Yes I know this has been asked 10000 times but I have searched, read everything I can find, followed all the advice, and I can't seem to work it out still.
Mini is a 1989 Mini 30. Clocks aren't original but they are the same model as original, and the fuel gauge used to work fine.
As it is today, when full, it sits about halfway, half tank is empty, empty is bottom of the gauge. I've been getting by just relying on that being correct but it's annoying me a bit now.
We have tried a new sender unit, no difference.
So I tried all the wiring at the sender end as follows:
"Use a short jumper wire between the green/black wire on the sending unit and the battery earth connection. If the gauge goes to "full" while the green/black wire is earthed then the problem will be with the sending unit or its earth connection. To determine which, remove the jumper wire from the battery and connect it to the black wire on the sending unit. If the gauge goes to full again, your problem is in the sending unit. If it does not go to full, the problem is with the black wire or its earth connection."
These steps did make a difference, but the gauge stops about 3/4 of the way. Initially it was more like 7/8 (1st pic), then I realised I had used about 10 litres yesterday so I went and topped it up. Came back tried again, now sits around 3/4 (2nd pic). I was hoping it would hit full...
I have also tried adding a wire to a known earth point rather than just the battery, exactly the same.
This would make me think it's the voltage stabiliser at the clock end, but the temp gauge works perfectly. So, any ideas/more things to try?!
