New KTM 350 EXC-F Help - Low Fuel Light

I just picked up a new KTM 350 EXC-F and LOVE it!! I have never been on a *dirt* bike but just had to add one to the stable:

I got a chance to start her up and get out for some riding today, which was completely and totally awesome! This thing pulls like a tractor!

But alas, there is a tiny problem with the bike that is really frustrating me - although the issue does not keep me from riding.

The freakin' low fuel light is on constantly, even with a full tank of gas.

I have checked all the connectors, pulled them apart, inspected them, put them back together. Nothing.

I disconnected and reconnected the battery. Nothing.

I cannot find a separate connector for the fuel level sensor so I am assuming it's part of the fuel pump assembly in the tank (???).

If anyone has any ideas, I would greatly appreciate it. I know the bike is under warranty, but my closest KTM service is 150+ miles away and I want to eliminate all the "duh" things first. And because I can *see* my fuel level by looking at the tank, I am not terribly broken up by it... just an annoyance.

It wouldn't be a real fix for your issue, but you could just disconnect the light.

I believe there is a connector that you can just unplug below the light until you find out the real problem.

Maybe the sensor is disconnected inside the tank. You might need to pull out the fuel pump assembly and inspect things.

Edit: I am revising my theory... The indicator light has 12V on one side. The other side (br-rd) goes to the level sensor. The level sensor must reduce resistance to ground when low on fuel.

So... either your fuel sensor is faulty, or you have a short to ground. Check to see if the br-rd wire is shorted somewhere. If not, then you either have a short inside the tank or the sensor is faulty.
