GAUGES
If
the
gauge
reading
is
other than what
is
nonnally indicated
by
the
gauge
when
the
instrument panel
is
energized, the
first
step
is
to
check for
12
volts
DC between
the
ignition (B+)
and
tile
Negative (B-) tenninals of the
gauge.
Assuming that tilere
is
12
volts
as
required, leave the
instrument panel energized and perfonn the following
steps:
1.
Disconnect
tile
sender wire at the gauge
and
see if the
gauge
reads
zero,
which
is
the nmmal reading for tins
situation.
2.
Remove
the
wire attached to tile sender tenninal at
the
gauge
and
connect it
to
ground. See if
the
gauge reads
full
scale,
wInch
is
the nmmal reading for
tlrls
situation.
If
both of
the
above gauge tests are positive,
the
gauge
is
undoubtedly OK and the problem lies eitiler
witll
the
conductor
from
the sender
to
tile
gauge or
Witil
the
sender.
If
either of the above gauge tests are negative,
tile
gauge
is
probably defective and should be replaced.
Assuming
the
gauge
is
OK,
check tile conductor
from
the
sender
to
the
sender tenninal
at
tile
gauge
for
continuity.
Check
th&t
the
engine block
is
connected
to
the
ground.
Some starters have isolated
ground
tel'minals
and
if
tile
battery
is
colmected
to
tile starter (both plus
and
minus
tennhlals),
the
ground side
will
not
necessalily
be
connected
to
tile
block.
