My 2005 Softtail Deluxe gas gauge registers full all the time. I am thinking that the float is stuck but cann't see how to get to it to check it. When I turn the bike off the gauge needle goes down as...

This is quite common on these fuel gauges. Harley fuel gauges are not that good in my opinion. I can send you a troubleshooting guide for the gauge. Your layout may be different but the principle of operation is the same. Contact me at Don't forget to remind me of what you need.

Gauge will power up. .. stays on full, turn power off gauge goes back to empty. won't show fuel level

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 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.

2001 Harley Davidson FXSTS, I have an intermitent problem with my fuel gauge. Start with a full tank and sometimes in drops to empty or half a tank????? Thanks Mark

I have a wiring schematic of the fuel gauge on a '94 FXDWG. Your gauge may be physically a bit different but it should be wired the same. Harley's fuel gauges are known to be problematic. If you think it may help you on your bike, you'll have to contact me directly as I cannot send a file larger than 150KB here. I'll send you a scanned copy in a JPEG file (Picture file). Remind me of what you need.

Good luck

2005 FLSTN- FLSTNI Softail Deluxe: 2005 fuel gauge doesn't work...

Hi Anonymous, always check your instrument fuses first also you could have a faulty sending unit or guage, 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 ample force lift up in a rocking motion to remove 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, gauge should peg full, if not replace gauge. With a test light check for power to the sending unit and gauge, 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. For a free wiring diagram please visit the website below. Good luck and have nice day.
