Hi all,
Still investigating the kick back problem on my 912S, I have a question for electronic engineers:
The Rotax schematic shows two separate AWG18 shielded wires from the ignition modules to the ignition switches. On my aircraft, I have a twisted pair of wires, probably smaller than AWG18, inside a single braided shielding. Is it possible that this configuration cause interference between the two circuits so that when ignition A is active and ignition B is grounded, ignition B may produce some spark while I am cranking the engine?
Regards
Remi

Remi,
That is very highly unlikely. The whole purpose of the twisted pair is to reduce noise and interference.
