Ignition warning light only glows dimly
Discussion
Just re-wired my 1955 car with a new loom, re-conditioned dynamo and new (old stock) voltage regulator.
I realise that the voltage regulator will need to be set up, but when I switch the ignition on the ignition light only glows dimly and doesn't go out. Everything else works fine (if I close the cut out contacts on the voltage regulator with the ignition turned off the ignition light shines brightly).
I may have mis-wired something, but I can't think what.
Has anybody any bright ideas?

Since the ignition warning light is wired across the cutout, closing the cutout's points should result in the light going out.
The usual connection is a white wire from the IG terminal of the ignition switch and a yellow wire to the D terminal of the control box.
Unless Aston Martin did it differently from other Lucas users!

By "ignition light", I presume you mean the charge light (or lack-of-charge light)?
You may call it that, presumably because your relatively modern car's handbook does so, and that is more or less what it does, but the device asked about (and which my previous reply was supposed to help with)was called the Ignition Warning Light in period. Ignition light is an acceptable shorthand for that, I'd say.Allan L said:

That's how Aston did it tooThe usual connection is a white wire from the IG terminal of the ignition switch and a yellow wire to the D terminal of the control box.

Maybe they do. That doesn't mean it is one, any more than the other one which is often referred to as the "ignition light" - oil pressure...
Umm, my oil warning light has OIL written next to it. My "Lack of charge warning light" as you snappily call it has IGN next to it... IGN being short for ignition...AndyDRZ said:

That's nice, dear.So - what does it tell you? Does it tell you that your ignition's on? Or does it tell you that the charging circuit isn't?

It tells me that you tried to be pedantic about something that was clear to all involved and you've been called out on it.
If somebody wants help on why a particular warning light doesn't work, it does help if we're all clear on what that warning light is trying to tell you. No more than that.TooMany2cvs said:

No more than that.This "classic car" electrical business is reasonably easy to understand, and using the terminology of the day is part of that - it's what they use on the wiring diagrams, for example.
