the termInal end of
the saId

to
the
body
of the car
If the IndIcator of the
dash UnIt
SWIngs
actIvely
between E and

the
wlrmg
between the dash UnIt
and the saId termInal
end IS In
good
condItIon WIth
the de

eXIstIng
either In

poor ground
of
thIS
UnIt
In the
test mentIOned In the

sectIon If the IndIcator
does not
SWIng
but
It
moves moves
to
E when
the dash UnIt
end
of the
wlnng
from the
tank UnIt
IS
grounded
the
wlnng
between the dash UnIt and tank UnIt
IS defectIve
Therefore
reWIrIng
or
repalnng
IS
requIred
If when IndIcator
flals to

but
sparkIng
IS observed when the
WIrIng
connectIng
the
battery
wIth the termInal on the dash
UnIt IS dIsconnected
at
the
dash
UnIt
end
and
grounded
It
proves
the
wirIng
IS
satIsfactory
and the trouble
IS In the dash
UnIt
Itself
If
sparkIng
does
not occur the
WIrIng
wmch IS
thus
IndIcated
to
be
out
of
order should
be
repaIred
or
replaced
Incorrect
readIngs
of the IndIcator
probably
means
that the
heIght
of the float
of the
tank UnIt IS m error
In thIS case
adjust
the
heIght
of the float
by
bendIng
the rod
Troubles with the
UnIt
are dIffIcult to
repaIr
so It
should be
replaced by
a
new
