MANUAL
9-10. FUEL QUANTITY SENDER
UNIT.
NOTE
Inboard
and outboard
fuel tanks
in each
wing are
interconnected
and have
a total
capacity
of 49
gallons.
Fuel
quantity
sender units mounted
in each fuel tank transmit
electrically
the
cumulative quantity
of
fuel in each
set of
tanks, to fuel
quantity
gauges mounted
in the
instrument
panel.
9-11.
FUEL QUANTITY
SENDER/GAUGE
CHECK (INSTALLED).
Fuel quantity
sender
units and
fuel quantity gauges
can be checked
while mounted in the
airplane by using
the
following
procedure:
a.
Put the fuel
selector levers
in the
"OFF" position.
Completely
drain fuel
tanks that
relate
to the
fuel quantity
senders
and gauge
to be
checked.
(Refer to
Draining
Fuel System,
Section II.)
b.
Level airplane
laterally (refer
to Leveling,
Section
II) and position
the aircraft
with a
1 degree
nose
up attitude.
NOTE
The
electrical system
should
supply 12 to
14-volts to the
gauge.
c.
With the
master switch
in the "OFF"
position,
the gauge
needle should
be centered
on the
white dot to the left of the "0" radial
mark, with a maximum deviation
of 1/4
needle
width.
If not within
this
tolerance,
the gauge
should be
replaced.
d.
With the
master
switch
in the "ON"
position
and
no fuel in
the tanks,
the gauge
needle should
be centered
on the
white dot
to the left of
the "0" radial
mark with
a
maximum
deviation of
1/4 needle
width. If not
within this
tolerance, the
gauge should
be
replaced.
e. Place
2 gallons
of fuel
in the wing
fuel tank
that relates
to the
gauge
and sender
unit
being
checked.
f. With
12 to 14-volts
DC supplied
to the electrical
system
and the master
switch
in the
"ON"
position, the needle
should be centered
on the "0" radial
mark; plus 0,
minus 1
needle
width.
g.
If the needle
does not read
within the
above tolerance,
remove
the sender
wire from
the rear of
the gauge and
check the
resistance to
ground through
the sender
circuit. If
the
resistance
is not within 5 ±
1 ohms, replace the
inboard sender. Then,
recheck as specified
above.
h.
Add fuel
to the
tanks in
accordance
with
the information
given
in Table
IX-I until
tanks are
full. Observe
the
gauge reading
at each
10 gallon
increment
i. With
the tanks
full and
master
switch
"ON," the
needle
should be
centered
on the
"F" radial mark within + 1 needle
width. If not within this tolerance, adjust
the electrical
adjustment
(refer to Figure
9-3) just
sufficiently
to bring it
within tolerance;
do not
center
the needle.
