Hey guys, I’m having a problem with my gas gauge not working properly. When I turn on the bike my gas gauge barely lifts off the “E” and into the red zone. I checked the float and made sure it was operating smoothly (it was). I thought it might be a bad sensor, so I bought a new one and installed it after making sure it too operates smoothly. After getting the new one in and remounting the tank and reconnecting everything, I’m getting the exact same issue.

What are the chances that both float sensors could be bad? I might expect it if they both didn’t move the gauge, but their both lifting the gauge just off the “E”.

Could it be the gauge itself or is it more likely that it’s a wiring problem?

Your on the right track,,,could be the wiring,,,my guess is it's the gauge tho

I figured it out, seems the lovely people at TaoTao decided to reverse a couple of wires either from the fuel gauge or in the wiring harness.

I was reading an old post from Ally about the float sensors & ended up playing with my original float assembly. After toying with it, I connected it to the harness and discovered that it was reading backwards, (up/full was reading empty & down/empty was full).

It was a interesting fix, but I now have a working fuel gauge 😊

I have found several times the three wires connected to the back of the gauge come loose. Makes the gauge act funny.
