Fuel Guage

[bob4026]

Hi all,

Gremlins seem to have got into my bike.... the fuel gauge isn't working now. Tank is 3/4 full but nothing showing on the digital gauge. Where should i be looking first please? Everything else on the cluster seems ok.... up to now, but the engine management (orange) light is on also. |Done the `dropping into gear with the sidestand down` trick thing, but it's still on.

Thanks very much for any guidance you can offer.

Clutch switch? You should not be able to start the bike without pulling in the clutch lever. Check if you can.

Checked that mate and it won't start unless i pull the clutch in.

Any chance you disconnected the battery cables? Updated the mapping? Connected Dealertool, Tigertool or TuneEcu?
After this the fuel gauge can read zero and will only start indicating after riding a few miles. This is mentioned in the handbook.
As for the EML light....if the light is still on after 3 start cycles it indicates a recurrent failure and OBD fault code(s) are stored.

Thanks pal,

It's now gone thru three cycles and the light has gone off, but the fuel gauge still isn't working. Its the one with the digital gradients next to the digital temp gauge, not the one that gives you `miles to empty`.

Cheers

You probably need to ride it for a couple of miles , the digital bars should start to increase slowly until they get to the level that's in the tank.
if it still doesn't show correct after a few miles you may need to run some fuel additive in the tank (redex)
its could be the float on the fuel level sensor is sticking so may need changing if a couple of tanks with redex doesn't cure it.
myself & others have had the same issue , the fuel gauge on the clocks is very slow to update sometimes.

Thank you all very much for your help with this, i'll get out for an hour this afternoon.

FYI all of the fuel readouts are linked, they all come from the same source - the ECU.  There is no direct link between the level sensor and the display on the dash.  What you see on the dash (including the bars on the 'fuel gauge') is an estimate from the ECU based on it's sensors including the ones telling it how the engine is being used etc.

Went for a ride this aft, only an hour or so but after five minutes or so, i got readings. Battery been disconnected for another job as it has been before but i'd never noticed this before.

Cheers for all the advice.
