I am not familiar with that terminology, but my guess is that you are asking which pole is the one to be grounded on a spark coil. A typical spark coil from an old car will have one side of the secondary winding attached to either the case of the coil sometimes if it is a metal cased one, or to one of the two primary inputs. If the coil inputs are labeled then I believe it is connected to the one that normally goes to the points. But since the turns ratio is so high, you could use either one for the ground with very little difference.
