Dimarzio Wiring Problem

[richardsim7]

So I've rewired my JS1200 with updated satch pups, but I'm still getting the weird grounding hum problem. When I touch a pot I get a weird crackling sound unless I'm physically grounding the guitar using my finger (or pinch the bridge ground wire). Where is it going wrong?!

Hello Richard:
I notice no response.
I didn't see a ground to the 3Way switch housing.
Also I would experiment with the bypass cap on the vol.
I would take it loose to see if that changes anything.
Also I recently wired a customers guitar with 2 DPDT switches.
I used one for split, and the other one for Reverse Phase.
Worked slick.
You have 2 nice switches there but not utilizing them too much.
Make sure you have a real good ground between all the pots and switches.
Good Luck,
Rock On!
Terry

Ya know that might just be it! Be right back

Nope, nevermind

Oh well, I've ordered new pots and I"m gonna resolder the entire thing...

You sound pretty handy with a soldering iron, and test gear.
Did you take a ohm meter and read from the sleeve side of the jack to each component ground?
Also make sure the bridge ground reads low ohms.
Later,

* Edit Note:
Here's another wiring Diagram for a comparison.
It uses Seymour colors, you may have to sub your colors.
I've always had great luck with SD wiring diagrams.

So I got new pots and rewired the whole thing from scratch, the problem still persists but it has MUCH improved...
