Electronic Tachometer Adapter

[Polymer-2]

I uploaded a PDF for a tach adapter to my web site. It allows you to use a tach/dwell meter for tune-ups or just convert to an electronic tach on engines with 2 coils. Use the 4 cylinder range or use the 8 cylinder range and double the reading.

I received a few questions on the adapter so I updated the article with more pictures.
