2 HB dual coil cut master series parallel switch wiring advice!

Hey guys!
I generally don't post questions as I will do all my due diligence searching past posts as to not annoy anyone, but I have really been having a time of it trying to figure out this wiring.. Sorry if it is droning or all over the place.

HAVE:
2 humbuckers, 4 conductor Sh-1's (flipped mag on Bridge)
1 volume
1 tone
1 standard 3 way switch
Top drilling for 2 mini switches.

I want to be able to use:

Humbuckers in standard series
Bridge Hum
Neck Hum
Slug coils only
Screw coils only
Any of the separate coils

AND have a master/parallel switch for putting both pickups in series and in parallel when combined together, not in respect to each humbucker's own coils..


I have flipped the magnet in my bridge Sh-1 and repotted it, so the magnetic polarity would correct for proper humbucking when coil cutting to inner or outer coils, ala PRS or Ibanez....
t
Now I have read a lot of different things here in respect to magnet flips, and from what I understand I need to use the "inside out" wiring for the Bridge humbucker with magnet flipped, as described on the humbucker page at http://www.1728.org/guitar1b.htm and very well by Artie on this thread. https://forum.seymourduncan.com/sho...sues-when-reversing-the-magnet-of-a-humbucker..

If I want to use a on/off/on dpdt for inner coils/ humbucker/ outer coils.. And I have flipped one magnet, how do I wire it?

I seemed to remember some draw ups for a coil/hum/coil on/on/on switch in the past, and while I can't find them now. I am guessing I have to wire the wiring as "both north coils, humbucker, both south coils", seeing the bridge mag is flipped, however, I guess I will need to reverse the output wires also...



2nd issue is wiring the master/series parallel switch.

I have read the megabucker page, the stuff on guitarelectronics.com, 1728.org,..etc... But it seems that when both humbuckers (or split pickups) are set to run together in series, that their is a ground loop, or some sort of issue with ground, i'm guessing a ground loop?

If this is the case, can you some how wire a switch (dpdt 4pdt,etc..) that would lift one of the grounds when master series is turned on?
Or could you possibly just wire the ground lead from one pickup directly to the other one, daisy chaining the ground, and eliminating whatever issue this series/parralel switching can cause?

I have been trying to wrap my head around this for 3 days and i'm in a rut.
 
Re: 2 HB dual coil cut master series parallel switch wiring advice!

the master series/parallel switch isnt to big a deal, will use one switch and there shouldnt be any ground loop issues as long as you ground the bare wire for both pups. its not too wordy, im just not sure how to do what you want without sitting down and figuring it out. getting north/both/south coils selected on one switch is what im not sure of.

I'm guessing this would work, but I would have to reverse the + and - leads from the flipped magnet pickup?

i dont think you need to flip the wires but you do want to separate the bare wires and have them wired directly to ground, not the switch

Ok, I gotcha.

I had read in another post where you had to flip the sides of the wiring when you flip the magnet for phase issues, this was the diagram that Artie had drawn up at that time.

I have the package in an Es-175, so once it's all stuff back in, it's a real bear to fool with again. I think i am going to to make a mock board to hook everything up on in the future.




Thanks for your help Jeremy!
