Aftercooler
Core
-
Inspect
The
aftercooler
is
combined
with
the
radiator,
inspect
the
aftercooler
after
the
radiator
and
aftercooler
has
been
cleaned.
Inspect
the
aftercooler
for
damaged
fins,
corrosion,
dirt,
grease,
insects,
leaves,
oil,
and
other
debris.
Bent
fins
may
be
opened
with
a
“comb”.
Inspect
these
items

Alternator
-
Inspect
Perkins
recommends
a
scheduled
inspection
of
the
alternator.
Inspect
the
alternator
for
loose
connections
and
correct
battery
charging.
Check
the
ammeter
(if
equipped)
during
engine
operation
in
order
to
ensure
correct
battery
performance
and/or
correct
performance
of
the
electrical
system.
Make
repairs,
as
required.
Check
the
alternator
and
the
battery
charger
for
correct
operation.
If
the
batteries
are
correctly
charged,
the
ammeter
reading
should
be
very
near
zero.
All
batteries
should
be
kept
charged.
The
batteries
should
be
kept
warm
because
temperature
affects
the
cranking
power.
If
the
battery
is
too
cold,
the
battery
will
not
crank
the
engine.
When
the
engine
is
not
run
for
long
periods
of
time
or
if
the
engine
is
run
for
short
periods,
the
batteries
may
not
fully
charge.
A
battery
with
a
low
charge
will
freeze
more
easily
than
a
battery
with
a
full
charge.

Battery
-
Replace
Batteries give off combustible gases which can
explode. A spark can cause the combustible
gases to ignite. This can result in severe personal
injury or death.
Ensure proper ventilation for batteries that are in
an enclosure. Follow the proper procedures in or-
der to help prevent electrical arcs and/or sparks
near batteries. Do not smoke when batteries are
serviced.
