I have two brand new German Prufrex coils here and can test the primaries on them for you to see what they read. If I dig out my Merc O Tronic, I will also see what they fire at but I can’t remember if it reads in amps or not like your Stephens unit does. Time to pull out the manual, which is nearby.
