And as the Orange warning light came on, then that tells me the the tank sender is working OK.!

Can anyone HELP!

I'm not sure about that. I don't know exactly how the sender works but it could be functioning from half tank to empty but not working in the half to full range so it could still be a sender problem or maybe a bad connection. Have you had the tank off recently?

 

Hi Philmore. No I have not had the tank off, it did work,somewhat at first (when I got the bike) but it doesn't work at all now no matter how much is in the tank! As i said the warning light comes on when empty so the connection must be OK - well I would assume so!!

 

I can't shed any light on the subject, but will add that my bike rarely shows anywhere close to full. I will typically fill it close to the end of a ride and even when it has set for awhile, when I next ride it's not showing much over half full. I can go out for, say, a sixty mile ride and have a little more gas showing when I got back then when I left. But the last half seems pretty accurate and the reserve light works, so way better than popping the cap and sloshing it.

 

The fuel indicator works very well on my bike, unlike some other bikes I've had where just sitting on the sidestand for a while or leaning very aggressively in turns is enough to change the readout. From your description, it sounds like yours is broken. There should be no delay in the bike "recognizing" that its been fueled up, the indicator works off a little float in the tank. As soon as the float is raised up, it should be sending the signal to the gauge to identify that. If its not, its probably stuck or failed in some other way. Your dealer may have been hoping that riding would knock it loose, which can happen, but since its been more than 2 full tanks now, and you've almost run out of fuel, time to go back and get it looked at properly.

If you dont have warranty or want to fix it yourself, first step would be tracing the wires back as far as you can, to make sure the signal is being sent. If the wires check out, you can remove the sender from the tank and manipulate the float manually and see if that changes the resistance reading on the wires. If not, the unit is faulty. If so, it may have just been jammed up.

 

Has the OEM clutch lever been replaced with an after market lever? Often the replacement levers lack a small tab that engages a switch on the clutch lever housing. It's this switch that has to be actuated after refueling to start the process of updating the fuel remaining bars and miles to empty display. This is the same switch that turns off the cruise control, and is used to confirm the switch from one riding mode to another when moving.

 

is a plunger switch, the sort which is there for the brake light.

 

The clutch switch tells the ECU to run in neutral map, which reduces power so you can't get full throttle (to prevent you screaming the engine with no load) and it disables the fuel usage calculation function (as it assumes you're getting zero mpg when stationary).
So yes, the switch plays an important part in the running of the bike, and this is the most common cause of the fuel gauges not working on the WC Triumphs.
The levers for the Thruxton are not the same as those for the Street Triple and other Triumph's, so you have to be very careful buying after-market levers to make sure the switch plates are in the same place... as you found

 

fuel gauge problems.



Hi jsobell. i have fixed the problem,(on my BONNEVILLE) but thanks for the explanation it saves a lot of ifs and buts.
The levers are OEM Triumph but probably NOT for the Bonneville, as theas come with a milled recess where the switch tab should be. So I made the Tab out of Aluminum that fitted inside the recess (tight fit) and glued it in with thread lock.
Looks quit profesional if i say so myself!!0 and works a treat.
Thanks again jsobell. best regards.:smile2:

Hi guys. A friend and I are both having a different problem. Our bike are Tiger Explorer XCx. Mine is 2017 and his is 2016. Both with original levers.

Our fuel gauge works perfectly from full up to half tank. After this, it shows no bars, the orange light comes up and the milage to fuel goes to 0 km.

Everything else is working fine. I can start the bike with no problem, change the riding modes while moving after pressing the clutch and so on.

I have removed the battery cables overnight, but that didn't solved the issue.

Any idea on what can be the problem?
