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.
