With the final testing of the wiring behind the dash panel complete and the new LED bulbs (which arrived today) installed, it was time to screw home the panel and finally loose sight of “grannies knitting”. A major milestone for me. I suspect it will be off again at some point though….
After I’d completed the wiring for the dash lights (and had the courage to turn the key) nothing actually worked…. but nothing caught fire 🙂
In these older vehicles it is possible to switch the dashboard lights on and off. (anyone know why a civilian vehicle would require this?) It turned out that both of the brass terminals on the switch were heavily corroded and needed a clean up. 5 mins to remove the switch and wiring. 5 mins to clean the terminals with some emery cloth. 5 mins to refit and hey presto…. LIGHT 🙂
The 3 warning lights, high beam warning lamp and indicator tell-tale also got the LED treatment. Its worth noting that LEDs are polarity sensitive. With a positive earth vehicle the “lead” terminal on the end of the LED bulb must be connected to earth. The other way round and it will not work.
With little battery left on my phone I didn’t take many pictures of this one.

HI there, this post is quite a few years old. However, I am doing the same kind of job presently for my 1982 SIII SWB Diesel. I learnt recently that it is not a good idea to put one of these LED bulbs into the voltage / charge control warning light. I did this, and I found that the generator did not charge at all, at low revs. Stepping on the gas pedal got it to start charging, but at idle no way.
I discussed this with the LRUK forum – and somebody told me that the LED bulbs do not create enough amperage through themselves, to exite the generator.
I changed this one back to the original bulb, and charging worked as before, absolutely normal and as it should be. I was not aware of this issue, before learning it from the forum. Maybe worth to know, for some of the readers of this web site.
… by the way, nice rebuild job this one, and nicely put together here! 👍 Christian.
