A pointer to the circuit you looked at would be helpful, though
I haven't seen a "circuit" diagram and haven't mentioned that word until now. It was a parts diagram and list.
I've checked some more; it is a Ducati DCDI ignition (double capacitor discharge ignition), rather more complicated than the traditional self contained magneto type of the Lycoming. I understand there have been some issues with the Rotax's external connectors between the generator coils and the module and with the reliability of the modules themselves.
