Jan, You seem to have some sort of personal issue anger here. You have received a lot of advice from quite a number of members over the years you have been a member of this forum. It would be nice if you could give something back and discuss genuine questions without sarcasm or anger showing through.
By the way, having read the Rotax manual, I noted that your description of the ignition system wasn't completely accurate and you admitted you weren't sure about it. You should already have the circuit diagram you asked me for. It's in the 912 manual, below the system description.
Regarding your question added in the edit. LT? As you told me to do, look it up for yourself and answer your own question.
