Thread: faulty fuel gauge

It would help if we knew which model Landrover you have. Guessing that it is a Series 3, the most likely problem is faulty earthing on the voltage stabiliser, located on the back of the speedo. If it is a Perentie, the most likely problem is that the gauge is not properly earthed.

Hope this helps,

John

It is a Perentie i have tested all connections for continuity to the chassis and all seemed fine to me but I am not a auto leco may have to test again.

just found my gauge lights also do not work could this be related

That strongly suggests that your problem is the earth to the instruments (does switching the instrument lights on and off change the reading? Remembering to allow for the slow response of the gauge). I predict your engine temperature gauge is misbehaving as well.

In my similar vintage civilian 110 the problem was that all the earth leads for the gauges end in tags stacked under one of the nuts securing the speedo, with another tag on a wire to earth. This nut was loose, and the fix was to tighten it, clamping the tags together again.

Hope this helps,

I will check when missus gets home as 3 kids and my head in a dashboard don't work well my temp gauge works fine so that's why I am puzzeld

Gauge lights fixed was faulty dimmer so bypassed with a spare terminal I found

Sounds like the same issue I had with mine.
The sender unit had stopped working and only registered 1/4 tank or full.
The sender is available from LR but make sure you are sitting down when they tell you the price.
I am thinking about having the old one rebuilt.
