My ignition module A is firing only sparkplugs on TOP and ignition module B is firing spark plugs on the BOTTOM of the engine.
Due to MML of engine:
and on my system A is firing only TOP and B only bottom.
I have problem to find in manual correct connection diagram for my module and rotax 912.
I have module with one 4-pin connector and rest singles.
In manual I found only wiring diagram for rotax 914 (not 912) with this kind of modules and from this diagram A is working only twith TOP (as I have connected).
Maybe its missing diagram in manual or I missed something?
