    Yesterday. after a bouncy uphill ride, I noticed that the fuel light was flashing on and off with 2/3 of a tank. Eventually it was more on that off and now is always on. I have filled the tank since and the light stays on. Some observations I have made are...

    1.) when stopped at a traffic light the fuel light will almost always go out only to come back on once underway.
    2.) on the kickstand when I turn the bars all the way to the left the light goes out. bring the bars back to center the light comes on. Turning bars to the right does nothing. Light stays on.

    I was thinking maybe my bouncy ride knocked something loose inside the tank. I expect I will have to pull the fuel pump out for a look-see as not much can be done through the fill hole. I was wondering if anyone has had a similar issue with their fuel light? maybe it is an electrical thing? I will check the wiring before pulling the fuel pump.

    Bike is a 2011 SM 620 with about 13000km.

    Any insight would be appreciated. Thank you.

    Well it looks like I figured it out.

    Turns out there was a broken wire in the main harness right up parallel with the left radiator. This brown wire in a rainbow of wires snaked into it's own special cover inside the loom but because it was broken came out when gently pulled. Cutting back the special cover 3cm revealed that the brown wire connects to a solid core bare wire using some sort of side by side crimp. The brown wire had broken off here. One but connector, two pieces of heat shrink tubing and some electrical tape, plus hours of time and it is all back together. The bike runs and all the lights work! I still have to wait and see if the fuel light will come on at the proper time when the level gets low. That trouble shooting I look forward too because it is such a nice day out for a ride.

    I hope this information might help somebody else in the future if they unfortunately need it.

    My low fuel light is always on since I bought the bike... Never figured it out. Of course mine is an entirely different model ( TE 310) but maybe I'll poke around the main harness. I've already checked all connectors, etc. ...all the obvious.... NADA

    Your problem is likely the resistor soldered into the wire leading from the sensor in the petcock has broken loose. You will find it in the loom on the left side of the bike heading towards the front of the bike. I should be right about the point the loom passes the radiator. Mine does the same thing. I just disconnected the connector from the petcock under the tank and the light goes out. I just use the odometer as my fuel gauge.

    My TE610 I bought used, and it never had the sensor connected...

    I've filled up with about 11L before, without the light on, and other times I've had it come on fueled up with only 10L of fuel...

    I know for sure, if I make it to 200km, I better fill up.

    My 310, a 13, was a failing petcock sensor. $45 and 2 screws to replace.

    How did you test it to figure it out?

    Pull connector and check continuity. You should get continuity if float is down but not up/with a full tank/float up.

    Mike, let me ask you.. I've yet to get an idea of the range of my TE310.. at what point (mileage) do you feel you need to re-fill your 310?

    So your saying that if I have a full tank, and then place a VOM across the wires in the connector and they show a short, then replace the "petcock sensor", correct? You wouldn't happen to have part number would you!? :)

    I'm running the TXC ECU and injector along with a pipe. I'm looking for fuel at 80 miles. Looking real hard at 100.

    So, I have a short with fuel in the tank (going across the two pins from the petcock) .. also if I pull the plug apart while it is running the fuel light STILL stays on? .. *I'm confused:confused:
