<div class="gmail_default" style="font-family: comic sans ms,sans-serif; font-size: small;">Regarding the coil resistance </div>
<div class="gmail_default" style="font-family: comic sans ms,sans-serif; font-size: small;">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.</div>

<div class="gmail_default" style="font-family: comic sans ms,sans-serif; font-size: small;">Turns out that primary resistance between 4.2 and 4.6 is actually correct for these, unlike the later styles.</div>

<p style="margin: 0px;"><span style="font-family: arial,helvetica,sans-serif; font-size: 10pt; color: #000000; text-decoration: none;">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.<br /></span></p>

<div dir="auto">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.
<div dir="auto">Of course that might be a difference between regular and sport coils.</div>

<div>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?</div>
