while performing this test procedure.
1. Disconnect the battery cables as instructed. See WARNING “To avoid unintentionally starting...” in
General Warnings, Section 1, Page 1-1.
2. Disconnect the orange wire from the center post of the fuel level sending unit.
3. With a multimeter set to 2 k 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 11-35,
Page 11-34) .
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.
