AND
INSPECTION
a.
Scrub
each
cell
with
a
5

solution
of boric
acid
in
water,
but take

care
to
prevent
the
solution
from
entering
the
cell.
b.
Wash
each
cell
off
under
running
water
and
dry
with
an
air hose
or
clean
absorbent
towel.
c.
Inspect
each

for
defects
such
as
cracks,
holes,
or
burn
spots.
Replace
defective
cells
with
new
or rebuilt
ones.
d.
Make
sure
that
battery
hardware
is
clean
and
in
good
mechanical
condition.
Wash
the
hardware,
liners,
case,
cover,
and
other
associated
parts
in
a
warm
soapy
solution
to
remove
accumulated
dirt and
carbonate

NICKEL-CADMIUM
BATTERY
CHARGE CURRENT
DETECTOR
The
nickel-cadmium
battery
charge
current
detector
is
a
continuous
type
monitoring
system
indicating
battery
condition.
The
system
consists
of
a
shunt
in
the
negative
lead
of the
battery,
a
charge
current
detector
assembly
located
adjacent
to
the
battery
and
an
amber
caution
light
(BATTERY CHARGE)
located
on
the
instrument
panel.
The
system
senses
battery
charge
current
through
the
shunt.
The
detector
receives
power
through
a
five
ampere
circuit breaker
located
on
the
circuit breaker
panel.
Whenever
the
battery
charge
current
exceeds
three
amperes
for
six
seconds
after
starting
or
anytime
during
flight,
the
amber
caution
light
will
illuminate.
The
system
is
not
activated
by
the
discharge
current
of the
battery.
