9.15.14 Fuel Level Indicator and Fuel Level
Sender
The fuel level indicator (Fig. 9 -95, 1) can be found on the
operator’s instrument cluster.
Figure 9-95 Fuel Level Indicator
The fuel level indicator (Fig. 9 -95, 1) works in conjunction
with the fuel level sender (Fig. 9 -96, 1). The submerged,
coil-type fuel sender is secured to the fuel tank (2) and is
connected to the operator’s instrument cluster via the
engine wiring harness, bulkhead connector and cab
wiring harness.
Figure 9-96 Fuel Level Sender
The operator’s instrument cluster fuel level indicator
(Fig. 9-95, 1) shows the level of fuel remaining in the fuel
tank. The fuel level sender wiring harness connector can
be accessed from the top of the fuel tank.
The fuel level sender (Fig. 9-96, 1) consists of a resis-
tance, float-type fuel level sender mounted in the top of
the fuel tank (2) and the wiring (3) connecting it with the
fuel indicators in the operator’s instrument cluster.
The resistance of the fuel sender is 31 ohms for a full tank
of fuel, 101 ohms for 1/2 tank and 255 ohms for an empty
tank. The fuel level indicator gauge in the operator’s
instrument cluster receives a signal from the fuel level
float sender corresponding to the remaining amount of
fuel in the tank. Examine the fuel level sender circuit in
Section 9.9.7, “Fuel Level Indicator Troubleshooting.”
a. Fuel Level Indicator Testing
1. Remove fuel tank cover.
2. The fuel level sender wiring harness leads
(Fig. 9-96, 3) can be accessed from the top of the
fuel tank. Disconnect the fuel level sender wiring
harness leads. With the help of an assistant, touch
both harness leads together.
3. From the operator’s cab, have the assistant turn the
ignition key switch to the RUN position (Fig. 9 -97).
DO NOT start the engine. Observe the fuel level
indicator needle on the operator’s instrument cluster.
The reading must be at the FULL mark after the
engine start-up bulb test is completed.
Figure 9-97 Ignition Key Switch RUN Position
4. Turn the ignition key switch to the OFF (Fig. 9-97)
position. The needle should return to the EMPTY
position.
