Need some help! Double coil split

Re: Need some help! Double coil split

hey i just started wiring this and noticed something...

ive chosen to reverse the magnet as opposed to the entire pickup so im using the first one, where the purple coils are active
but if you have the purple ones active you actually get the outer coils because you have the left one on the neck and the right one from the bridge....?
 
Re: Need some help! Double coil split

ok this is what i mean:

u see how i mean by the outside purple coils?
 
Re: Need some help! Double coil split

ok so the neck pickups NORTH coil must face the neck? how do u tell which is the north and which is the south?
 
Re: Need some help! Double coil split

I believe that north and south are slang terms more than technical ones. They simply refer to the coils that are up/down when a guitar is sitting on a stand.

Refer to this diagram: (Hold down the "SHIFT" key and click, to open in new window.)

North/South

Notice that one pup has the adjustable coil as "north", and the other has the stud coil as "north".

Generally, the normal way to install two humbuckers, is as in that diagram - neck adjustable up, bridge adjustable down.

Note also the labels on the wires, and use that to decide which coils you want paired together for your application.

ah ok gotchta! :)

by the way, when you flip the magnet, do you flip it lengthways or widthways?
 
Re: Need some help! Double coil split

well i finished wiring it exactly like your second diagram, but it doesnt work
it gives me a really loud buzz in every pickup position, the 2 end positions seem to work fine, they select the right humbuckers, but the middle position seems to give me the bridge humbucker AND one of the coils from the neck?

also, i just realised these humbuckers have 5 wires, not 4, they have a red, green, black, red, bare and WHITE, im assuming on those diagrams posted earlier you were meaning the bare wire with the light purple line? what do i do with the white wire?

Thats why it doesn't work. ;)

The bare wire is just connected to the metal plate. Its the shield, or think of it as another ground. Look again at that diagram I posted. The light gray line is the white wire. In Kent's diagrams, I believe its the violet wire. Obviously, you can't draw a white wire on a white background. ;)

Sorry for the confusion, I should've labeled it in the diagram.
(Correcting it now.)
 
Re: Need some help! Double coil split

oh i seeee! wow i feel stupid lol
ill quickly try that now then :D

oh and there seems to be a lot of stuff i need to earth: the bare wires, a white wire and a black wire, would it be ok to earth all of these to the same pot? or do they need to be earther to different pots?

Don't feel stupid for that. How would you know that violet or gray = white.
If you're really looking for something to feel dumb about, make it for tearing your guitar apart before reading all the Seymour Duncan FAQ's and tech tips. :laugh2:

Just kidding - we all start somewhere. ;)

Yes, the grounds can all go to the same pot, or connection. That is, what "ground" refers to in this case - a "common" connection point.
 
Re: Need some help! Double coil split

ok this cant be good, it appears ive wired everything up as per the diagram and ive created a kill switch in position 3? and everytime i change pickups it makes a loud POP, man this is annoying :(
 
Re: Need some help! Double coil split

well I got an email back from SD, and this is what they came up with:
sd.jpg


its almost the same as the hot version Artie drew up, only the red/white and black connectors are the wrong way around

im assuming this diagram wouldn't be humcancellin as you would need to reverse the pickup still

so if i reversed the neck pickup (not the magnet itself) would I be able to wire it up like this and still have it be humcancelling and all work dandy?
 
Re: Need some help! Double coil split

Since you're having some "functionality" issues with what you've done now, I would just wire it up exactly as SD tech has shown you. (It is the same thing I showed you, just they're switching hots, and I was switching ground.)

Do that just to get up and running, and see whether or not you have any problems with the noise-cancelling mode . . . or lack of same. If you don't, then problem solved. If you do, then we can make a slight "mod" rather than rewiring the whole guitar. ;)
 
Re: Need some help! Double coil split

yeah i wired it up in like the diagram i showed u just cos i thought id try em all to see which works better...this one gives me 3 working pickups, however its kinda weird, theres a lot of static noise (tho im not sure where this comes from, all my solder joints are done pretty well) and also, the middle selection (with the double coil tap) is very loud and my bridge pickup is hardly audible? i thought the double coil tap would be quieter than the other 2 pickups cos theyre running in parallel?

Art just so you know, they are NOT slang terms ... they are the magnetic polarities according to how the SD pups are made (Ant. series excluded) ...
I don't understand why questions that are explained and clearly labelled on the schematic (referring to mine) are being asked ... all one has to do is read and follow the schematic ... Plus he cut and pasted stuff from one of the schematics I gave him and reversed stuff (even though they were labelled bridge and neck {with arrows even}... I think he should take it to a tech.[/QUOTE]

Thanks Kent. Thats why I love this forum - learn new stuff everyday. ;)

As soon as I posted that, I got to wondering if that was correct or not. I really shouldn't post stuff like that to people who are asking, if I'm not 100% on something. :smack:
 
Re: Need some help! Double coil split

ok thanks for all the help Artie

u no i dont want to sound like an ass Kent but the only reason i ask so many questions is cos i actually WANT to understand how pickups work, im not one of those ppl who just put the pickups in without knowing why each wire goes where, so im sorry if i just wanted to learn

so fine ill take them to a tech who i already spoke to on the phone a few weeks ago who said it wasnt even possible, so im sure that would really beneficial

All the technical info you need is contained on the FAQ section of the main site, further info on the stew-mac site (under free info sheets), but when you post an image of *pieces*of one of the schematics that I did and
then reverse things, saying that the wrong coils are selected ... Ah, I don't
buy that. Everything was clearly marked on the diagrams.

Now, to use your line ... *I don't want to sound like an &^%*, but you asked how to wire it, not how to be taught how to wire it ... big difference.
That you learn by researching FAQ,free technical sheets, and books on the subject (and related subjects).

I do apologize for leaving off the drain/shield wires (hey Art I blame you for that, it was your art work I used ... :laugh2: ), those are understood to go to ground without exception,and aren't intergral to the design functioning correctly (as they are not coil wires), but they weren't on there, so hey ... no big deal now you know. Peace.
 
Re: Need some help! Double coil split

I have the same guitar with the same switch, but I am wiring up an EMG ZW set.
I know it's not related to Seymour Duncan, but I haven't found any other threads where they were discussing this type of switch.
Could anyone please make me a diagram how to hook up the cables to the switch? :)
