Fred ? glad you got it sorted out.

I doubt that the problem was the black/white wire at the battery switch.  The 
sole purpose of that wire is to ground the ignition when the switch is turned 
off thereby keeping the engine from possibly running on the generator. (thanks 
to our old friend Norman Nock for teaching me this bit of wisdom).

The other end of the wire goes to the ignition coil.  If the wire is 
disconnected and taped off, the engine still cranks and runs as normal.  If the 
wire breaks and disconnects in the trunk, it would have to short to ground 
continuously for the engine to stop, but everything else would still ?light 
up?, including the starter solenoid.  If you still feel like messing with it, 
you could easily prove all this out to yourself.  In fact, a lot of people I 
know have intentionally disconnected this wire in order to avoid the 
possibility of the engine suddenly quitting from it shorting to ground anywhere 
from the switch to the coil inside the harness under the car. (I don?t 
recommend doing this).

Your problem was almost certainly a bit of corrosion on one or both of the 
battery posts.  I?ve had this happen to me ? everything goes completely dark ? 
nothing works.  everything looks clean, but servicing the posts and terminals 
gets it all happy again.  Makes a good argument for regular battery maintenance.

Hope this gets people thinking.

Cheers,

Okay guys, lots of informed thoughts on my no start problem. 

I went to the battery cut off switch in the trunk and found that the 
white/black wire was actually broken at the very end of the insulation.  The 
wire looked as through it was connected but actually wasn`t.  I stripped the 
wire and inserted it into the switch connector and the car started!  I turned 
the car off and restarted it multiple times just to make sure.  The problem 
seems resolved.

While I was back there, I tightened all of the other switch connections and 
thoroughly cleaned the battery terminals.  So, my hope is the car will start 
properly.

The first person to suggest the white/black wire possibility was Don Day.  I 
didn't think that could be the problem but after Len Hartnett and Steve Byers 
also suggested the same wire, I checked and there it was.

So many thanks to the allmost 20 people on the list who responded, all with 
thoughtful recommendations, including cleaning the crap out of the terminals.

Thanks to everone, what a list!

Fred
