Gave the bike a little TLC over the weekend in the form of a wash and polish, and although the bike looks better for it, I now have an electrical problem. I didn't use a pressure washer or even a hose pipe, just two buckets and a wash mitt. I'm guessing that water has got into a connector somewhere as I now have a constantly on low fuel light (it was working perfectly fine previously). The light didn't come on immediately after I started the bike, it come on after about 5 miles - flickering at first and then fully on. I've ridden the bike all week since (~100 miles), expecting the water to dry out, but this hasn't worked. Also filled up the tank fully (even though wasn't low enough to trigger the light based on the mileage covered) and this also hasn't worked. Has anyone experienced the same issue, or have any suggestions as to where I should be looking to dry out? Sods law says its going to be somewhere not easily accessible.
Here you go. http://ducatiforum.co.uk/threads/fuel-warning-light-996bp.30625/ Mine fixed itself for the last 500mls or so. Happened again last ride though at start up, think it was a little crap stuck in the sensor as gunning it from the lights fixed it and as fine for the next 100mls. I'd just use the trip for a bit and see if it sorts itself.
Thanks for the link. Can't help but think some water has seeped into the wiring/connectors rather than crap in the tank. It just seems too coincidental. I'll wait and see what happens with a few more miles clocked up. Just find it annoying that the light is constantly lit every time I glance down.
I have this problem and suspect it's a broken earth wire near the clocks area. Sent from my iPhone using Tapatalk
Just to update on this if anyone searches in the future. Was stuck in traffic today for a solid 5 minutes in the sunshine, temperature was quite high and the heat soak was starting to cook my legs. Once I got going again after a few minutes riding the low fuel light turned itself off. So not sure if there was water somewhere that finally evaporated with the heat, or if there was crud in the sensor that feed itself, or even perhaps a short somewhere which has temporarily corrected itself. Whatever the reason, don't have the light illuminated now.
Ultimate test is to disconnect the plug to the fuel sensor (tank off I'm afraid) this should put the light out if it is a faulty sensor. Put a link across the two wires to in the plug that go to the sensor (should be the 2 thinner wires but worth looking on the wiring diagram first as the other 2 as they are the power to the fuel pump and you'll short it out) this should light the fuel light. If so it's the sensor that's playing up - use a multimeter across the 2 wires to the sensor, you should have a circuit if the fuel is low and not if there's enough fuel in it. Sensor might be gummed up? and maybe repairable? but you'll need the fuel pump assembly out to do this, otherwise it's faulty. If you change it get an alloy nut instead of the chocolate one that Ducati fit...
