oes anyone have a schematic for a simple four pin HEI ignition module

Most 70's era street bikes would run from the 12V battery supply so you would
have to buy a kit suitable for this power supply. I don't know where you are but
here is one kit http://www.jaycar.com.au/productView.asp?ID=KC5442
The bike is 80's runs from the battery. They call it a CDI but it
isn't - runs from 12V with no HT generator coil - the module just has
4-5 components in it (potted in black goo) induction coil is ~3.5
ohms.

Doesn't take much to make a CD Ignition, see....
