No signal unless the input is plugged halfway in?

Hey guys,
This is a question about my guitar, but I'm not on any guitar forums and I think some of you may be able to help.

I switched out the pickups in my Les Paul. Everything seems to be wired up correctly (I'm not a pro, but I've done this a few times) but I'm getting no signal, EXCEPT when the input jack is plugged halfway in. Then it works fine!

I've checked the connections on the input jack itself, and they're solid. None of the other connections seem loose or weird. The only difference is that the guitar originally had a pickup with 2 leads, and I replaced it with a newer one with 5.

Both pickups are now wired: green & ground to the top of the volume pot, red & white taped off together, black connected to the pole on the pot.

Originally, the old pickup with 2 leads was wired: black to the top of the volume pot, white to the pole on the same pot. I didn't change anything else.

Any advice is very much appreciated! I don't know anything about electronics, so I'm just working by trying to copy schematics that work.

 

Nope its for sure connecting at the jack. I only took it out to check after it already wasn't working.

 

Oh wow! I had no idea that different brands had different colours. I'm gonna try a different combo using this chart, thanks so much!!

 

Ahh, gotcha. Pretty darn sure it's fine though! Looks perfect when I take it out.

 

Dang, no luck yet. I've tried a bunch of these different combinations and no matter what I do, I'm still only getting sound when the cable is halfway in!

 

The wires are connected properly inside the jack. This guitar was working properly before I swapped the pickups, and I didn't touch the jack wiring at all.

 

Woah I've never heard of a stereo jack! This is just a regular mono one. It's wired properly though, at least on the jack side. This guitar worked fine before I swapped the pickups, and I didn't touch any wiring other than the pickups.

 

I know, it sure does seems like it should be a jack problem, but I'm looking at the jack right now and it's working perfectly! I've tried a couple different patch cables so it's not that either. The cavity isn't shielded, but the jack isn't touching anything either. I'm tearing my hair out!

 

I don't have one, unfortunately. Never needed one before... I wouldn't really know how to use one anyhow.
