4. If gauge shows no indication, look for an
empty fuel tank, no current to ignition terminal
because of broken or disconnected lead,
grounded wire between sender and gauge,
gauge not grounded, or sender defective.
5. Excessive pointer fluctuation may be caused
by loose wire connections or defective sender.
6. “Full” scale reading at all times may occur if
wire to sender is broken, sender is not prop-
erly grounded, of if sender is defective.
7. If gauge indicates inaccurately, sender may be
defective or there may be low voltage at
gauge terminals.
8. If the pointer fluctuates when optional head
lights are turned on, the engine is not properly
grounded.
b. Fuel Gauge Bulb Replacement
1. Disconnect negative (–) cable (2, Fig. 10.38)
from the batteries.
2. Remove four bolts (12, Fig. 10.47) which
secure the right console panel (5) and overlay
to the cab and lift and tilt panel to gain access
to the back side of the fuel gauge.
3. Tilt and lift the socket from the fuel gauge.
4. Press and turn bulb (16) counterclockwise to
release it from socket.
5. To install a new bulb, align pins on bulb with
channels in socket, push bulb into socket, turn
it clockwise to lock pins in detents, and
release it; bulb should be securely anchored in
socket.
6. Position and push socket until it seats in
gauge.
7. Lower right console panel (5) into position and
secure the panel with four bolts (12).
c. Removal of Fuel Gauge and Sender
Removal of Fuel Gauge
1. Refer to paragraph 10.8.1 for the removal of
the gauge cluster.
2. Remove the nut and wire from the right (IGN)
terminal post, Fig. 10.52.
IMPORTANT: Do not touch this wire to the left
(SEND) terminal post on the fuel gauge or the
sender capsule will be damaged.
3. Remove the nut and wire from the left (SEND)
terminal post of the fuel gauge.
4. Remove the nut and ground wires from the
center (GND) terminal post of the fuel gauge.
5. Loosen the nuts on the clip which secures the
gauge to the gauge mounting plate.
6. Lift the gauge from the gauge mounting plate.
7. Connect negative (–) cable to batteries.
Removal of Sender
1. Disconnect negative (–) cable (2, Fig. 10.38)
from the batteries.
2. Remove the nut and wire from the center
terminal on the sender.
3. Remove the screw which secures the ground
wire and sender to the fuel tank and remove
the ground wire.
4. Remove the other four screws which secure
the sender to the fuel tank.
5. Carefully remove the sender from the fuel tank
by lifting and tilting the assembly so the float

1. Position fuel gauge in gauge mounting plate
(3, Fig. 10.47).
2. Install clip and nuts which secure gauge to
gauge mounting plate.
3. Install the nut and ground wires on the center
