Series 3 - Electrical Issues

Hi Folks,
I noticed a new quirk a couple of days ago with my Series 3 in that when I turn on my lights, rather inconveniently my dash catches fire!

Driving along the road I noticed smoke coming from behind the gauge panel, at first I thought it was the heater but after pulling over to take of the panel I noticed that it was the wiring to the lights that's was smouldering. Having replaced this the same thing is happening again, I assume I may have some sort of earth issue?

On the plus side and in typical Landrover fashion this fault has managed to somehow fix my broken horn

Any advice would be greatly appreciated.

I doubt if it is an earth fault, more like a live supply cable fault. The insulation starts getting brittle on old wiring and all the vibration eventually causes a short. Or a spade connector has come loose and is arcing to earth. The burnt wires should point you in the right direction to finding the culprit
