Reply To: Fuel Gauge

Back in 2014 there was some discussion on this forum which points to Floating Power, Volume 28, Issue Number 5 (Nov / Dec 2004) – page 14 and 15 have an article by Alec Bilney

Just to round this off with a French System problem, having read the old articles I now have a working gauge. Followed the guide and found the sender was fine at 120 ohms but would not work in the car then realised what I had actually done (eventually).

On the 3 retaining screws, sender to the tank, I had a fibre washer under the heads to avoid any potential leak so the earth wire was only touching the screw which was going right through the centre of the sender, into the tank top so the earth wire was not actually earthing the sender unit but the tank……..

Removed the fibre washer under the earth lead and….. the gauge works again.

So simple a thing, but ever so frustrating trying to figure out why it wouldn’t work but the old guides got me there eventually 🙂
