[T3] ignition wire resistance

[Dave Hall]

I think all the wires I've had in my air-cooled VWs have been stranded
copper.  The '59 Beetle had them too, but the caps were unsuppressed (no
resistors there) and made a radio impossible to use.  I think in '61 VW
started using red carbon-filled leads, which were notorious for misfires
when the lead core became broken.

I suppose modern leads have different cores, but what's wrong with the
original material?  

Jim, is the spark plug wire you supply copper cored or 'self-suppressing'?

Subject: [T3] ignition wire resistance

Had an incident yesterday where a spark plug came loose (fairly new plug).
 I put it back in and found the wire had a crack in the boot.  So, I put an
old wire back on that #2 plug and I'm still having a misfire type symptom.
 The old wire checks out fine, but it's much higher resistance (by design)
than my current set of wires.

Old wire: about 9000 ohms per foot
new ones (bought 5 months ago); about 400 ohms per foot

So, I've got 3 new ones and 1 old.  Will this difference in resistance cause
my symptom or is it something else?  Spark plug looks perfect.

Thanks in advance.
