To be correct. Wernher von Braun was a Mechanical Engineer, not a 
Physicist. He studied at the University I studied many years later, at 
Technical University Berlin.[wink]

Sure he was, like Wernher vaon Braun.

Don’t quote me.

Then my answer is wrong. Here I am thinking "not" imperial.
Some (stupid) people may not know. To make it clear. Ohm is a SI-Unit. 
Georg Simon Ohm was a German Physicist. ;-)

I would never deem to use anything but Imperial Ohms.�

  Regarding the coil resistance

  I pulled out my Fluke meter and got exactly the same results....  these
  are B12 coils used on the early BN1 and many other cars including the
  Jaguar XK120.

  Turns out that primary resistance between 4.2 and 4.6 is actually correct
  for these, unlike the later styles.


  You learn something every day..

   Well that's really weird because the one on my car reads 4.6 and works
   fine ... has for ages ... I think I might have to check my ohmmeter �

    Primary resistance of 2.7 to 3.3 Ohms is right. It doesn´t matter if
    its an ordinary or a so called Sports Coil. When its 4.5 to 5.5 Ohms
    the coil is gone. You can bin it.

    2.8 seems low to me Michael. I have some original early 100 coils that
    I'm just cleaning up to put on Ebay and they show readings of around
    4.5 - 5.5. 

    Of course that might be a difference between regular and sport coils.

     I have a period Lucas Sports Coil type SA-12 for my BN2.  I have not
     tried it yet.  Can anyone give me the specs on it?  I get a reading on
     my VOM of 2.8 ohms between the two outer connections and 9,400 ohms
     for the center to one outer connection.  Is this coil weak or is this
