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 the Negative (B-) temrinals
ofthe
gauge.
Assuming that there is 12 volts as required, leave the
instrument panel energized and perfonn the following steps:
1.
Disconnect the sender wire at the gauge and see
if
the
gauge reads zero, which is the nonnal reading for this
situation.
2. Remove the wire attached to the sender terminal at the
sender and cOlmect it to ground.
See
if
the gauge reads
full scale, which is the nonnal reading for this situation.
If
both
of
the above gauge tests are positive, the gauge is
undoubtedly
OK
and the problem lies either with the
conductor from the sender to the gauge
or
with the sender.
If
either
of
the above gauge tests are negative, the gauge is
probably defective and should be replaced.
Assuming the gauge is
OK, check the conductor from the
sender to the sender terminal at the gauge for continuity.
Check that the engine block is connected to the ground.
Some starters have isolated ground terminals and
if
the
battery is connected to the starter (both plus and minus
terminals), the ground side will not necessarily be connected
to the block.
