I'm wiring my first Pico Crumble and as soon as I plug it in, the switch LED lights up, then the main LED shortly after. I don't have the button pressed. When I do press the button, the LED on the switch goes out, but the main LED stays lit. I thought that I had a short across the negative battery terminal to the first main LED light, but I've removed it. When I touch the negative battery wire back to the terminal on the card, it does the same thing.

Does anyone have an idea what I can look for to get the card to work as it's supposed to?

Thanks.
