Re: Need some help! Double coil split
I probably should have drawn it like this:
Its just a question of the screw terminal coil being on top, or the stud coil being on top. As far as the diagram goes.
So with Kent's drawing, the red and white, and then green and black wires go to different terminals.
Edit: I'll try to make you a complete diagram tomorrow. That brings all the elements together.
Edit 2: Mistake in drawing corrected. (Thanks Kent S.)

Re: Need some help! Double coil split
oh no I understood your diagram Artie, its just Kent uploaded 2 pics at the end, and im just not sure what each one is meant to do...they both seem to accomplish the same thing (and im assuming the difference between his and yours is that his are humcancelling)

Re: Need some help! Double coil split
That's all you gotta do. When people speak of hot and ground on pups, we are speaking of positive vs. negative phase, not related to AC or DC in the convential sense that you are thinking of; ground also has multiple meanings, here it simply means audio common (not the same as chassis ground, or even earth ground, although it can be depending *what* it's is plugged in to). There is no rule that says that you have to make the starts of the coils *hot*and *ground*;or use the finishes as tap points ... you can use the exact opposite and still phase correctly with another pup (as well as itself). None of this you need to know really, if you want it to work. If you use either of my two then make the appropriate alterations (mag reverse, or reverse mount pup) and then following the corresponding wiring for that option.
Read the section on the main web site under FAQ, under the section explaining hum-cancelling ... In a nut shell you have to have an opposing magnetic polarity to create a hum-cancelling effect ... two norths won't do it, two souths won't do it ... you got to have one of each. Both of those SD's have the south magnetic polarity under the coil with the adjustable (screw) poles, the slug coils have the north ... since you want both slug (inner in this case) coils on, their mag poles are the same ... hence no hum-cancelling effect. So you must either flip the magnet on one pup (loosen the bottom base plate, push up the tape slightly, and wiggle the magnet out, turn it over and put it back in,tighten the base plate back, and pull the tape back in place), and then wire it differently ... or turn the pup around and then wire it differently again to get the correct coil you want. On the first image I posted you need to flip the magnet on the neck pup, then follow the wiring for it (as it is shown wired for a reversed mag), on the second one turn the neck pup so that the screws poles are toward the bridge, and then follow it's wiring.Nem said:

Re: Need some help! Double coil split
Electronically they are identical ........................................
On one you have to reverse the magnet on the neck pup; on the other you have to turn the neck pup around so it's mounted in reverse (screws towards the bridge ... that's why I drew screw heads there) ... both of these were done so that you could have hum-cancelling in all positions, and still have one end of the pups grounded at all times. Just pick which one you want to do (turning the pup is less work, but many like the look and subtle tone difference of the other) and wire it up accordingly. If you want to know more then go check stewmac's site under free info sheets for how humbuckers work, and also this site under FAQ.

:::::::Whispering to Art ::::::: *Hey ... , Art ... uh, concerning your latest diagram ... the *screw coil* has green and red leads; the *stud coil* black and white leads ... :smack: Just thought you should know ... gotta love typos ... :yell:

Re: Need some help! Double coil split
Three reasons:
1) To tap the correct coil (in this case turning off the correct one).
2) To use the type of tap I wanted (*hot*tap or *ground* tap).
3) To have the phase correct (with or without the magnet flip). ;-)

Yeah . . . a "typo" . . . dats the ticket! :laugh2: :laugh2:
I have my little "notebook" with all this info in it so I don't make these kind of mistakes. Apparently, it didn't work. :smack:

Re: Need some help! Double coil split
ok, sorry but regarding those 2 images kent posted: the first one you turn the magnet around and you end up with the 2 outer coils activated, on the second one you turn the whole pickup around and you get the 2 inner coils activated.....how do i wire it so I flip the magnet but get the INNER coils activated?

Re: Need some help! Double coil split
No, you get the inner coils with either diagram, the wiring is already done correctly for the given choice (magnet reversal, or reverse mounting), just follow the directions on the given choice ... better yet take it somewhere and have a tech do the wiring for you, as I think that would be your best choice.

Re: Need some help! Double coil split
I already covered that, go back and reread the posts...
Nem said:ok i understand it now
just one more question...is there any way to tell whether a pickup or combination of pickups is hum cancelling?

It HUMM's or it Don't Thro' your amp when your are not playin' but plugged in with your amp at normal volume. :smack:Nem said:

Re: Need some help! Double coil split
umm, i just got my pickups and im ready to start wiring everything up, i came back to the thread and the diagrams have disappeared
can you post them up again please? i didnt save them to the comp the first time cos i assumed theyd still be around when I got the pups....
