Fuel Light coming on with full tank

[rrod1393]

So just got my GL1200 on the road after it has been sitting for over five years outside from the PO. I did a complete service on the bike and its up and running well. I am enjoying it. The issues I was having while I took it for its test ride was the fuel light was flashing on and off intermittently with a full tank of gas. The gauge reads full while the light was flashing. I am assuming the light means low fuel. So I continued to ride for about 40 miles. Today I jumped on the bike to go to work, turned on the ignition and the fuel light did not turn on during its "lamp test." It did not flash once on the ride in either. Is this a loose connection at the sending unit? If so, wouldn't my fuel gauge be out of wack as well?

The fuel level sensor and the low fuel sensor are two separate things, feeding two different sensors over two different wires.

If you have a short on the wire going to the low fuel sensor, it will turn the light on.

Also double check your grounds. Had strange behavior of my gauge caused by a loose ground at the battery.
