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 meter is operating but will
not indicate the meters accuracy throughout the range. To
perform this test, remove the seat and right frame cover and
disconnect the B/W and Y
IB
lead wires of the fuel gauge
sending unit. Connect a jumper wire between B/W and Y
IB
wires coming from the main wiring harness. With the ignition
switch turned 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 11 O-ohm resistor between the
Y
IB
lead wire of the fuel gauge and the ground lead wire. 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 3 ohms. If either one or both indications are
abnormal, replace the fuel meter with a new one.
