I have a 1996 80 series on which the (OEM) rear diff lock stopped working last autumn. I (foolishly) assumed "actuator corroded up" and asked Exeter Gearbox Centre to replace it. They (wisely) did an electrical test first and said "it looks OK, but it isn't getting any power" and handed the problem back to me, so it seems that I have an electrical problem.
That was wet, cold and muddy then and - without a ramp or pit - I couldn't be bothered to crawl underneath and get cold and filthy; but this is warmer and drier now and I need to sort it out.
All the electrics seem to be working OK with centre and front diff locks operating correctly, and the relevant lights flashing / steady on the dash. However the centre light, which goes on first, definitely dims when I select rear, but doesn't dim when I move on to select front + rear, which suggests to me a full or partial short somewhere.
So I imagine I'm looking for a broken wire and/or rubbed through wire shorting out to chassis earth. I have the wiring diagram, but I have no idea where the cables run or - crucially - where they go through the bodywork.
Does anyone have any advice, tips or experience to offer?
Thanks in advance
