Help Understanding DPDT Diagrams

[Kayxero]

Here's where Im confused. Take a look at this Lindy Fralin picture of a DPDT pot when its knob is pointed upward. I clearly understand the layout.



Now look at these two Seymour Duncan diagrams. The first is for a DPDT series parallel as the Volume....the second pic is with the DPDT pot series parallel as the Tone. The wiring for the humbucker seems the same expect the pot seems flipped 180 degrees in the second diagram.



What I want to know is which lugs are which on these diagrams when compared to the Lindy Fralin photo. Which is lug 1? or Which is connection A or B? That will help me finally understand which connections go where when i look at any diagram. Thanks!

The 2nd Duncan diagram is oriented the same as the Fralin. The 1st Duncan Diagram is upside down. Typically, the contacts closest to the pot body are "made" when the knob is pulled.

So for the sake of my understanding...allow me to follow up.

In the 2nd Duncan diagram the red humbucker wire is going into Lug B as shown on the Fralin diagram? And the green wire is going into Lug D? Also, is which lug number is connecting that Tone pot to the Volume pot?

Sorry to need it dumbed down so much for me. Again Im new to this.

Yes. And the cap connects to middle lug of the pot and ground.

No prob. Glad to help.

And to elaborate . . . in the 2nd diagram, the contact pairs B & C and E & F are shorted, which shorts the red & white together for series mode. When pulled, A & B connect red to black, and D & E connect white to green. (Parallel mode.)

I totally understand now. Thanks so much again for the help.
