My guitar's bridge humbucker keeps failing

[alessandroarzilli]

Hello everyone! My guitar's bridge humbucker keeps failing, it's the second time I have to solder it.
What am I doing wrong?
I'm not using any coiltapping or phase switching technique, just the black wire to the switch and the green + bare wires to the back of the pot.
After some days it sounds "deaf", until I unsolder/solder those wires again and everything returns perfect.
Duncan Solars 7 string (neck + bridge in Jackson JS227)

Do you have any parts that may be accidentally grounding out on other parts?

Next time you have it open, take a few pics. We might be able to spot something.

My only thought would be to completely clean then scratch up the lugs and wires a little bit to rough up the surfaces then press them tighter together before soldering over that, if it’s indeed a connection problem. But if it’s the grounding out issue, you need to troubleshoot that a different way.

Does the sound go away suddenly? Or gradually? Are you standing, leaning or doing something in particular at the moment sound goes away?

Is it possible your pickup switch sometimes cuts out?

Hello everyone and sorry for the late answer.
First of al, thanks a lot for answerring me so quickly.
I'm having my guitar right in front of me now, back cavity open, I'm taking some pictures.
I'm also recording with Reaper right now, so the neck pickup works fine, the switch's middle postition (both pickups) works fine (but I doubt it's getting the neck pickup only), the bridge pickup doesn't work.
I'm gently touching the cavity's wires while playing one string and it seems like I didn't wrap up the bridge pickup's red and white wires enough well.
What do you suggest me to do?

EDIT:
I think I solved the mystery, those red and white wires from the bridge pickup weren't wrapped enough, I could hear crackles when moving them. Here's how it sounds, you hear neck pickup first, then both, the the bridge pickup. Is it okay, now? https://www.dropbox.com/s/7fuhbljuy7v24bh/JS22-7 PICKUP TEST.wav?dl=0

You have to solder the red and white together and then wrap them, not just wrap them.

Re: My guitar's bridge humbucker keeps failing

Well, I've done that before. I've even thought 'I will solder those at the end' and then forgot. And nothing works the way it should.
