When the ignition switch is ON the fuel gauge is connected to 12 VDC, current flows through the gauge and the variable resistor in the fuel gauge sending unit to ground. The sending unit float controls the amount of resistance in the variable resistor. Malfunctioning fuel gauges may be the result of a fuel gauge sender or a fuel gauge not being properly grounded OR there may be a defect in the fuel gauge sender or in the fuel gauge itself OR there may be an open circuit caused by a loose or disconnected connection or a broken wire between the ignition switch to the fuel gauge.



A suspect fuel gauge system can be tested by FIRST removing the gauge and grounding the Y/W wire of the fuel gauge sender located at the bottom of the gauge, turning the ignition switch ON at which point the fuel gauge must indicate FULL. And if it does so then the fuel gauge is functioning correctly.And if it does not read FULL then get a multimeter set to the RX1 scale and measure the resistance of the sending unit by placing one of the meter probes on the Y/W wire and the other probe on a good ground. THEN for Softail if the fuel tank is full, the reading should be 27-40 ohms. an empty tank should have a 240-264 ohm resistance and a half full tank will be approximately 97-118 ohms. FOR ALL MODELS if there is a very highmeter resistance or infinity reading the sender may be "open" or not grounded. In this case check to see if the sender and fuel tank are grounded by placing one of the ohmmeter probes on the flange of the sender and the other probe on crankcase and if the ground is good the meter must indicate one ohm or less and if the reading is one ohm or less the sender is defective and requires replacement and if a higher resistance reading is obtained you will need to check for a poor ground wire. THENyou can check the voltage to the O/W (+) wire and the BK (-) wire of the fuel gauge connector if the gauge did not indicate FULL and the correct reading will depend on the source voltage and the level of fuel in the tank or the position of the sender float arm on the variable resistor etc. If there is NO battery voltage present there may be a broken, highly corroded or disconnected power wire. If you cannot find a problem using the above testing replace the gauge itself.

SOURCE: gauge will power up. .. stays on full, turn power

If you'll contact me directly, I'll send you some information on the fuel gauge. The info is or a 1994 FXDWG but the gauge works the same way on all Harley bikes. They may be laid out a bit different but the principle is the same. Contact me at wd4ity@bellsouth.net and I'll send you the information. This forum only allows files no bigger than 150Kb and they're bigger than that. Don't forget to remind me of what you want, I get lots of request for info.

Fuel gauge stays on full mark when empty, but the low fuel indicator light comes on. working the fuel sending unit by hand, I raise up the float and the low fuel light goe off


Fuel gauge could be bad .Depending on make , model and year vehicle ! The instrument cluster would need to be pull from the vehicle and sent out to be fixed or buy a new one .

Guages not working,


If all voltages checked ok,then most probably its faulty instrument cluster board on which gauges are connected.Yes if cluster circuit board looks ok,then also it can be faulty.Somewhere there is minute short or burn on board then such prolem arises.
Also check the fuse box.One under hood and other under dash.Inspect each and every fuse and see if all are fine or not.

My fuel gauge floats from full to empty when I stop at a light! And its stays on empty until I drive for about five minute why is that? I can't get an accurate fuel reading!!


I have the same vehicle and my car actually was full of gas, registered empty & left me on the side of the road..It was the sensor in the fuel line that had to be replaced.

All your gauges are working. The gas gauge Is also working. When you fill it, you will fill over the limit the fuel level switch will go by a couple of gallons. So the gauge will not drop for a few miles. until you use up the excess fuel

Fuel guage stays on empty and low fuel light stays on,no other problems


You might have a leak in the float in the fuel tank sender unit (the float should sit on top of the fuel and feedback info to the gauge - the fuel gauge staying on empty might mean that the float is either leaking or it is stuck).

1989 Saab 900 low level fuel light


You don;t say whether the fuel gauge is reading accurately, or whether it's always on empty. If the gauge is always showing empty, it's most likely a problem with the sending unit in the fuel tank. Check the resistance across the two terminals of the sending unit.

On a C900, the fuel sender level unit is separate from the fuel pump and located on the right side top of the tank, accessible by removing the trunk floor lift up panel (the pump is located on the left side top of the tank.
Possible problems are: electrical line off or broken, float not working (it's fairly delicate); or gauge not working.

Test the resistance of the sending unit with the lines disconnected, the resistance should be 2.6 to 3.8 ohms full tank, 63.3 to 67.5 ohms empty tank; and test for voltage across the top of the sender unit, if no voltage, that's likely the problem!

If the gauge is otherwise reading accurately (showing 'full' for a full tank, etc) then the problem is likely a gauge malfunction and can be simply replaced.

Good luck!
