Check for 12 volts at the orange wire on the fuel gauge. If missing check instrument fuse and associated wiring. If present do the following checks:

1. Remove gauge. Ground Y/W wire of fuel gauge sender located at bottom of gauge. Turn ignition switch ON.

a. Fuel gauge must indicate FULL. If gauge indicated FULL, gauge is functioning correctly and go to step 2.

b. If gauge did not indicate FULL, proceed to step 3.

2. Set MULTI-METER to resistance scale to measure the resistance of the sending unit. Place one probe on Y/W and the other probe on a good ground.

a. If fuel tank is full, the reading should be 40 ohms. An empty tank should have a 240 ohm resistance. A half full tank will be pproximately 97-118 ohms.

b. If a very high resistance or infinity is indicated on the meter, the sender may be "open" or not grounded. Check that sender and fuel tank are grounded by placing one probe of Multi-Meter on sender ****** and the other probe on crankcase. Meter must indicate one ohm or less. Replace sender if one ohm or less was present. If a higher resistance is present, check for poor connection on ground wire.

Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery must have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. A faulty alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Faulty main circuit breaker or ignition switch, check for loose connections and continuity.
5. Faulty system relay or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Fuel tank empty
11. Fuel tank contaminated with ethanol sludge.
12. Water or dirt in the fuel system, or clogged filter.
13. Quick disconnect check ball stuck.
14. Restricted, blocked or kinked fuel line.
15. Faulty fuel pump.
16. Faulty pressure regulator.
17. Faulty or clogged fuel injectors.
18. Lean angle switch is faulty or needs adjustment.
19. Catastrophic engine failure, perform a compression test.

Wiring must be switched around so the light is grounded when full and not when not full.

Check for good ground on the gauge and sender units as a first check.

Hi, Anonymous you could have a faulty sending unit or gauge, there could be a problem with your wiring. On models with the fuel gauge posing as a left-hand fuel cap, the gauge is a press-fit do not try to unscrew it, simply apply ample force lift up in a rocking motion to remove the gauge. Disconnect wires to the gauge and with a set of positive and negative jumpers from the battery connect the positive jumper and flash the negative, the gauge should peg full, if not replace the gauge. With a test light check for power to the sending unit, then remove the sending unit and manually operate the float arm slowly with the correct wiring hooked up to the fuel gauge and sending unit and the ignition on, the gauge should respond accordingly if not replace the float arm assembly. If your fuel gauge registers the incorrect amount of fuel in the tank you can try bending the float arm the necessary amount up or down for a more accurate reading.
