Although this one seems more inexplicable than most, I'm no longer surprised at the electrical surprises these old girls can provide. Your story about using a relay to address the resistor in the ignition circuit is interesting. When I was sorting out the new engine in mine I had to ensure a full 12 volt supply to the coil and my first idea was a relay triggered by the resistance wire but someone advised against this but I can't remember why. I ran a new resistance free wire from the ignition switch instead. Haven't had any problems on that front.
As I said above, I have bench tested the relay kit out of the car and it seems to misbehave in the same way it did in the car so I think its failed somehow and its just coincidence that it became apparent when I put the LED dash lights in. It could be a year since I turned the headlights on so the relay kit may have failed some time ago.
Anyway, I did put the lights on going through the tunnels on Australia Day and they worked fine with the original car wiring. I haven't got around to getting a new relay kit yet.
Thanks again.
