"strat" pickup wiring help needed

[johnnymegabyte]

I have an 1982 Ibanez Blazer Custom (strat) that had all pickups changed to Seymour Duncans about 10 years ago.
Well, for the last 6 months the middle pickup has been acting up, which is wired to a phase switch, and I think the switch is toast, or maybe the SD pickup.

Last week, I found this wiring diagram online, so I attempted changing the middle PUP to the original Ibanez single coil last night, but major BUZZ. I know I did something wrong.

If you see the diagram for the phase switch, where are the 6 connectors
1-2 (2=white)
3-4 (3 to 5 way switch, 4=bare wire, and connects to tone pot)
5-6 (6=red)
1 connects to 6, and 2 connects to 5 (like an X)


I am thinking, bypass the phase switch, and wire it to the volume & 5 way.
But, what wire goes where ? Red = Pos, White = Neg, Bare = ground.

Any help would be appreciated.

To the best of my knowledge, the way the switch works is to connect the middle terminal on each side to either the top or the bottom pole, depending on how the switch is turned. Turn the switch up, and run a little jumper wire between the top two poles on each side (in your numbering, I believe this connects 1 to 3, and 2 to 4). As far as I can tell, that should do the same thing the switch does in the "up" position. If you get no sound, try the switch in the other position, as I may have the operation backwards. If this has no effect on the hum, the switch isn't the trouble.

typical me ... soldering idiot. I tried that ... not working. Probably my fault.
and now I did something as the neck pup isn't working, probably broke a connection putting the pickguard & electronics into the guitar.
Should just pay the price and get it done at the guitar shop ... and done right.

No big deal either way, man. If you're not comfortable messing with it, there's certainly no shame it taking it to somebody who is. I just paid somebody to fix my computer for that reason.

When I'm trying to figure out a wiring scheme, I typically don't solder anything until I've verified that it works like I think it does; I just twist wires and tape a little bit, then check. Seems like it makes less mess in the (inevitable) case of mistakes.

If you happen to have a digital camera, it also doesn't hurt to get in the habit of taking a picture of the wiring whenever you have the pickguard off, for comparison purposes later -- if you broke something, it'll be that much easier to pick out.

I'll accept defeat on this one.

Actually, I plug in the guitar electronics while out of the guitar body, and tap the pickups with a screwdriver, one-at-a-time and changing the postion on the 5-way. Loud plink and no buzz means it's working. I won't put it back in the guitar without going through this test. Problem, I think is when I put the electronics back inside, wires break or contacts come loose.

I've done that recently. But for this guitar, I drew all the electronics and wiring on a sheet of paper, with color indicators, roughly 10 years ago.
