New member needs help with fuel gauge not working

The wires you can see I can only imagine is for fuel pump only a feed wire and a earth wire I cannot see that the tank is earthed on its fixing to the frame of bike.

 

http://www.triumphtalk.com/threads/tiger-800-800xc-wiring-diagram.13038/ I have found this wiring diagram please look at number 15 fuel tank sender 2 wires and 29 fuel pump also 2 wires you are missing 2 wires instead of 1.

 

No it looks as if it has a feed wire going into sensor measure voltage in and measure voltage out of sensor with a digital volt meter as you move float up and down voltage should alter on one wire and the other wire should read a constant voltage ecu sends message to instrument pack.

 

At this point I would have bought a dipstick!! I hate lectrix!

 

Can you tell me what DC voltage you have got going to sensor on pink and green wire with a digital voltmeter with ignition on ?

 

I have only a low fuel light on my bike when light comes on I put petrol in who needs a gauge, my previous bike had no light or gauge just a reserve tap when petrol runs out turn to reserve, why is life getting more complicated now on today's bikes you have a sensor a electronic engine control module a Can bus and a digital display and hard wiring all to control a fuel gauge the technology has gone berserk.

 

OK Matt if you have not tried it yet then i think when you get tank off again in the future just check to see what voltage you have there, you never know it may just start working again without doing anything.

 

Yippee !!!!!! Well done Matt

And well done to Mr Steve LOVATT.

 

A friend of mine has stalled his 800 several times but had no slow start issues

 

May be worth checking and cleaning frame / earth connnections

 

Well spotted Steve I would never of thought a clutch lever switch would have any connection to a fuel gauge I have no understanding why it should ??? saved Matt from buying a new jap bike.
