I00e's were originaly 6volt and Positive earth sould to me like you have not fitted a resistor to drop the voltage to make it compatable with the instuments and/or reversed the polarity on the gauges! So there is a good chance that the gauge is now fried, sorry

What exactly have you connected the extra earth too? Sounds like the sender wire is now shorted to earth,

To clarify, Fuel guages are not polarity sensitive. When you swap from pos earth to neg earth, they still work as they did before. Duncan It sounds like yourse has the wrong sender, or guage. As some sender, guage combinations work thus, with the float down (empty) the setup has high resistance, and other combinations are oposite, Float up high resistance (full) I know this cus I cam across it with a Moggy, early Moggy was one way and late was tother, and someone had allready been there and swaped to the other way, and when we ploped on the correct year sender, the guage when arse about face. I say we cus 57 Ford, my little bald headed compardray was there to.
Homer, We need to know from the start what the story is. What was the guage doing that made you want to get a new one, and what you did from that point on. This way we can stop picking at staws.

100E's have never been 6 volt! They were 12 from the factory! I think there might be a gauge issue.
Yep you are right sorry head up my arse and too many projects

The thing you desrcibe, could be a voltage stabiliser. Ford went over to 5 volt guages in about 64 ish,from 10 volt. (at least on the Mk1 Cortina) I'd think Mk1 Escort would be 5 volt guages, this voltage stabiliser is the chap that drops the 12 volt down to 5 volts. Should be about 1" by 1/2", one screw at one end and a pair of twin spade terminals, one twin male terminal and one twin female terminal. Sound familiar? One twin is goes to ignition live and one to guages, Should be marked B for ignition and I for instaments. If my memory serves me right.
Have a look and see.

It's highly possible the gauge will simply not work with the original sender. Fords using varying voltage on their instruments through the ages and as Martin has pointed out somethimes different sendesr as well. What is the voltage stabiliser fitted to , part of the 100E or part of the Escort instrumentation?
