Innaccuracy of Dimarzio and Ibanez wiring diagrams (help!) - Page 2

It won't hurt it to try that...and occasionally color codes can change, though rarely. At NAMM, I was talking to the guys at Duncan, and they said they often mix up the colors at the factory. lol... They were so non-chalante about it... like "Yeah, it happens, but people figure it out..."

Try it the way your Jem is wired. If it's outta phase, reverse the colors that are grounded and sent to positive.

Somehow I doubt that the colors got m ixed at Dimarzio because both the
neck and the bridge pickups are wired the same.

I wish Ibanez had the 89 diagrams on their website, showing the correct switch. And the colors for that matter.

The colors aren't "mixed" per se. Each coil has an "in" and an "out". If you reverse one of the coils, the pickup is out of phase with itself, and the sound is stupid and it doesn't cancel hum. If you reverse both coils, its back to normal, but 180 degrees out of phase than before. Reversing the "inner" phase of the pickup and then reversing the "overall" phase can be a way of controlling which coil you get when the guitar is switched to single coil. You could reverse the phase of all of them, but with a middle single coil, or hum-cancelling single coil, often times that one is locked in, and so you can't. So to wire a humbucker, you have the in, the out, and the coil jumper. On a Dimarzio, you could have the white and black tied together with red hot and green ground, or the red and green together with black hot and white ground. Then you can reverse hot and ground if you need to reverse the phase. Its really an either/or situation.

And yes, the "Drunken Duncans" often mix up their colors. Its rare, but then so is spontaneous human combustion, and I don't like either.

Frank,

Perhaps that is what they did on the 89 Jem 777 then. Its interesting thou, because the diagrams from 94 and on (the only ones on Ibanez site) show DiMarzio's standard wiring scheme with:

RED: HOT
BLACK and WHITE: together
Green and BARE: ground

I wonder why they did the 89 differently? Isn't the single coil the same as the later models?

It should be the same single coil, but depending on which direction the hums were loaded in, their wiring might've been switched. If the baseplates were reversed, or the pickups didn't have a neck/bridge designation, then the right coil is really the wrong one if its turned around. And the PAF Pro looks the same either way. It's not screws on one side and poles on the other. Or maybe its just the way it was. Remember, when you switch the direction/phase, you're back to the same series wiring sound, and the Jem single coil could go either way, because its a simple single, not a stack, and it doesn't jump the ground to shield. Check it out, maybe the wires on your single are backwards, too.
