External ignition amplifier connection - subpage of MembersPage/ChrisGerhardt/ChrisNotes

I bought a large capacitive discharge ignition (CDI) amp to strengthen my spark delivery, but help is needed to connect it to and make it work with genboard

Chris, several signs indicate that Mallory forgot to put a capacitor on the input. The fact that the manual say that you MUST keep the capacitor in a points setup is proof enough. Getting a points capacitor and fitting it between the trigg wire and gnd will most likely solve the problem. -Jörgen

Between Trigg wire and GND? Yes

If a missing capacitor causes the problem, I'd bet the capacitor must be in series (so the trigg wire does not directly connect to ignition module, but through a capacitor. This is not the case Value is a good question, the minimum I'd try is 10uF).I would definately use a capacitor meant for this, which means a capacitor for a car with points ignition. -Jörgen

Information for Mallory HyFire IVA CDI Box

All of the below information is available at the link below. It has wiring for multiple different types of setup. I simply want to trigger the Mallory Box Directly from Genboard IGBT. I am having trouble with lost spark triggering it from the Edelbrock igntion module so I want to eliminate extra wiring and parts.

Testing

Cranking the engine is not necessary,
