So I am making a guitar from scratch and I just wired up some brand new pickups and stuff...it works but buzzes a lot, when I touch the bridge or the ground on the pots it stops buzzing. I guess that means the grounding is bad? I have all the wires connected properly (following a Dimarzio guide).

I am also confused with the pickup wiring. It has 4 wires...black(which I connected to pot as ground), green (which is my hot wire,connected to 3 way switch), red and white wire connected together (coil splitting, don't need it) and theres a bare wire which I guess is supposed to be ground, but if I connect it along the black wire everything just stops working. Thanks for the help.

It is a grounding issue for sure. Without a link to the wiring diagram u are using or maybe some pics it will be hard to diagnose. Black May be the ground but Black is not always the wire you ground on those pickups. For instance here is a diagram for one of my guitars with red running to the grounding terminal on the vol pot: http://www.dimarzio.com/sites/default/files/diagrams/RGT42mod3.pdf

Yes the bare wire will attach to whatever wire is the ground.

I had a similar issue. The volume pot terminal you wire all the grounds to (same terminal you run the jack ground to) needs to also be grounded to the body of the pot. Looking at the dimarzio diagrams it was hard to see. You can just solder one wire to the pot terminal and solder the other end to the actual chassis of the same pot, right on top of it. Here is a picture illustrating the ground: http://images.search.yahoo.com/images/view;_ylt=A2KJke6M6l9S_RIAXSeJzbkF;_ylu=X3oDMTFxcXIyazhsBHNlYwNzcgRzbGsDaW1nBG9pZAM5MDAwMjc0ZTFlNjgwMDAzMzk5NWJkMjJjOWY2NTM2NQRncG9zAzU-?back=http%3A%2F%2Fimages.search.yahoo.com%2Fsearch%2Fimages%3F_adv_prop%3Dimage%26va%3Dvolume%2Bpot%26fr%3Dyfp-hrtab-901%26tab%3Dorganic%26ri%3D5&w=220&h=200&imgurl=www.ratcliffe.co.za%2Farticles%2Fvolumepots%2Fbleed3.gif&rurl=http%3A%2F%2Fwww.ratcliffe.co.za%2Farticles%2Fvolumepot2.shtml&size=4.1KB&name=Normal+%3Cb%3Evolume+pot+%3C%2Fb%3Ewiring&p=volume+pot&oid=9000274e1e6800033995bd22c9f65365&fr2=&fr=yfp-hrtab-901&tt=Normal+%3Cb%3Evolume+pot+%3C%2Fb%3Ewiring&b=0&ni=21&no=5&ts=&tab=organic&sigr=11kh4kpec&sigb=13cusjvpc&sigi=11iao0p8b&.crumb=tCxhzxnYTks&fr=yfp-hrtab-901

I hope this helps. Good luck.

I did that and the noise is way less noticeable now...but still if I touch the input jack or potentiometer it gets even less noticeable...but it goes nuts if I touch the 3 way switch...I guess I have to connect the middle part of the switch to ground too?

Thanks for the help. Grounded the switch and now it's much better. There is still some very slight buzzing that goes away when I touch any hardware...any way to fix that too? Perhaps I need some insulation?

No on the insulation. Something still needs grounded. Did you ground all of the switch terminals that were not in use? That might help. Otherwise go back through all of ur ground connections and look for broken solder or cold solder joints. After that, I have no clue.
