Joe,
When you said "brake light circuit," I assumed you were talking about the stop
lights. Oh, well, they say hell hath no fury like an unjustified assumption!
Looking through my GT6 schematics, I found no black/purple wire anywhere, and
made another foolish assumption. Often, on British wires, the stripe is as
large as the background, making it impossible to tell if the wire is
black/purple or purple/black, so I assumed Dee misread the colors. This is a
common error, and one that is very easy to make. On my GT6 schematics, the
brake failure switch/warning lamp wires are white and white/black, the same as
in a TR6 or an MGB. After your note, I pulled the few Spitfire schematics I
have, and found that the wire from the failure switch to the lamp is indeed
black/purple -- one of the few times that the color code on one British car
differs that much from another.
So, the question remains -- what is that wire with some black on it and some
purple on it? Did they change the GT6 wiring at some point, some with a
white/black wire and some with a black/purple wire for the failure switch? I
dunno! The schematics I have are labeled "GT6 Mark 1" and GT6 Plus."
If your Haynes manual shows black/purple for a Mark lll, then I guess that
settles that! Black/purple it is!
(Which reminds me of a joke I heard the other day. A chicken and an egg were
in bed, and the chicken was laying back smoking a cigarette. The egg looked
over and said, "well, I guess that settles that question once and for all")
With apologies for my error,
