6-34 ELECTRICAL SYSTEM
FUEL METER INSPECTION
To test the fuel meter, perform the following tests.
Test 1
This test will determine if the fuel meter is operating.
• Remove the seat and fuel tank. (%5-2 and 4-3)
• Disconnect the fuel level gauge coupler.
• Connect a jumper wire between the B/W and Y/B lead wires
coming from the wire harness.
• Turn the ignition switch on.
• The fuel meter's needle should go past the "F" (full) line.
Test 2
This test will determine the accuracy of the fuel meter in the "E"
(empty) and "F" (full) position.
• Connect a 90–100-ohm resistor between the Y/B and B/W lead
wires.
• The fuel meter is operating correctly if the needle moves to "E"
(empty) when the ignition switch is turned on.
• Replace the 90–100-ohm resistor with a 4–10-ohm resistor.
• The fuel meter is operating correctly if the needle moves to "F"
(full) when the ignition switch is turned on.
If either test detects a malfunctioning fuel meter, replace it.
FUEL LEVEL GAUGE INSPECTION
• Remove the fuel tank. (%4-3)
• Remove the fuel level gauge. (%4-7)
• Measure the resistance at each fuel level gauge float position.
• If the resistance is incorrect, replace the fuel level gauge with a
new one.
• The relation between the position of the fuel gauge sending
unit and the resistance, as shown in the following table of next
page.
