I just tried shoving my BYOC confidence boost into a 1590a enclosure. Its a tight fit but i got stuff in there. I went to fire it up and a couple weird things happened. When the power supply is in, but there is no chord in the input the LED lights up very bright. When i put a chord in, the LED weakened and looked as if it was dying. When playing in bypass, signal flows fine and there is sound (some static but i know its just a crappy connection on one of my solder spots). When engaged, nothing. Weak LED and no sound. Any one ever encountered this? What should i do? It worked fine before i tried wiring it with led and such.
Read about debugging in the FAQ and the thread at the top of the page.
Every single person on the board has had a build that did not produce sound. There is no one thing that causes this.
Things to check...
Solder joints
All ground points have continuity with ground?
Have a limiting resistor for the LED?
V+ shorting to ground?
Bypass wired right?
Etc...etc...etc..
. Its a tight fit but i got stuff in there.
Clue #1...

Clue #2
....sounds like a big voltage drop causes the LED to dim when the input cables input sleeve makes contact with the Gnd./Sleeve lugs of the jack, completing a short circuit.
I would prefer the LED be switched with everything elses power at the input jack, but in this case it seems to be a way of reading voltage input and then voltage drop.
Tight fit/ stuff in there, very dim LED...perhaps there's a shorted PS, remove the battery and test for continuity between V+ and Gnd. [beep mode of DMM].
