GAUGES

the gauge reading is other than what is normally indicated

by the gauge when the instrument panel is energized, the first

step is to check for 12 volts

between the ignition (B+)

and the Negative (B-) terminals

the gauge.

Assuming that there is 12 volts as required, leave the instru-

ment panel energized (key switch on) and perform the

following steps:

Disconnect the sender wire at the gauge and see

the

gauge reads zero, which is the normal reading for this situa-

tion.

Connect the sender terminal at the gauge to ground and

sec

the gauge reads full scale, which is the normal reading

for this situation.

both

the above gauge tests are positive, the gauge is

undoubtedly

and the problem lies either with the conduc-

tor from the sender to the gauge or with the sender.

either

the above gauge tests are negative, the gauge is

probably defective and should

replaced.

Assuming the gauge is

OK, check the conductor from the

sender to the sender terminal at the gauge for continuity.

Check that the

efIgine block is connected to the ground.

Some starters have isolated ground terminals and

the bat-

tery

is connected to the starter (both plus and minus termi-

nals), the ground side

will

not necessarily be connected to the

block.
