You posted a reasonable question and we came back with a confusing response. For this I apologize. I am going to attempt to summarize for clarity and to possibly answer your question. When the distributor points close, current builds up in the primary of the coil and produces a magnetic field which is stored energy. When the points open, the current suddenly ceases and the magnetic field collapses producing a sharp voltage spike across the primary winding. This large spike is stepped up across the secondary winding and fed to the distributor by the high tension wire. The terminal stud for the primary winding can be identified with a voltohm meter. With the meter set in the resistance scale, place one lead in the high tension socket of the coil and connect the other lead alternately to each of the terminal studs on the coil. The terminal stud with the highest resistance is to be connected to the wire going to the points. The other terminal stud is the primary and is to be connected to the the hot wire from the ignition switch.
