So about a year ago, I built a Saga tele.
I decided it was time to upgrade it, so I ordered a pair of Lil Punchers from Guitarfetish, along with a couple DPDT pots for coil splitting.

Everything appears to be wired according to this diagram.

It might be noted that I bought a three-way switch from GFS as well, and I bent the terminals so that all of the terminals to be ground were on one side.

Also, whenever I touch the rails of one pickup, I get a REALLY bad buzzing, which can't be good.

Any help?
Main gear (For complete list, see profile):
Epiphone Les Paul Standard Plain-top
Basswood Telecaster, 2 single-sized HB's, both split.
Epiphone Valve Junior
B-52 AT-412 Cabinet
Oh, and I have a Squier VM Jazz Bass too.
Just sounds like either a wrong wire somewhere, or a couple of solder points arn't done properly, maybe your earth?
Just make sure all your solder bits are clean and that the wires are touching the lug/pit whatever, thats a common mistake that people make, solder isn't supposed to carry current so there must be some contact
