Installed and being used on a running motor is the only reliable test I believe which can be done for Atoms or Nova II modules. Either they work or they don’t. The heart of the Atom is a Mosfet or Darlington transistor with several caps and resistors in the circuitry and the way they are laid out, it’s impossible to test each component individually. From experience, I don’t think you will have good and lasting results using a Nova II in an OMC mag.
Here’s a link to an old thread about the Atoms: https://aomci.org/forums/topic/how-do-atom-computer-ignition-modules-work/
Thanks to Debe for the following photos he supplied after reverse engineering an Atom module.
