Can't see the picture you've tried to post.

If the other wire from the bulb goes to ground, I'd suspect the yellow dashed wire would be going +Ve to light the bulb up normally.

On the K3, when the fuel is low the thermistor in the tank grounds the wire from the warning light. So with it disconnected, there should be a few volts on the signal wire.

the ahh the pic worked but now dosn't

the diagram dosn't show the earth going to the bulb (the diagram is rubbish)

when the ignition is on the bulb should light up, but dosn't have changed the bulb for another and still the same.
