Daimler V8-250’s just come back from having a new headlining and having the steering looked at, which meant removal of the steering column, by 2 different firms and now I’ve got no interior lights.
My meter shows 12V on both terminals inside te lights so it’s the path to earth that’s the problem.
I’ve looked at the only wiring diagram I’ve got (for a Jaguar) and all the lights have separate earths, which won’t explain why they all don’t work - I would expect a failed common earth to be the problem.
Does anyone know the actual routing of the earth wires? And are they commoned?
And in case it makes a difference - which I can’t see how - the instrument lights never worked.
