couple of weeks ago when I tried to turn the ignition switch on my 64
the entire switch rotated .. (and I honestly never noticed it being
loose at all) ... Anyway I now have two wires hanging loose from
under the dash.. The one that I can not figure out is coming out of
the condenser (looks like the condenser located inside a  distributor
...I ani't no electrician) ...  This condenser is mounted on the back
of the dash directly to the left of the ignition switch...

I have a 1963 Factory Manuel and I do have a Lectric limited laminated
electrical schematic for the 64  BUT I can not see where the wire from
the condenser is connected...

I got the car home BUT really screwed up my back in the process and I
have been seeing a Chiropractor for the last 3 weeks...I had an
appointment this morning...)...  Anyway the back is ALMOST good enough
for me to crawl under the dash and begin to sort things out...  Car of
course will not start ..its on the lift and I do not feel like
trailering it to the shop to wire one stinking wire..

Anyone out there that has a 64 with the transistorized ignition... ???

Hell when you get old and your body starts goiving you more trouble
then you feel like dealing with...

Regrets on the back.  ...ugly way to have a
switch fail!

"Diode" isn't here so here goes.

Bob, sounds like a radio suppression
capacitor.  In that era, they weren't
considered a part of the chassis wiring so
won't appear on a schematic.

The custom in the 50s & 60s was to include a
variety of suppression capacitors with the
radio and the installer would place them
(randomly at times) to get rid of electrical
noise.  Factory or dealer option would
probably have placed this one from the "cold"
side of the ignition switch to ground.
(Placing it on the hot (battery) side of the
switch would have enabled it to 'leak' and
discharge the battery.

At age >40, this capacitor isn't doing much
suppressing.  Value should be stamped on the
steel shell.  If not, .01 to .1 ufd at 200
volts should do the job.

Cheers & take it easy.  I did that to my back
messing with my daughter's VW years ago --
was down for nearly a month.

Bob, did you ever get this resolved and is the ignition stock (K66) or
after market?? I think PJ answered the "condenser" question and that
second wire can be the ground that GM puts at the base of their
ignition switch with a big wire eye(connector). It's rather frail and
much twisting can break it off.

As far as your decrepit body goes I was ready to trade mine off this
past month myself after 3 tries to break up a 5X9 centimeter kidney
stone. Lost to many good days to be out and about in this nice
weather. Brought back to the reality of it all when I lost 2 more
close friends in two weeks.

I found while working on my 63 coupe that it was easier to remove the
seat to allow easier access to the underdash area. Only 4 bolts and
it's gone, also gave me an opportunity to clean up popcorn, candy
wrappers and coins. Also helps to remove 6 screws that hold steering
wheel, too.

As we get older we have to work a little harder sometimes.

I have had enough experience of removing the drivers seat as the one
screw that holds the back rest to the bottom of the seat frame has
come loose a few times... last time it did that it was time for Lock
tite...

I do plan on going out and removing the seat and I may lower the
steering column if I need to... Really should not be a major problem I
just wish I had more "electricians smarts" ...   Actually the only
problems I have had with this car in the 7-8 years I have owned it
have all been electrical ...The headlight rotation switch which you
kindly send me.. one powere window switch and the headlight dimmer
switch...NOW the iginition switch which I think is not the switch
itself... Good thing is that the iginition switch and the power window
switch and the headlight dimmer switch are standard GM parts and were
very cheap ..that darn headlight rotation switchthat I got from you
was extremely expensive  (like 120 to 180 bucks new) since it was a
switch  That GM only used in Corvettes and then only for 5 years.... I
still own you big time for that...

That offer to buy the drinks is still on my agenda when I get up to
your neighborhood. Right now I'm in Red River, NM. My son is moving to
Wellesley, Mass. to teach at the College there so, maybe next year, we
will be coming that way to visit. If we do I'll let you know.

Dad...
Was at the chripractor again this morning BUT things are almost back
to normal I just want to give it a couple more days THEN I will remove
the saet and get under the Dash and figure it out one way or the
other,..  Car is completely stock and 99.9 percent correct (which BTW
is not my thing but since it is I plan on keeping it that way)...

I had major Surgery in December and again in  March (to undo the
Decembers Surgery which worked fantastically until the graft got
infected  and they had to rip it out  ) now with the back acting up
I'm more then a little frustrated...

I can borrow a trailer and trailer it in the one of the 2 places that
I trust to work on the car BUT  Part of this hobby is actually working
on a car..and being truthful I enjoy that part of the hobby BUT I'm
also  too cheap to pay someone to re-wire a darn switch.. . LOL
