[Healeys] Lucas Sports Coil

[josef-eckert at t-online.de]

Perhaps these early coils have a different resistance. I have never checked 
that. LUCAS LA12 coils should have a resistance around 3 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.

  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 correct?
