Fuel sender wiring

[Stut]

Would like a bit of help with my wiring on my 200 tdi defender. Having rebuilt the beast I have a few problems getting the electrics to work as they should. Thought I was being a smart arse when I attached labels to all the wires just next time I should use a permanent ink. But it seems like I have lost one wire completly. I assume there should be 3 wires from the fuel sender unit to the the wiring loom emerging from the dash. I have only 2 and thus the fuel gauge will only go just past half full.

Any Ideas as the Haynes is about as much use as a BMW X5.
P.S the rear wiper now works a treat (same pen used on the labels) Thanks.

No!

I also have a 200tdi defender and mine does not have 3 wires to the sender unit! Only a black and a green! I will be taking a look later, so will post some pics of how they fit if you like!

Mine is a 300Tdi but it also has just the 2 wires, and if i mind correctly black and green (or a black/green, something like that).

To see if the senders working correctly take the unit out of the tank and manually move the swing arm up and down full scale. You should see a like for like action on your fuel gauge.

I had a problem with mine and metred it out, metered out all the wiring from the tank to the rear of the gauge (which is easy to do), had the sender out of the tank and did resistance checks over the sender (again an easy check), gauge out of the dash and checked that out....blah blah blah.

Also check you have the correct wire in the correct terminal as if i mind correct i was able to only get the gauge to half full with the arm all the way up on the sender and this was due to me not having the wires in the correct terminal. Im sure there are 3 terminals but only 2 wires !. Just in case.

I found out i had a duff gauge allthough i did replace the sender as well.

I will check my wiring diagram to see what goes where.....

Just realised that if you type b l a h but close together like blah then blah appears.

When I put the beast back together I tried heaps or various positions with the 2 wires on the terminals and moving the float up and down and the best I could get was my current situation.

Any help as to what terminals the wires should be attached to would help determine where the problem is knowing that the wiring is ok.

Cheers guys.

aye but does it say which terminal they need to go to?

1. I assume you only have a rear tank?

2. The third wire is used for the fuel low warning light - the circuit diagram shows this as White/Slate (but this might not be the case) - you might also not have the fuel low warning light?

Possible colours are White, Green/Black, White/Slate and Black

Good luck!
