[Healeys] Possible explanation on the Petronix positive ground and Smith loop style Tach

[Len and/or Marge Hartnett]

I just crawled under my dash to take a look at the back of my tach.  I call
it one (1) loop.  Wire goes under clip, loops around and goes under again.
One loop, two wires under the clip.

Tach works fine although I did have to do the internal capacitor swap much
later when the readings started going off (see
http://www.healey6.com/Technical/Werner/BJ8%20Tachometer%20Reads%20High.pdf
on John Sim's site).

'67, BJ8, positive ground, Pertronix Ignitor LU162AP12.  Many years of
excellent service without any modification to the tach or wiring.
