This is absurd btw....I think they are on revision E now...that's what I gathered from Ducati Omaha's site, but i may be wrong.
I tried with a 15k resistor before my recent weekend away and the gauge didn't move off empty, I don't have a clue why either. I had thought 15k was outside the range of the new C sensor but it's not.. Will try again this week while the silly thing thinks it is nearly full with an empty tank..For what it's worth, it took me a long time to get the clock set, so the engine was off with the system energized for I don't know, maybe 5 minutes.
If it ends up throwing the error eventually, I'll disconnect it and bridge the pins on the harness side with a resistor as mentioned earlier in this thread, until Ducati releases yet another updated version.
I'm on my second C sensor in 3000 miles and this is exactly how mine behaves.Well, it happened to me tonight on my commute home from work. Stopped to fill up, light was on and bottom bar was blinking. Filled tank (3.9 gallons) turned bike on and it stayed at one bar and fuel light is on. Stayed like that the rest of my 17 mile ride home. Turned ignition off and on a few times but it just reads the same.
I tried that. It didn't do anything.SD, go into the setup menu as in my post above. It may update to full as soon as you enter the menu, mine's done it twice. If yours does too, then this smacks of a software issue. Maybe.
edit: Your bike however may not have the C version sensor depending on the build date. The C version was only released around the end of November 2014.
Sent you a PM, but for the benefit of others ... I know just enough about electronics/resistors to screw it up. Was the resistor you used below 5 Watt, 1 Watt, 1/2 Watt, 1/4 Watt, etc?
My eyesight is just bad enough that I can't make out the color codes on it.
The float inside is causing the sensor to fail. I coated it in fuel proof dope and let it cure for 3 days. Then I took my non working/fuel soaked float out of my bike, and installed the new one.
