INSPECTION
FUEL LEVEL GAUGE
Remove the fuel lever gauge. (Refer to page 4-3)
Check the resistance of each float position with a pocket
tester.
If the resistance measured is incorrect, replace the fuel
gauge assembly with a new one.
The relation between the position of the fuel gauge float
and resistance is shown in the following table.
Remove the fuel tank. (Refer to page 3-2)
Remove the fuel level gauge.
When inspecting the gauge resistance, be sure to
disconnect the battery lead wire, or a pocket tester
may be damaged.
FUEL METER
Disconnect fuel level gauge coupler. (Refer to page 4-2)
To test the fuel meter two different checks may be used. The
first, connect a jumper wire between B/W and Y/B wires coming
from the main wiring harness. With the ignition switch turned
ON, the fuel meter should indicted “F”.
The second test will check the accuracy of the meter in the full
and empty positions.
Fuel meter is normal if its pointer indicates the E(empty)
position when the specified resistance is applied to the circuit
and if its pointer indicates the F(full) position when the resistor
is changed to 4-10 ohms.If either one or both indications are
abnormal, replace the fuel meter with a new one.
When inspecting the gauge resistance, be sure to
disconnect the battery lead wire, or a pocket tester
may be damaged.
