Thread: ISSUE: reverse lights/Diff lock warning light

I have the same issues with my 85RRC - they are low on my list, so haven't investigated either of these yet. Apparently they both worked before my father in law took it to a Rangie 'Specialist' and had some wiring 'fixed'. The stuff he wanted fixed then worked , but it created other problems . I will be looking at mine soon, and I will post the results, if you haven't got it sorted by then...

no worries mate. I'm led to believe these two particular things are wired in the same circuit....
I've had the reverse light switch out (from under the car attached to the top of the gear box). The diff lock engages but no light...
If I get it fixed I'll let you know.

Im no electrical expert but find the wiring related to the two and start at the bulb and work backwards till you find a section with power to it, then find where its loosing power and fix it.

Are the fuses all good?

I had the gear box replaced sometime ago and everything is plugged in as should be. I was hoping for a loom to be unplugged somewhere!
The engine check light illuminates, as does the parkbrake, highbeam, low fuel, indicators, hazards etc.
The reverse light switch terminals are riveted down but spinning/moving 360deg, the plunger is clean and moves in and out nicely, I've tried screwing it in/out but nothing is activating the lights.

I rang a reputable company about this today (who shall go unnamed), for some advice and to that person I spoke to: if you're reading this, get another job pal. You clearly hate talking. I never assumed you were an auto elec but bloody hell, you do work for a land-roverparts distributor!

fitted a new reverse light switch just now but the lights are not illuminating at all. However, the diff-lock warning light is on and stays on in all positions of the changer (won't turn off). Time to call an auto elec? The CDL light stays on also when the gear changer (manual) is not in reverse. It's just on no matter what and still no reverse lights.
There's 2 wires going into the far side of gear box (driver side) I cant tell what these wires are for and cant see where they go to exactly. Does any one know what they are for?
Also where are all the fuses/fusible links for the reverse lights?

Lights operating with new switch. The issue was that when the gear box was changed over, the three wiring looms, one for the gearbox temperature, one for reverse lights and one for the difflock were all in the wrong places. The only issue I have now is trying to locate the difflock switch from under the car as its totally obscured somewhere on the driver side. It's gonna have to stay unplugged for the time being until the day I can find it with my eyes closed and hand feeling in the dark. Thanks for your help everyone.

Cool, well done. You work faster than me - I still haven't got around to looking at mine - but I may do this weekend, as the weather looks good.

Another thing, I managed to solve water ingress problems. I had water coming into the footwells and on close inspection I found the rubber at the bottom of the windscreen had tucked itself into the plastic air cover. I used a small screw driver to lever it out. Also used silicone to seal the metal clips around the gutter. I left the car outside during the heavy downpour we had last week and not a drop inside.
