It's been so long--over 15 minutes--that I don't remember for sure, but 
I might have put an 'extra' loop in the pickup terminal. And I do recall 
the wire has to be oriented in one direction (not the other).

                      Subject: [Healeys] Tach rebuild<br>
                      <br>
                      Hi Listers:<br>
                      <br>
                      The tach on  my BJ8 does not show the correct
                      RPMs.  On a cool morning it shows what I believe
                      is fairly close to the right numbers, but as the
                      car warm, or the day warms, it reads higher and
                      higher for the same speed.  I know it is not the
                      clutch slipping.   I saw some articles in Healey
                      Marque magazine showing how to rebuild and test
                      them, but it requires a oscilloscope and some
                      other specialized equipment I don't have, so I'm
                      wondering if you guys have a recommendation for
                      someone that might rebuild them.<br>
                      <br>
                      I imagine there is also some info in the archives,
                      but my antivirus software flags the archive site
                      as a malicious website and doesn't want to let me
                      access it.<br>
                      <br>
                      Thanks for any info.<br>
