the
"Y"
connection
as
is necessary
where
the test
lamp
method
is
used.
Due
to
the
short
leads
at the
"Y"
connection
it
is
quite
difficult
to separate
and
reconnect
them
properly.
This
tool
C-3829
will
save
much
time
and is
ac-
curate.
Insulate
alternator
from
metal
bench
and
plug
tester
tool
C-3829
into
a
110
volt
supply.
Connect
the
alligator
clip
of
tool
C-3829
to the
alternator
"BAT"
terminal
and
touch
the
bare
metal
of
each
of
the positive
case
rectifier
lead
wires
in
the
heat
sink
at the
rectifiers.
The
meter
reading
for
each
of
the
rectifiers
should
be the
same.
Always
contact
the
connection
nearest
the
rectifiers.
Do not
break
the
sealing
on the
rectifier
lead
wire
or
on the
top
of
the
rectifiers.
The sealing
material
is used
for
corrosion
protection.
The
reading
on
the
meter
will
indicate
1.7 or
over
for
good
rectifiers.
Where
two
of
the
rectifiers
are
good
and one
is
shorted,
the
reading
taken
at
the
good
rectifiers
will
show
low.
The
reading
at the
shorted
rectifier
will
be zero.
Cut
the
lead
at the
bad
rectifier
and
the
reading
at the
two
good
rectifiers
will
come
up
to
normal.
Where
one
of the
rectifiers
is open,
it will
read
low
(1 amp
or
less)
the
two
good
rectifiers
will
show
normal.
