Hi Schuppi

I wonder if you can give me some help here.

Have a similar problem with a K1300S that's in our workshop. No reading on the cluster even though I left it with ignition on, for 2 days, straight. Had to even plug a battery charger to keep the battery close to 13V during the procedure. Also cable ties the floater to the max position to ensure there is absolutely no movement.

With the GS911 I can read the "Fuel level sense" voltage and it goes for 0.24V to 0.1/0V as I move the fuel gauge floater so I know the bike sees its working but it has failed to display the fuel level on the dash.

Any advice will be appreciated. Thanks.

Hello
If there is a floater mounted, please read the measurements
disconnect connector
STVB X9220   Pin 2+3 for low level 87,3Ω - 89,9Ω
STVB X9220   Pin 2+3 for full level 2,6Ω - 4,3Ω

...if I'm right, because there is no wiring diagram :-\

And remember, some of these needs to be driven to show the new level

Thank you Schuppi.

I have 86.1Ω at low and 3.6Ω at high level so I guess the guage is all ok!

Any other tips?

Hello
What's about reading the Real-time values in the cluster? Are there any hints for this?
Gauge tests > for verifying of dial gauge

ZFE Central Vehicle Electronics Controller Real-time values?
Cable tests with wiring diagram

Yes I checked all.

All segments work on the Instrument cluster (the fuel gauge consists of a number of bars on the left side on the LCD and all the bars lit us when I did the dial test too and all work ok)

Also did the real time values for the Fuel Sense voltage and the values showed a change that was consistent with the floater.

I am at a loss!
