Fuel Sender Wire

[Mark B]

Hey All,

Just wondering if anyone happens to know, off the top o their head, where i might find the fuel sender wire coming from the back of the dash? ie. what color it is and which wiring harness it's on etc. Or if anyone has found it in the manual. Or can tell me which page to look on..... I'm running the original bedford guage and sender.

Basically i know the guage works and i have taken the sender out and tested it. so therefore i am guessing that the wire betweent the guage and sender is shot...

Anyone had to trace this wire before and happend to know which color/where it is?

Cheers!

u might wanna chq to make sure the straps holding the fuel tank arnt shorting out the gauge. You should have rubber straps top and bottom.

Sorry but the straps don't have any effect. The sender unit itself has the sender wire attached and an earth wire to complete the circuit or at least it should. That may be the problem if it is missing.

If you give us some of the symptoms of the fault we may be able to help you more.

Mark the colour wire you are looking for is green with a black stripe and is terminated at your instrument plug (the one that plugs into your instrument cluster) and at the other end on top of your fuel tank to the fuel sender. It is also terminated in your fire wall plug set. So far as my experience goes, and as long as no one has changed the loom, does not change colour from start to finish. If it dosent go the first test to do, to test continuity of the loom is disconnect it from the sender at the tank. Then turn the key to on and touch the wire to earth, if the gauge deflects full scale then the loom is fine and fault lies with the sender and warrants further investigation. If it does not then you have a loom fault. First place to look would be the fire wall connectors, as these are notorius for problems. One other thing to try/check is some bedfords have a black earth wire that goes under one of the sender screws and is screwed to the chassis at the other end. Sometimes these are disconnected, broken or give poor conductivity, just another thing to check or add if you don't have one.
I think from previous posts I have established yours is a 76, the same as mine so would expect the loom to be the same.
hope this helps
cheers Jeff

Awesome, thanks guys & CFJEFF, will give it a go..gives me a lot more info to tackle it which is great  my sender doesn't have screws on it, it twists into place. there is no visible earth wire touching the sender unit..maybe the tank itself is not earthed properly..I can test this now that i know the colors and where to troubleshoot .. Thanks BUGA's !

i had an old xp ute where the sender twisted  into the tank & earthed, only wasnt earthing so i soldered a wire on outside of sender & earthed it from there... worked a treat for 14 years, till the rust won an had to retire her for present workhorse " puff the tragic wagon"
