Fuel Tank Wiring

[deano266]

Hi I have a super spec and the fuel guage Isn't reading anything. There is no power to the tank for the fuel level float and was wondering if anyone has the wiring diagram for this section and any ideas where it comes from as it is a sea of wires behind the dash. Cheers

Not sure on a Super spec, but most gauges are

 

power to one side of gauge, other side of gauge is lead to tank sender then to earth.

 

Take the lead off the sender and pace it to earth and you should get a full fuel gauge reading.

On the standard Superspec with the Escort Instrument Panel there are 3 connections on the Black multiplug

 

Pin 1 (green) +12 V Ignition switched and goes to the B+ terminal on the Fuel Gauge

Pin 5 (black) Earth for various things including Fuel Gauge

Pin 6 (white) From the sender and goes to the S terminal on the Fuel Gauge

 

And on mine it works backwards

 

Hope that helps.

I have the blue and white multiplug on the back of our instrument panel. It would be great if there was a full wiring loom kit

No such luck. All we have is the crude hand drawn sheet that showed what to plug where. Here is what I have discovered so far:

If you can add anything to we would all be grateful

I found a broken connection on the back of the escort dash. Connected the two via some solder and bingo. Got a reading.

 

However using a live tester the live is quite weak. Could this be break some where or is that normal

I'm not much of a auto electrician but I have mainly been doing things to just make the damn thing work haha
