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 operat-
ing but will not indicate the meters accuracy throughout
the range. To perform this 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/W and Y/B 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 90 Ϊ 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 Ϊ .
