Pickup wiring problems

[JimmyM]

I try to install a set of pickups, and as usual with my wiring projects, nothing works. But this time, I'm bound and determined to get it working on my own without taking it to my luthier. So I shall turn to you all for help.

Here's the parts:
DiMarzio Model P
DiMarzio Model J
Stacked 500K pot, of which each pot in the stack will be a volume for each pickup
Existing 500K tone pot
The wiring diagram supplied is for two separate pots instead of a stack pot, V/V/T. I'm trying to wire the stacked pot as a V/V.

Now the tone pot is wired correctly according to the diagram, with nothing on leg 1, the capacitor wired to leg 2 and the back of the pot, and leg 3 wired to the tip of the output jack with the ground for the bridge to the ground of the jack.

So each pickup has 4 wires, black, white, red and green. The directions say to wire the white and black wires on each pickup together. I did that without incident. The red wire from each pickup is supposed to go to leg 2 of each pot. The green wire of each pickup is wired to the back of each pot. I wired each green to its corresponding pot in the stack. Leg 1 of each volume pot should be wired together, then run to leg 3 of the tone pot.

I did all this, and I got nothing. So is there something about this stacked pot that I don't know that I should be doing differently from the two separate pots? I'd really appreciate some help with this since I'd like to use this bass this weekend. Thanks!

Stacked pots are similar to non stacked pots when it comes to wiring.
You should check closely if your wiring match this one, or if you've got a short circuit somewhere (with a lead that touch a ground when you close the electronics compartiment), or else if you have wired the jack correctly.

Never got to it yesterday. But I'm starting to think that maybe I shorted out the stacked pots together because everything should work. My father has a voltage meter and he'll be able to tell me later today when I go visit him. Thanks!

OK, I give up. I got the thing wired and I thought I had it perfectly, but as soon as I installed it, I broke two solders, and even after I fixed them, I still have a noise, even though it's all grounded properly (yes, even to the bridge). And the tone control doesn't work. So I gave up and contacted Bayou Cables about building me a harness. Apparently I'm a lousy solderer, but I think I can at least solder pickups to a pre-built wiring harness.

I have never been able to solder. I don't know why I keep trying. All I do is burn my fingers and frustrate myself. So I give up. I will never solder again. For all the money I spent and time it cost me trying to be a do-it-yourselfer, I should have saved myself the aggravation.

Were you using a blend pot instead of a stacked volume pot?
They may look the same but a blend pot (also stacked) uses a center detent position. I'm wanting to do the same thing except to add a dpdt switch in the hole of the missing v2 pot to go series/parallel. This way it's either parallel with both pups at the same level no matter the volume or in series and the second pot in the stack is bypassed and it won't matter what position it's at. This way, one volume, a switch, and one tone. I'm mainly goin to do this to a short scale SX using original pups cuz one pup hummimg drives me nuts. I currently have Dimarzio no-hummers in but want to use them for another bass, and the Audere jz3 won't fit in this.
Now, I just need to find a stacked pot. They're not that easy to come by.
