I've read through a lot of old threads to get my reverse light working but I've hit a bit of a wall!
I got the old multimeter out and did some testing:
I have a phase 2 with the reversing light on the bottom valance.
The bulb is fine and the cabling from the passenger light cluster to the reversing light is fine. I tested by rewiring the brown loom so the revering light was powered from the fog light feed (swapped the red and orange cable over) and the bulb worked as it should.
As far as I can tell the is no voltage in the red cable in the brown loom at the back of the passenger light cluster.
The fuse is in tact and the other things running off fuse 1 (fuel gauge etc.) work fine.
From the wiring diagrams the problem must be between the fuse and the brown loom but I don't know where to look. From old threads people have said check the switch on the gearbox but I have not idea how to access that!
Any help would be much appreciated.
Cheers
Luke
