hiya ford lovers ,my xw has got a few mods some bodgy some good ive put a coupe tank in the boot well which had to be butchered to slide in and got a std pickup for the sender off a xy and bent the rod to dip down ,still wont get a reading on the guage which is xt dash std.ive tried all wires that the books diagrams says yellow from memory even earthed the panel whats wrong here?
Have you checked that the sender is OK?
Multimeter between the connection on the sender and earth should read between 13 and 90 ohms as you move the float thing up and down (I think they are the right numbers - close anyhow)
Have you checked that the gauge is OK?
If you earth the tag on the fuel gauge that goes to the sender, the gauge should read full (providing the gauge is powered up)
Also, have you checked that the wire from the tank to the gauge is OK?
Pull the wire off the sender, with the ignition on, you should see voltage between the wire at the tank end and earth
