Fuel Gauge reads empty all the time

I took my gas tank off my 06 HD street bob. When I put it backon and plugged everything up my gas gauge read empty. I topped it off and it still read empty. I checked the plug connections, fuses, wires everything that i could think of. Any suggestios would be awesome. Thanx.

The circuit for a fuel gauge is: battery positive through the gauge resistor to the sending unit to the fuel tank(sheet metal) to the chassis to the battery negative. If you didn't remove the sending unit the most likely problem is the fuel tank is not grounded to the frame. Scrape some paint at the rear mounting bolt where you can't see it and re-tighten the bolt. If you removed the sending unit, check the cork gasket. There should be a staple in it that is the connection to the sheet metal. No kidding.

Check t see if you are getting power to the fuse on both sides you may need to run a jump wire to make both sides get power

Fuel gauge not working


You will need to test a number of things, the fuel gauge is part of a rather simple circuit.

Battery -> gauge -> tank sensor -> chassis ground to battery

If the circuit is broken at any of the steps, your gauge will read "empty". If the tank sensor is bad, it could read empty, or if the float in the tank has sunk, it will read empty.

I start at the gauge with a "test light" that glows when it sees battery voltage. Get a light at the connection to the gauge? Good. find the sensor connection, usually on top of the tank, accessible in the trunk. Probe with test light. Light on? Good. Connect wire to ground, gauge should read "full". If all that is as I said, then the tank sensor is bad. If you don't read battery at any step, you know where the problem is.

My gas gage reads empty but stays lit up on 2005flht


The fuel gauge sender is mounted internally in the fuel tank. There is a three pin connector that will have a Yellow/White wire in it (the middle wire) under the center console. This is the sender wire. Connect an ohm meter between this wire and the black wire and check for the following readings:
If fuel tank is full, the reading should be 7-14 ohms. An empty tank should have a 74-95 ohm resistance. A half full tank will be approximately 30-38 ohms.
If you ground this wire that comes from the harness, the fuel gauge should read full. If not, then fault may be in wiring or the fuel gauge itself.
Remove the front fairing to gain access to the gauge. You should have 12 volts across the orange/white and black wires. If not, check accessory fuse. If 12 volts present ground the yellow/white wire at the gauge. Gauge should read full scale. If not, gauge faulty. If gauge reads full scale, check wiring from gauge to three pin plug under tank console.

Digital gas gauge reading incorrectly and inverted


sounds like a faulty sender unit or your just realy low on fuel before you spend any money on repairs try filling the tank up with fuel as if its been low for a long time the sender unit in the tank may be sticking the fuel will lube it and may start working again

Why is gas gauge not working correctly since fuelpump was replaced.


Is this a flex fuel vehicle. If so, call the dealership and ask the parts dept. if there is a gauge module (perhaps behind the instrument cluster). This may be the culprit and needs to be replaced.

06 FLHX I Street Glide Fuel Gauge issue.\r\nI guess I've been one of the lucky guys whose fuel gauge worked really well & quite accurate since I bought the bike in 06. Now it has been reading...


Contact me directly and I'll send you some information on the principle of operation and troubleshooting the gauge. It's out of an older manual but the principle is the same and I think the readings are the same. The float is on the sending unit and usually if the float goes bad, it sinks and the gauge should read empty all the time. But, since the original did the same thing, it shouldn't be that the arm got bent either. wd4ity@bellsouth.net Make sure you remind me of what you need.

Have a 2001 gmc jimmy...drove home gas gauge read 1/4 tank..next day cranked over but wont start..gas gauge reads empty...put $10.00 from spare gas can..cranked over but no start ..gas gauge still reads...


chevy and gmc trucks have an on going problem with this,turn the key on,and get a rubber mallot or a hammer and hit the bottom of the fuel tank a couple of times,this will unstick something in the fuel pump/sending unit.

Gas gauge shows empty after filling gas tank. Eventually the gas gauge will register the proper level.


The gauge circuit is shunted on most cars, this is wierd, but needed to stabilize the readings... Your description sounds like normal function. Drivers would complain if the qauge were to be instant, going around corners, starting, stopping, all move fuel, and the gauge would indicate this, cauing driver alarm...Been this way for ever, although yours sounds like it is on the far side of the scale...if it reads correctly after a while, you could replace everything and you would have the same performance.

no need to remove tank, Remove terminal pins from connector under left side of tank then pull gauge and wires out. Install new gauge, replace terminal pins in their propper place in the connector,plug it in and varify the repair.
