YB-4 Wiring Issue

[pharms]

What I mean is testing the ground connection on the volume pots. I'd probably start with the ground wire between the tone pot and the volume pot considering that both volume pots are not working. If that connection is ok then I'd be checking that the tab on each volume pot has a solid connection to the ground via the back of the pot.

Here is an isolated kit pot where I'm testing that the tab is properly connected to the back of the pot. The tab is soldered directly instead of using a wire but that doesn't matter.



Without a ground connected properly, the volume pots won't bleed off the signal to ground. This explains how a volume pots works.

Thanks for this. I will give it a shot.

I just read this again and realised I may have misinterpreted. So you don't have any volume at all now?

Correct. When I soldered the jack directly to each volume pot/pick up, the pot worked. However, when I soldered all of the connections per the diagram, 2 volume, 1 tone, I get no sound from the pick up. Woltz provided some info to test each pot. I will give that a shot then start to replace wiring if required. Thanks for your help!

Good idea. That would likely reduce the usefulness of flux, but both wouldn't hurt.

Of course, these tips assume the OP's fault is with the earth solder ...

Thanks for your help.
