I am having a problem with the Slick 4220 mag on my project engine. I have the mag and harness installed on my engine, but when I turn it over by hand I am not getting any spark. The impulse coupling sounds like it is operating correctly. I don't have any experience working on mags so I'm not sure how to diagnose and fix the problem. The P lead on the mag is not connected and the engine is mounted on an engine stand and not on the airplane. Any help would be appreciated.
