2. Disconnect the orange wire from the center post of the fuel level sending unit.
3. With a multimeter set to 2 kΩ (ohms), place the red (+) probe of the multimeter on the center post of the
sending unit. Place the black (–) probe on the ground connection of the sending unit (Figure 11b-56,
Page 11b-45).
4. The following resistance readings (in ohms) should be obtained depending on the position of the float
inside the fuel tank. The resistance reading will vary according to the exact position of the float. The chart
below may be used as a guideline to determine if the fuel level sending unit is operating correctly. Make
sure the float is at the surface of the fuel in the tank.
FLOAT POSITION
Lower position (tank empty)
Center position (tank half full)
Upper position (tank full)
5. If the readings are within the specifications listed above, the fuel level sending unit is working properly.
If the readings are incorrect, the fuel level sending unit has failed and the fuel tank must be replaced. See
Fuel Tank Removal, Section 14, Page 14-28.
6. If the readings are correct and the fuel gauge does not function correctly, check the continuity of the
orange wire from the fuel level sending unit to the fuel gauge/hour meter. Leave the battery disconnected
while checking continuity. Also check the continuity of the blue wire from the fuel gauge/hour meter to the
key switch, and the black ground wires at the fuel level sending unit and at the fuel gauge/hour meter. See
Fuel Gauge/Hour Meter Removal, Section 12b, Page 12b-24.
7. If the readings are correct according to the position of the float, but give an incorrect reading on the fuel
gauge/hour meter, test the fuel gauge/hour meter. See Test Procedure 26 – Fuel Gauge on
page 11b-46.
