Hello All, I am trying to figure out how the 717 engine knows when to fire the spark? Where is the pick up located ?? Is there a way to test if it is working? I've done the 787s but the 717 is not the same. Is the pick up or trigger in this photo?? I want to do some testing as I have a few engines to complete and one to test. I'm doing research on this and if I find info I'll post it here of course. I'm just hoping someone on the forum is familiar and can point me in the correct direction. Help is always appreciated.
