Re: '73 hazard light switch

["Richard & Julie Arnold" <rarnold@domain.elided>]

Well folks, after tinkering and fiddling and becoming ever more familiar
with "Anita's" wiring problems (Anita Tension), it seems that Carl is
the man.  Once I got all the wires hooked up right, the directional
signals and flashers worked great; for about one trip around the
block...Gotta be ground.  This car must have sat for a while in a garage
with the wires disconnected.  All of the terminals have a light coating
of oxygenation on them.  Soooo, with all of the information gathered
from the digest, Julie, my meter, and I will spend a weekend of wire
reconditioning, mostly the black ones I'm sure.

By the way, I am color blind; Ahhh Julie, good thing she loves Alfas.

Thank you all for the excellent attention to my problem.  I'll be going
at it this evening.  I'll let you know how it turns out.

I was interested, and I am embarrassed to say, slightly amused by the
immediate sequential juxtaposition of Biba's reply to the hazard switch
wiring
question ("doubt if ANY ONE ON THIS ERUDITE DIGEST (oops, so sorry) can
answer
your question") with Carl R. Davis' succinct and complete answer. I
suspect
that at least part of the explanation for the difference could lie in
Davis
having, and/or Biba lacking, a list of the DIN wiring codes normally
used to
mark terminals. If I am wrong on this, I apologize. The list I have is
from an
AR Service Bulletin 66-02, June 1983. If it is incorrect, incomplete, or
has
been revised later I would be interested in any addenda from any source.
That
said, if any others who don't have it might find such information
useful, here
is what Alfa said DIN said:
