The primary connections on the coil are the two low voltage (the + and -) terminals.
The two secondary connections are the high voltage output nipple, and the outer steel can that Bob M, your above statement is not totally correct as to my understanding of the physical make up of a coil. I agree that the first sentence is correct but leaves off additional connections. The primary windings are connected to the two studs marked + and -. One side of the secondary winding is connected internally to the stud that the ignition (switch)wire goes to and shares this internally with one side of the primary. The other lead on the secondary winding goes to the high tension nipple. With a good multimeter, a coil can be checked to verify which stud is the input for the primary by reading the resistance. From the high tension nipple read to one of the studs and remember the reading, then read to the other stud. The difference will be small. The larger reading is the primary and secondary windings in series. The smaller reading is the secondary winding by itself. The stud where this lower resistance reading occurred is the stud that gets voltage from the switch. I agree that the coil will work when wired incorrectly but if you know different why have less than optimum?

Old Time Threshing - by Anthony West. A lovely harvest evening late September 1947, I was a school boy, like all school boys I loved harvest time.
