FUEL LEVEL METER/GAUGE
FUEL METER INSPECTION
To test the Fuel Meter two different checks may be used. The first,and simplest test will tell if the
mete is operating but will not indicate the meters accuracy throughout the range.To perform the
test,lift the seat and remove the right frame cover,then disconnect the B/W and Y/B lead connector
of the fuel gauge sending unit.Connect a jumper wire between B/M and Y/B wiers coming from the
main wiring harness.With the ignition switch tuined ON,the fuel meter should indicate“F”.
The second test will check the accuracy of the meter in
the full and empty positions.Connect a 90-ohm resistor
between the Y/B and B/W lead wires.The fuel meter is normal
if its pointer indicates the E(empty) position when the
specified voltage is applied to the circuit and if its
pointer indicates the F(full) position when the resistor is
changed to 10 ohms.If either one or both indications are
abnormal,replace the fuel meter with a new one.
FUEL GUAGE SENDING UNIT INSPECTION
Disconnect the lead wires coming out of the fuel gauge and
check resistance of eadn podition.
If the resistance measured is incorrect, erplace the fuel gaue
assembly with a new one.
The relation between the position of the fuel guage float and
resistance is shown in the following table.
