2014 Tiger 800XC - Fuel gauge issues! S.O.S.
« on: December 18, 2020, 02:47:29 PM »
Hi all,

Think I need your help and/or advice with a problem my tiger has started having.

To start with, my bike has not been run for the last 2 months. However, upon stating her the other day (no issues here), the bike abruptly shut off and could hear the fuel pump working. I switched off the ignition, switched it on again and the bike started with no issue whatsoever, however the fuel gauge was showing empty (tank was half full). It eventually recovered and showed the correct fuel level once again.

A similar thing happened once again the next day and resolved the same way as before. However, this time the ignition only clicked (just as when the battery is dead) it eventually started properly once again, fuel level recovered and all was fine and normal.

I have checked the battery voltage and it does seem low indeed (12.28v when bike is off). However, I am not sure if this could cause the issue with the fuel gauge and the bike shutting off thinking there is no fuel in the tank and the bike being able to switch the engine on anyways...

Any help or advice will be greatly appreciated!!! All runs perfectly except the engine switching off and fuel gauge resetting.

Thank you!!

I would charge the battery and try again - Tigers have like most bikes some electronic wizardy which I dont pretend to understand - however, like when you refill the bike, the gauge does not go to full straight away but after riding a short distance - I'm sure your bike is probably fine - best to ride it and see

How old is the battery? I wouldn't try to start mine with less than 12.5v.

Charge it up, see what v is day after, if not holding charge it's for the bin.

Thanks for your replies!

The battery is a couple of years old. From the owner before me.

Forgot to mention the 12.28v reading was after charging the battery...  It does seem the battery is dead but never thought the bike could start the engine but not power the ECU correctly... Hmmmmm

Trying to start with a duff battery can damage the sprag.....expensive!

Yes absolutely. Just realised the battery is pretty much dead....

Just hoping that is the cause of the issue, cannot think of anything else....

Not only the sprag, but there might be voltage-sensitive electrical components?
Correct battery voltage: elemental and important -- 12.8 V +.
Altho not always possible or convenient to check B+ -- and there may be less than full battery starts sometimes -- it can be a bit of a risk.
A voltmeter is your friend.
Good luck, hope you're OK after replacement.

Fuel level reading usually zeros out after battery removed, so it does tend to point to potentially battery, or main solenoid/fuse corrosion. I would remove the battery and check the solenoid condition, and battery leads etc.

ok great. Will definitely look into all connections, fuses and corrosion. Will also replace the battery.

Thanks for your feedback, will let you know how I get on!
