load
change
indicates the
light
should
be
on
and
that
there is
a
malfunction
in
the
detector
system.
Repair
or
replace
the defective
parts
and
repeat
the
functional
check.
If
the
battery
was
not
discharged
enough
to
accept
a
charge,
turn
the
generator
off
and
partially
discharge
the
battery
by
operating
electrical
equipment.
Repeat
the
functional check.
b.
Light
stays
on
Check
the
following
possibilities:
1.
Battery
is
partially
discharged
and
is
being
charged.
If
the
right
stays
on
after
charging
for
approximately
5
minutes,
careful
attention
should
be
given
the
airplane
loadmeter.
With
a
constant
load
on
the
airplane
electrical
system,
continue
to
charge
the
battery.
The
loadmeter
should indicate
a
constantly
decreasing
charge
current
until the
battery
is
charged.
When
the
loadmeter
appears
to stabilize
(see
NOTE
in condition
2
below),
turn
the
battery
off
while
observing
the loadmeter
for
load
change.
If
the
load
change
is
satisfactory
and
the
light
has
gone
out,
the
battery
is
charged
and
the
system
is
operating
properly.
2.
Battery
is
charged
and
is
being
excessively
overcharged.
If
the
loadmeter stabilizes
and indicates
an
unsatisfactory
load
change
when the
battery
is
turned
off,
the
battery
is
overcharging excessively
and
the
light
should
not
have
gone
out.
Check
the
battery
and
charging
circuit
for condition
and
proper
operation.
NOTE: As
the
battery approaches
full
charge,
the
charge
current
may
decrease
slowly
enough
that
the
loadmeter
would
appear
to
stabilize before the
charge
current
has
decreased
enough
for
the
light
to
go
out.
