Hi doc, this test aims to cut through the confusion by testing what is really important, jumping past all the things along the way that can make it right or wrong.
All that s really needed is to identify which pair of wires goes to which coil (which you know) and, getting the coils and the pickups in phase when they should be. Along the way, phase can be reversed, and re-reversed by changing any of magnet polarity, winding direction, start/finish, wire order etc. In phase just means consistent. If you reverse everything, it makes no difference to the sound, its only differences that count.
But, with your pickups, and knowing how you have a black/white slug pair and a red/green screw pair, it looks like there is a high chance that they are wired like Seymour Duncan, which is probably the most common scheme from other makes. So id suggest to assume that as a starting point, and prove if its true using the test. So lets assume that the black and red wires from each coil will be the ones nearest to hot from their respective coils, as would be for an SD pickup. (On the wiring diagram on your other thread, that would be labelled north start and south finish, but we don't really need to know that.)
If you are doing this test using a meter, put your red meter lead always to the black or the red pickup wire (the black meter lead going to white or green), and hopefully the meter will jump the same way. If you are doing it into a pc, then keep red and black going to the hot input and see that the pulse consistently always jumps up or always jumps down, but never reverses. If you can get everything jumping or pulsing the same way, then you are good to go.
Not sure if that made it any less confusing though....
