Pardon my ignorance

No, I got my jack from my guitar teacher who had his EMG thing laying around. Any other suggestions?

You're supposed to use a stereo jack.  The 2 familiar lugs are the same as a regular mono install.  The 3rd stereo lug is for the black wire going to the negative pole of the battery.  The ground portion of the mono cable shaft makes continuity between the ground and negative battery pole when plugged in.

This is my wiring. If you see anything wrong, PLEASE PLEASE PLEASE let me know!!! I've been wiring for a week, and I'm starting to turn into a Diva. (and I've already eaten a snickers)

Do those have the hot lead surrounded by insulation and then the shield gets grounded to the pot?  If so, it looks like the shielded lead stops at the pot and I don't see the hot lead continue out through it to the toggle.  Those other white wires, if they are grounded to the pot and that's supposed to be your hot leads, they can't work if both ends are grounded.  For that config., 1 vol, 3-way toggle, the pickup leads terminate on the toggel not the pot.  Are those the EMG pots also?  If not, they need to be 25K.

My guess to why it is working when partially plugged in is that the tip is grounded and when partially out, the tip is going to the battery and the ground to ground.  The battery looks to be the least of your problems.

No, that's soldered right... :\\

I'm sorry to say the pictures made it worse for me, maybe because of the color code of the wires used.  If you use white for hot and white for ground you will get easily confused as I am right now.  I usually use white or black for hot, and use both if I am designating seperate stages in a circuit.  Ground is always recognized as a green wire to me.  Red makes a good designation of a battery +, or if you were using a true stereo output, red may be one of your hot leads.  These are just the typical color codes most wiring people recognize, but as long as you were consistent it wouldn't matter as much.  Either way, I can't see the big picture of what goes where. Did you ever draw a diagram for this, or I missed it?  The problem is definately in how your wires are connected to the jack, and possibly another mis-wire between the toggle and the path to the output from what you just described.  If I was in your shoes, I would use a continuity meter and trace out the hot path and make sure it goes through the toggle, switches properly, and gets to the proper terminal on the output.  I would also double check all of the grounds, and hots to make sure you are not grounding something that isn't supposed to be grounded.  And please don't use a continuity meter or ohms meter with the guitar battery hooked up. :icon_biggrin:

At a glance, I would say the jack is wired correctly.  In this instance, the white (hot) is the only one that has to be in the right place, and it is.  The 2 blacks are interchangeable as far as I'm concerned because they are both electrically continuous when the cord is plugged in.  FWIW, if that's the jack provided by EMG, it comes prewired.  What happens after the jack, that's another story.
