GARMIN fuel gauge blinking

[boaterjoe]

Hi all, I have an R-29 with Garmin 7612 and the fuel gauge "total fuel remaining" constantly blinks at 145 gals. I have reset the system, but it never changes. Can't find anything in the manual. Have others had this problem?
thanks

My R27 OB is doing the same. since I just filled the tank, so I know that the ~145 remaining gallons is accurate.

I can say I recently turned off audible alarms. I'm in my slip (which triggers the low water alert at low tides).

Just to follow-up, today I noticed that the blinking remaining fuel capacity stopped blinking when I turned the engine key on.

Quite often to get engine information the engine has to be on.
