Hello, I have soldered a onoff shim to the header pins of a pi zero. The problem I have is that there maybe a short somewhere but I don’t know where. I know this because the led will stay on dim the whole time the pi is powered. When the pi is booted up, the shutdown is immediately initiated following by a blinking led on the shim. After the power has been cut off to the pi, the red led is also off.
Could this be a faulty board? I can’t find any shorts caused by soldering. How can I possibly solve this?
I can measue continuity across the button terminals. Maybe a broken button?
