what is 
nOlmaJ.Jy 
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-) tenninals of the 
gauge. 
• 
Assuming 
that tilere is 
12 
volts 
as 
required, leave the 
instmment panel energized and perfonn 
the 
following 
steps: 
1. 
Discounect 
the sender 
wire 
at the gauge 
and 
see 
if 
the 
gauge 
reads 
zero, 
which 
is 
the 
nOlmal 
reading 
for 
tlris 
situation. 
2. 
Remove 
the wire 
attached 
to 
the sender tenninal at 
tlle 
gauge 
and 
connect 
it 
to 
ground. 
See 
if 
the 
gauge 
reads 
full 
scale, 
which is the nonn.l reading for 
11ris 
situation. 
If 
both of 
the 
above 
gauge 
tests 
are 
positive, 
the 
gauge 
is 
undoubtedly 
OK 
and the 
problem 
lies 
eitller 
with 
tlle 
conductor 
from 
the sender 
to 
tl,e 
gauge or 
with 
the 
sender. 
If 
either of 
the 
above 
gauge 
tests 
are 
negative, 
tlle 
gauge 
is 
probably 
defective 
and 
should 
be replaced.  . 
Assuming 
the 
gauge 
is 
QK, check 
tlle 
conductor 
from 
the 
sender 
to 
tlle 
sender tenninal 
at 
the 
gauge for 
continuity. 
Check that 
the 
engine block 
is 
connected 
to 
the 
ground. 
Some 
starters 
have isolated 
ground 
!enninals 
and 
if 
tlle 
battery 
is 
cOimected 
to 
tlle 
starter 
(both 
plus 
aud 
minus 
terminals), 
the 
ground 
side 
will 
not necessarily 
be 
connected 
to 
11le 
block.
