Cortina Gauges, Sierra Senders!

[Guest The Stig]

Hi there just wandering if anyone can shed any light on this one for me, as im now unsure!

 

My S7 is fitted with the origional Cortina Mk4/5 instrument binicle, i am having trouble getting the Temp and fuel gauges to give any reading.

I know that they work cos when i ground the fuel sender wire and temp sender wire the gauges move accross the full scale.

 

I have fitted a new fuel sender from Kit Parts Direct, and changed the temp sender from a working sierra but still no readings

 

Did the Cortina use senders with differing resistance readings? i would of guessed that they would be the sane as sierra?

 

Any ideas welcome please

hi,make sure you dont use ptfe tape on the oil and temp senders because it will insulate the earth and get no reading.hth.

jess.

Hi,

If they're Cortina Gauges then you be needing Cortina senders.

Uncle Henry (in his wisdom) very rarely kept to standards such as this.

I doubt there's very little from the Cortina that ever made it onto the Sierra.

Hi there, no thers no ptfe tape, senders are on tapered thread so seal all ok.

This is a common problem with the Cortina instrument binicle.

On my S7 the temp gauges is very tempermental, it can go for months without working then for no reason at all it will work

again just fine for months. Same thing with the binicle on the Eagle RV too temp gauge dont work at all.

Tried different sender but still the same problem.

Fuel gauge on both work ok
