As above. I have a 4 way switch and a push/pull pot. I just need help finding the schematic for it. Anyone with a road sign? PLease

amtaylor- Courtesy of our own sumgai, here's a std schematic for a Tele 4-way switch, as used on the Baja Tele. I assume this is what you want out of the 4-way switch.  The phase switch on the push/pull is a separate module. It should be placed on the bridge pup in this 4-way scheme because the bridge pup forms the "base" of the series chain (one end is permanently grounded. (You could do it on the neck as well, but that would mean some reworking of the diagram. It's just easier on the bridge with sg's diagram, and which pup is put out of phase doesn't matter.) It goes between the pup and the 4-way switch. The module looks like this:  If you're unsure about any of this, you can draw up a diagram incorporating both elements and we'll vet it for you. It's a good idea to translate the schematic of the 4-way to a wiring diagram before soldering it up in any event. |

Cheers. I don't suppose there is a wiring diagram about as it's been ages since I did any wiring and I'm not certain which pins refer to which bit of the schematic. I really should sit down and work it out but I'm moving house and a bit swamped so anything that could make it a bit easier would help.

Don't know that we've got a diagram for that specifically. I'll hunt around a bit to see what there is. I can draw one for you but it wouldn't be until the weekend at best.

Oh one thing. It seems the positive of the neck pickup needs to go to ground on this circuit. I can't quite seem to work out why but is that correct. And then the cover is grounded seperately? Is it right that I only need to ground the volume pot? I'm star grounding. I'm not sure if this will make any difference but I figured why not.

There are multiple errors on that diagram. The tip of the output jack is connected to ground and the sleeve is connected to the wiper of the volume pot. That's bass-awkward. There are two wires from the bridge pickup going into the phase switch, but only one wire coming out. That's not gonna work! If the pots are drawn as viewed from the front side, the tone control will work in reverse. If they are drawn as viewed from the rear side, the volume control will work in reverse. Not sure what's supposed to be happening with that 4way, but it doesn't look like any 4way Tele wiring I've ever seen. It seems like the ground connections are poorly labeled and inconsistent. Maybe that thing makes sense to someone else, but I can't figure out how anyone could work from that and end up with anything but a nightmare. |

I'm at work, so I couldn't vet the diagram, but if RT says it's NFG, then it is.
Regardless of what diagram you end up using, if you're going to do series connections with a Tele neck pickup, you may need to unground the neck pickup cover, if it's not a separate ground from the pup windings.
You would then run a separate ground wire from the cover to the shielding, or to the bridge ground or other grounding point.

Yes, that diagram looks right.
I was wrong about the direction of the pots on the first one, but other than that it was messed up.

That's a bummer about the switch, man.
Both drawings are correct and they're drawn as if you have the control plate upside-down and you're looking at the bottom of things. If you compare them, the wiring goes to the same lugs, but the lugs are shifted.
The lugs are shifted because the switches came from two different manufacturers.

Yeah I would have nearly finished my tele build. All apart from setup. I've decided to go without the phase switch now as its not meant to be brill with tele pickups anyway. I'm gonna keep the pot for another build methinks. Gotta wait until at leas tuesday now and I'm moving house over wednesday and thursday so won't get much time now! Stupid switch! Thanks for the help
