Tele grounding issue

Hey team

I've made a partscaster tele with my extra quaranTime, and I very clearly have a grounding issue. Whenever I touch the strings, or anything metal (bridge, knobs, etc.), I get a huge jump in noise. Moreover, there is TONS of noise with even a little bit of gain present. The pickups work – other than a hideous amount of noise, the axe sounds as it should when I play.

It's set up with a double humbucker configuration, each with a Duncan Triple Shot mounting ring. I have a 3-way LP style toggle switch, a volume, and a tone knob.

I have everything star-grounded to the volume pot, including the bridge and pickup selector switch. I'm POSITIVE that the bridge is grounded. I pulled it off TWICE to check that there was enough exposed wire under the bridge to make contact. I tried swapping the hot/ground wires coming from the triple shots to the pickup selector with, no change. The input jack is definitely grounded appropriately to the volume pot. When all that didn't work, I placed a screw into the body inside the control cavity and sent a wire from the star-grounded volume pot to the screw. No difference.

I'm not sure what's going on here. What am I missing? Why isn't my new baby ground properly?
 
Re: Tele grounding issue

A jump in noise when touching parts makes me think something is wired backwards or not wired at all. My first guess would be the bare wire from the pickups is not grounded maybe.

Need clear pics though.

Also, do you have a multimeter? Your eyes can’t tell you if something is securely connected, but a multimeter can!

Yes, does sound like the ground is in fact on the hot end.

A multimeter is a great tool here. I had a switch/tone circuit issue recently where I was not getting continuity even though the solder joints looked ok. Once I tested continuity through every connection, I found where the issue was and had working tone pots afterwards.

Yea, the trusty multimeter helped me find a cold solder joint that looked ok at first.

Thanks everyone!
