200tdi fuel sender wiring

[C18RCH]

Having converted my 110 to a 200tdi and put a new loom in which only seems to have one wire to the fuel sender, do I still need the old white a slate wire which seems to be redundant.

The white and slate wires at the front seem to be self contained within the dash.

Cheers,

white/slate is for low fuel warning, if your sender only has 2 terminals 12v feed & earth, just terminate the White/Slate wire & secure it safely out of the way.

The sender has green and black, earth and white and slate. The old loom (19j) had white and slate feeds from the sender to the dash. The new 200tdi white and slate terminates at the circuit board in the dash section of the loom so I assume white and slate is not required at the sender?

some models weren't fitted with the low fuel light wiring,

if there are only 2 terminals on the sender unit ---

a rigged stud = earth & a spade terminal, there isn't a connection for the wjite/slate wire,

if the sender has 3 terminals 2 spade & the rigged stud, then the gauge goes to black sleeved connection & white/slate to the red sleeved connection, earth to the stud,

whilst were on this one mines a 300 , no fuel reading have crossed the wires and gauge still not moved , dash light works for gauge , any ideas , is gauge knackered or is there another test I can do on gauge ?

[western]

most likely a dead gauge, as it doesn't react to any tests.

mate told me to check lives , so at the two spades on back of gauge there is def 12 v , got another gauge now to try , is there an earth for the fuel gauge /tank that I may have missed when doing build ??
