Can someone shed any light for me as to whether the orange fuel warning light is derived from the same fuel gauge sender as the fuel level meter. Looking at the schematic in the Haynes Manual would suggest the warning lamp has +12v potential at one end and when the wiper on the potentiometer of the fuel gauge is down (i.e. the fuel is low), then the potential to earth via the gauge is higher and so the lamp lights up.
I could be wrong here and Haynes have been known to print incorrect diagrams so thought someone here could help. Hopefully it's something simple as a faulty lamp in the instrument panel, but best be prepared in case it isn't!
Many thanks
