 Nah, they're too easy to make to keep.

 Sure, it's easy to fabricate a zero resistance wire.  At least within the tolerance of the $10 DVM's H-F sells.  ;-)

If you don't have a drawer full of those that you got for free, you aren't doing it right.  


But seriously, through 72 the TR6 has a 12 Volt coil (internally ballasted) and there is no intentional resistance in the coil wiring.  From 73 onwards the used a 6V coil with a ballast wire,  But it is not the wire between the coil and distributor so in either case a plain copper wire is used.

It took me a long time to wrap my head around the way that system actually works.  I finally got it, but I've still never actually seen the ballast wire.  Back in the day, I sold plenty of ceramic resistors for Chryslers, but I assume the wire is buried in the harness somewhere?
