Duncan wiring codes over time

[ItsaBass]

Hello,

I am installing an older version of the PG (PGBL), and I see that the wiring codes might be a bit different. Black and green are connected (instead of red and white), while the bare ground wire is wrapped around the white wire (instead of green). Is this just how a previous owner wired it, or did the color codes used to be different than they are now?

Thanks.

IDK if the color codes were different but I do know that the diagrams are different than they are now, they called for a .022 cap and not the .047 called for now. That's on a dual him, 2 tone, 2 vol w/3way switch. I know I used to have an old diagram from some pickups back in the 80's, I'll have to see if I still have it.

Maybe it was installed to be split to the screw coil.

++1 That's the way I do my splits. Wire the neck as yours is. That allows the "split" connection on both pups to go to ground to get bridge-slug/neck-screw. Makes the wiring a smidgen easier.

I don't know. The bare wire being around the white wire looks stock. And I wired it up as it is, and the pickups are not out out phase in the middle switch position.

Have Duncan always used the same wiring code?

The idea of the wiring you seem to have is that you can split to the screw without it being oop with other stock wired duncans. The other method (simply flipping the black and green) will cause oop issues.

To clarify, the way it is set up, red is hot, white/bare is ground, and green and black are connected (no coil split).

I'm pretty sure I understand what you're saying, but correct me if I am wrong: Basically, as it is, the pickup should be expected to play nice and in phase with the other one, because both sets of wires have been flipped, not just one. This was probably done at some point in the past because the previous owner wanted the screw coil alone, not the slug coil alone. Is that correct?

Yes

This might be a good place for pic.



In the top figure, you ground the "middle" connection for split-to-stud. In the bottom figure, you ground the middle for split-to-screw.

It actually sounds to me like someone wired it up like a DiMarzio.
