5. The following resistance readings (in ohms) should be indicated, 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 fol-
lowing table 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.
6. If the readings are within the specifications listed in the preceding table, 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 13b, Page 13b-12.
7. If the readings are correct and the fuel gauge does not function correctly, leave the battery disconnected
and check the continuity of the following:
• Orange wire from the fuel level sending unit to the fuel gauge/hour meter.
• Blue wire (w25) from the fuel gauge/hour meter to the key switch.
• 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-6.
8. If the readings are correct according to the position of the float, but the reading on the fuel gauge/hour
meter is incorrect, test the fuel gauge/hour meter. See Test Procedure 25 – Fuel Gauge on
page 11b-34.
TEST PROCEDURE 25 – FUEL GAUGE
See General Warning, Section 1, Page 1-1.
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in NEUTRAL. Chock
the wheels.
2. Raise the hood.
3. Disconnect the orange wire from the fuel gauge/hour meter.
4. Set a multimeter to 20 volts DC and place the red (+) probe on the positive (+) post of the battery. Place
the black (–) probe on the negative (–) post of the battery. Record the voltage reading.
5. Set a multimeter to 20 volts DC and place the red (+) probe on the (2) terminal of the fuel gauge/hour
meter where the blue wire is connected. Place the black (–) probe on the (3) terminal of the fuel gauge/
hour meter with the black wire
(Figure 11b-28, Page 11b-35) .
6. Turn the key switch ON. The voltage reading should be the same as the battery voltage reading recorded
earlier. If not, check the continuity of the blue and black wires (Figure 11b-28, Page 11b-35) .
