Poor soldering
Check
9057
(Plate),
various
resisters,
and
lead
wires
for
poor
soldering
or
short-circuit,
and
make
necessary
repairsor
adjustments.
Position of resisters
Check
the
following
points
and
make
necessary
repairs
or
adjustments:
o
Is
the
resister
soldered
onto
the
printed
board
as
tightly
as
possible?
o Isn't
the register
in contact
with
9108?
o
Isthe
printed
board
fixed
closer
toward
the
surface
of
the
rails
on
the camera body?

CdS wire disconnected
In
case
when
the
value
indicated
is
extremely
in
minus
either
in
high
or
low
luminosity,
check
for
disconnection
of
the
CdS
wire
as
follows:
o
Conductivity
of
the
red
CdS
lead
wire
(for
both
high
and
low
luminosities)
,
o the black CdS lead wire (for high luminosity), and
o
the
green
CdS
lead
wire
(for
low
luminosity).
Disconnection
of
wire
in
the
mechanical
part
(no
needle
swing)
Remove
the
lead
wire
by
unsoldering
and
check
the
conductivity
of
the
mechanical part.
If
disconnection
is
found,
replace
the
whole
meter
assembly.
