TESTING
RECTIFIERS
(NEGATIVE).
To
test
the
negative
case
rectifiers
in the
end
shield,
connect
the
alligator
clip
of tool
C-3829
to the
end
shield.
Touch
the
test
prod
to
the
bare
wire
of
the
rectifier
leads
at
the rectifiers
in the
end
shield.
The
meter
will
indicate
the
condition
of the
rectifier.
The
test
indications
are
the
same
for
the
negative
case
rectifiers
in
the
end
shield
as
they
are
for
the
positivecase
rectifiers
in the
heat
sink.
However
the
meter
will
read
at the
opposite
end
of
the
scale.
NOTE
If all
three
of
the
negative
rectifiers
read
low,
before
condemning
the
rectifiers,
test
for
a
grounded
stator.
A
grounded
stator
will
cause
the
negative
rectifiers
(in
the end
shield)
to
read
low.
NOTE
A common
cause
of an
open
or a
shorted
rectifier
is
a defective
capacitor
or
a battery
that
has
been
installed
