hey
i have 2 questions, both of these relate to a 2 hum, 1 vol + 1 tone guitar with 'ultra' 5way switch wired for series/parallel, the problem being that the way it is currently wired means both pickups are active in all positions so i am trying to make it so it's position- 1bridge S - 2 bridge P - 3both S - 4neck P - 5neck S - if you see what i mean?
they're a matched set of bareknuckle nailbombs and (i think) the 4 wires are:- red - south start (hot) green - south end white north end black - north start (ground)
1) due to the way i've had to wire the switch to get it to do series/parallel both the hots (red) are wired together. the black and white are already grounded, if i ground the green too will it kill the hot of both pickups?
alternatively... 2) both the black and white are still grounded. if i where to mod the switch so that the green wasn't connected to anything but the red was still going to the hot would the pickup still sound?
the reason i want them fully separated is i am running 2 separate coil taps for each pickup but they only fully coil tap if i have both coil taps activated (which defeats the point of having 2 independent switches)
many thanks in advance, sorry if i've been a bit vague i can supply any additional info if needed

Jaz-
Hello and Welcome to G-Nutz2!
You are correct that we will need some additional information.
First, I don't know what an "ultra" switch is, in terms of your 5-way. Fender makes a 4P5T Superswitch™, and Schaller makes a 4P5T Megaswitch™; these are not identical. Is yours perhaps one of these, or is it literally called an "ultra" switch, in which case it is perhaps something else again?
We have to know the switch logic (how it works) before we can tell you how to wire it.
Also, if you can diagram how you have the guitar wired at present it will help us see what you're looking at. I think I know, from your verbal description, what you have now, but a picture, as they say, is worth 1000 . . .
Also, if we're going to talk about specific wire colors, we need to move beyond "I think" in terms of what the colors actually are. I assume the Bareknuckles website has this info, we can go have a look for that to confirm this once we get to the point of a specific rewiring scheme.
I mention this because you said:
If the black and white represented both ends of one of the coils, grounding both ends wouldn't give you any output from that coil. This leads me to suspect either the correctness of your designation of the wire colors, or of your statement that both are grounded.

OK, I see now what we're dealing with here. The blue "nubs" coming off of your 5-way switch- do those all go to ground?

Jaz- Sort of in parallel with this thread, we have recently had this one: Please help me wire!Which links to a DiMarzio diagram similar to what you want insofar as it has N and B in series and in parallel. The third , middle position of the DM diagram has a middle pickup, so I liberally borrowed stole from the DiMarzio diagram and came up with this: The blue wires/connections for position 3 are the ones that I added. Now, this has the middle switch position giving you the N + B, that is, in parallel rather than in series as you stated. Each pickup is in internal series, but the 2 pickups are combined in parallel, not series. This, of course, is the standard Les Paul way of doing 2 HBs (and also with most other 2 HB guitars). But if you really want the middle switch position to give you both pickups combined in series, I can't see how to do that with this scheme. The problem is that to make a series connection you have to elevate the ground end of one coil. This scheme already uses all 4 poles of the 5-way Superswitch, so there isn't one to spare for position 3 on the switch, to elevate that ground. Notice that one end of each pickup is permanently connected to ground- the black wires from each one goes to the pot shell. In order to put both pickups together in series, one of those black wires would need to have its own pole on the 5-way. But, again, you don't have one to spare, and I can't see how to simplify the wiring of positions 1,2,4,5 so as to salvage a pole. So I think that a parallel connection in the middle is the best you can do without more switching. Now, there is also the question of whether my diagram is right. And maybe there is a way to do series in the middle and I'm just not seeing it. So, sit tight before firing up the iron.

hey, that diagram looks promising are the colours for the wires relevant for the dimarzios or have you converted them to match the bareknuckles?
with my regards to my diagram, yes all the blue nubs are going to ground, i just didn't draw in all the extra lines to save it getting too busy

I converted the wire colors to the Bareknuckle colors, as per your posting. But, again, let's let someone double check that I did so correctly! Of course, this also doesn't show your other switching, so you'll need to translate a bit; when it says "neck white", for example, it will if fact be a wire coming from the other switch, but I think you get that idea . . . The key question again is: Can you live with the two in parallel at position #3?

i've had another look over the diagram you posted and should the white and green not be the other way round? the way yours is wired for the pickups in parallel mode it would have both ends of one coil grounded and both ends of the other coil live but surely you need one end of each coil live and the other grounded? also you say about having bother pickups in parallel in position 3 (which is fine by me) if i hade the bridge pickup with the phase invert on would that make them series or not? i've been pondering it for ages but i don't know quite enough about it to come to conclusion

OK, let me double check the wire colors again, I'm at work at the moment so can't do it now.
Inverting the phase does not change a parallel connection to a series one, you will just have parallel out-of-phase ("POOP").

ahh ok. no rush on checking the wire colours either as i'm not looking to do anything about it for a few more days

Just a quick check, but my diagram is definitely NFG. positio #2, in particular, is bad, and the re may be other problems as well. Let me have another go at it, hopefully more successfully . . .
