The fuel gauge on my '08 12GS hasn't exactly been working properly for awhile. It reads full when I fill up but doesn't drop much, if at all, as I ride. Reads 215mi range, down to 192mi, then gradually climbs to 240mi to 260mi range - then stays there until I need to fill up again (appx 190mi per tank as I use my trip odo for my MTE). The fuel gauge worked fine for about 7K miles; I'd get the flashing low fuel message/yellow triangle etc, which would disappear once I filled up - just like it's supposed to.
So I have some time today and figure I'll take my BBQ igniter and, per the well-documented steps in this thread, go out and "fix" my wayward fuel gauge. I zapped the two center pins a couple of times and rolled the bike out to start it for a test ride. A minute or two after starting the fuel gauge reads empty, the flashing FUEL! warning and yellow triangle are displayed - which I didn't have BEFORE I tried the fix. Oh, and the tank is full! WTF!?
Looks like I succeeded in making mine worse than it was before. It was inaccurate as hell but at least I didn't have the flashing FUEL!/yellow triangle I have now. It pisses me off so much I think I'll take my 650L for a ride instead
Anyway.. Happy New Year!
