Need help finding diagram - Half out of phase 2 single coils

[chumpy36]

Hi all,

I must not be using search right or this diagram is as rare as my last request. 

I have a mosrite copy with 2 p-90s and 3 way gibson style toggle switch. 

The p90's are three conductor (white is + red is ground and sleeve)

I want to wire them up where a push push switch (up) puts the two pickups half out of phase when in the middle position. Everything is normal with push push down.

I've found the original Bill Lawrence diagram and another diagram that I think can be modified but I don't really know how to translate the blade switch wiring to toggle. 

I'd also like to incorporate 50's wiring in there as well. Can someone help me modify these?

Thanks!

So, do you mean that the red wire has a braided shield wire around it? If so, the phase switch will create issues if the shield and red conductor meet at the baseplate or cover of the pickup. You can check this with a multimeter- check for continuity between the pickup's baseplate and the red wire- it should show an open circuit, infinite resistance. Do the same for the cover to red wire, it also should not show continuity.

If that's not what you meant, then I'm not envisioning this pickup.

Well, everything can indeed be normal with the switch down. But with the switch up, you will not get an effect only with the toggle in the center position- whichever pickup you attach to the phase switch will be bled through the capacitor when that pickup is selected by itself. The two pickups will be out-of-phase (and with one coil through the cap) with the 3-way toggle in the center position. But with the switch set to the pickup that has the phase switch, with the switch "up", you'll have that pickup alone through the cap. Not a deal-breaker by any means- who knows, you might find you like that additional tone. But just a "head's up" so you don't get something you're not expecting.

Sorry, bad wording.... I meant there is a white wire which is positive. A red wire that is ground and a bare silver wire.

See pic.

I think I can live with that. If I can't I'll wire it back "normal" 

Biggest issue remains I don't know how to translate the 3 way blade diagram into a toggle diagram. 

Thanks!

The wiring to the toggle switch doesn't really change from what it is now. Think of the "half-Phase" switch as a separate module that you will be inserting into the existing wiring. Two wires from the pickup go into the switch, two wires come out. The wires coming out of the switch go to the same places the pickup wires go now- one is grounded, the other goes to the 3-way switch. The whole module just gets inserted between the pickup and the 3-way switch. BL's diagram shows white and black wires, you have a red for the other connection (his black wire), but other than that it's the same as his diagram.

First, you need to decide which pickup, bridge or neck, to which you will add the phase switch. If it was a straight phase switch, without the cap, it wouldn't matter which pickup you chose, it would sound the same either way. But in your case, the cap does make a difference, both when you are in the center OOP position, and also when you are using the pickup with the phase switch alone, as I said above. I've never done the "half out-of-phase" thing, but putting it on the bridge pup would be my thought. YMMV.
