Boot sound then nothing

[Darth Maggot]

Running off of a fully charged 18650. I have metered the switch it is a good momentary switch. No voltage coming from the board to the led and no sound coming from the speaker.

I found the problem. It is a prewired Nano Biscotte. The negative wire to the switch was not properly seated in the harness.
