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
wirebetween 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.
FLOAT POSITION RESISTANCE
F（FULL） APPROX.33
1/2 APPROX.200
E（EMPTY） APPROX.566
