What’s happening with my Fender Jazz?

[okabass]

Tonecap wire touches to pot case (ground)? Not good soldering joints. Are the many pot washers necessary? They may make the pot case grounding bad. Put a solder dip between the copper seams: make a sure contact between them. Put a copper strip from the cavity shield under one control plate screw. Check the wiring. If it is a normal JB the white wires are hot, and black are ground (Check for ex. the neck PU's wires).
If that comes on my worktable, I'd take it apart, and make it like it was at the factory.

Reverse the leads on the neck pickup, and while you're at it put a jumper in from the back of the vol to the back of the others. Practice you soldering skills first.

Thanks... will try.

Just so I’m on the same page...
Change leads on bridge = change pos on black and white...?
(Just a remark... changed the cables due to a brutal phase problem)...but maybe I did something wrong then.

Jumper = small bits of cable that runs between pots?
Back of the pots?... where’s that?
On one of those three small dohickies that’s attached to the pots?

Forgive me for my extreme noobi-skills and comments.

Q. Change leads on bridge = change pos on black and white...?
A. Yes that.

Q. Jumper = small bits of cable that runs between pots?
A. Yes,

Q. Back of the pots?... where’s that?
A. That is where the white lead you are going to move is presently located.

Please note that she said to reverse the leads for the neck pickup not the bridge pickup. Of course, that would be obvious if you compared the schematics provided to your pictures.

Thank you. I missed that in the little Q & A session.

Of course neck... I was thinking neck but wrote bridge. I think I had too much soldering vapour in my nose.

OP needs a hotter soldering iron. I'm seeing lots of goopy, mechanically suspect solder joints. A hotter iron and some heatshrink tubing will make for tidier wiring.
