SOURCE: Fuel Gauge reads empty all the time
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.
SOURCE: I have error codes on 2006 HD street bob. Bike will not start.
The codes are the following depending on your bike (EFI or Carb).:
P0373 CKP Sensor Intermittent Carb
P0373 CKP Sensor Intermittent EFI
P0374 CKP Sensor Not Detected Carb
P0374 CKP Sensor Synch Error EFI
U1255 Missing Message at Speedometer EFI
U1255 Serial Data Error/Missing Message EFI
U1255 Serial Data Error/Missing Message Instruments
U1255 Serial Data Error/Missing Message TSM/TSSM
this could be a number of potential things or maybe just a loose connection or ground somewhere. you are probably best to go to a shop, sorry.
SOURCE: i need to remove the fuel tank on my 2006 harley davidson
I haven't worked on a bike as new as yours but your bike is one of the Dyna series of motorcycles that Harley makes. Most Dyna's have one piece tanks instead of the twin tanks like on a Softail series bike.
To get the tank off, first remove the seat. Disconnect the fuel lines and drain the fuel from the tank. Disconnect the fuel "crossover" hose at the front of the tank. Disconnect any wires going to fuel gauges and fuel pumps in the tank. Now, take the nut off the top of the dash and remove it. There should be three bolts that hold the instrument cluster on, remove them. Unplug the connectors under the instrument cluster, usually three of those. Now, there is one bolt at the front of the tank and possibly two at the rear. Lift the tank off the frame.
Taking the tank off is not that difficult of a problem. Just watch what you're doing and don't force anything. If something won't come off, look for anonother bolt somewhere. Usually, the wiring connectors are idiot proof in that they will only connect with the correct mating plug and you can't connect them in the wrong way.
If the bike per chance has split tanks, you won't have to take the instrument panel off the frame, just the dash cover. The tanks have two bolts in the front and one bolt in the rear of each tank, one on either side of the frame.
Now, keep in mind that I told you that I haven't worked on your particular model of bike doing this particular job. But, Harley usually doesn't change much on their bikes. View the information I gave you here a "general guidelines". Use your head and you'll be using the best tool you've got. No problem.
Testimonial: "thank you. i am going to give it a shot. i layed the bike over a couple weeks ago. i need to paint the tank. "
SOURCE: Replacement of a stock fuel gauge on a '06 Harley Street Bob.
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.
It sounds like a problem with the fuel gauge sender unit in the fuel tank which has worn out and gone open circuit and needs replacing. Access to the unit is usually through a removable plate in the floor in the rear of the vehicle. Disconnect the wiring connector and any hoses and then remove the securing screws. Replacement is done by reversing procedure.
