Power / SetUp
This
condition
can
produce
an
open
circuit
Voltmeter
indication
of
satisfactory
Voltage,
because
the
resistance
of
degraded
continuity
is
difficult
to
detect
in
an
open
circuit.
Degraded
circuit/wire/
ground
connections
can
often
be
detected
by
detecting
the
difference
in
Voltage
at
the
load
when
OFF
and
when
ON.
Resistance
of
degraded
connections
will
prevent
full
V
oltage
when
the
circuit
load
(Indicator)
is
ON.
If
possible,
turn
the
Indicator
ON
and
OFF
while
monitoring
the
primary
power
Voltage.
Be
alert
for
a
significant
drop
in
Voltage
when
the
system
is
turned
ON.
For
example
if
the
open
circuit
Voltage
is
11.5
and
drops
to
10
V
or
9.5
V
etc.
when
the
indicator
is
turned
ON,
this
change
is
an
indication
that
the
system
battery
may
need
to
be
charged
or
that
continuity
of
the
conductors
and
connections
between
the
battery
to
the
indicator
may
have
been
degraded
by
corrosion
or
loosening,
etc.
4. During
testing,
move
the
Indicator
in
its
bracket
while
monitoring
the
Primary
Voltage.
The Indicator should not turn OFF.
Watch for any disturbance in the display (if the Power problem is
intermittent).
Voltage
readings
and
Indicator
Display
should
show
no
aberrations,
flicker,
etc.
If
movement
of
the
Indicator
affects
the
Primary
Power,
test
each
power
connection.
If
Primary
Power
is
delivered
via
a
plug
at
the
side
of
the
Indicator,
check
that
the
plug
is
the
correct
size
to
fit
the
barrel
and
also
the
center
pin.
Install
the
correct
size
plug,
if
this
connection
is
physically
sloppy
or
electrically
intermittent.
If
power
is
hard-wired
to
the
internal
Euro
connections
of
the
rear
panel,
remove
the
rear
cover
and
check
the
internal
power
wiring
for
connection
and
continuity.
The
Euro
connections
are
spring-loaded
with
an
internal
knife-edge.
The
insulation
of
the
wires
inserted
in
these
terminals
should
have
the
insulation
trimmed
back
to
expose
a
t least
3/8
inch
or
10mm
of
bare
wire.
The
bare
wire
strands
would
be
twisted
so
that
there
are
no
"flying"
strands
and
so
that
the
twisted
wire
may
be
inserted
smoothly
into
the
Euro
c
onnector
block
connection.
Depress
the
loading
tab,
insert
the
twisted
wire,
release
the
loading
tab.
Now,
give
the
wire
a
gentle
tug
to
seat
the
internal
clamp
and
assure
that
the
wire
does
not
slip
loose.
5. Internal dry cell batteries may be discharged to below minimum Voltage required to operate
and will cause
the Indicator to turn Off
.
