groundrepairwire
I just bought a new turntable and receiver
When I began using it, I noticed there was a loud buzzing sound coming from it.
Looking at the turntable's cables, there are the two Left and Right RCA cables as well as another cable with a missing head (not sure what the proper word is).
I realized this must be the ground cable and it just has uninsulated wire coming out of it.
Can I buy a new ground "head" and reattach it? How do I do this? Thanks
You can replace just the threshold. Sometimes it is difficult because the original threshold is screwed to the jambs as part of a complete assembly, or it lies under the door stop part of the jambs, but it sounds like you already figured that part out.
I would caution you to investigate and fix whatever caused the water penetration (in case there was an additional issue besides the old threshold) and repair any damaged wood underneath before you install it. I assume your new one is aluminum since you mention filling it with spray foam, screw it down well with stainless screws.The screws that come with them are not always the best ones to use.
Sounds like you have your switch leg ( switch loop ) mixed up. You need to isolate it. It is the wire going to the switch. A simple continuity test will determine which wire is the switch leg. You need a continuity tester and most voltage testers check continuity. As for the ground, there is none available unless you provide a new circuit to the panel assuming it is grounded correctly. Since there is no ground you can remove the fixture ground to avoid any potential problems and to save space.
Here is an example drawing I made (Revision 2):

A crimp on eyelet or forked spade connector should do. There's nothing particular about a turntable ground wire like there might be for an antenna wire. I'd probably cut off the damaged end, re-strip with the appropriate size tool, and crimp to fresh wire. A locking pliers (Vice-Grip) works will in a pinch. So to speak.
It's also possible that the wire never had a connector. Some grounding lugs are designed to take a bare wire. Simply wrap the wire once around the lug, under any washer that's present, and snug it down lightly.
