Pertronix Ignitor Explanation

[Tom and Amanda Lang <rustnrot@domain.elided>]

Landry's-Laundry-List had the following notation:

>I called them to find out why an old hand held analog Craftsman tachometer
>/ dwell meter I have won't correctly display the true engine rpm since
>installing the Ignitor.

John, that was an excellent explanation.  It also is convincing enough to
me to explain why my cheap voltage-seeking tachometer won't read correctly
on the AMC 258 on the RHD Scout.  This engine has a Mallory Unilite
distributor that probably utilizes a similar circuit to the Pertronix.  I
*do* know this; I got poked when I touched the *primary* of the coil.  Felt
like about 400 VDC <bg>.

Oh, and John, thanks for the comment about "Going Postal"
