Hello! Not sure this is the right place to post this. Disclaimer I am not good with electronics but I decided to take on a reef-pi project. My background is in IT but never worked with anything electrical unless you count UPS in server rooms.
I am following the adafruit power controller guide and I am stuck on trying to tune the LM2596. I am trying to use the power supply that I have with the barrel jack connector to power the LM2596 so I can step it down before connecting to the protohat.
The problem I have is the power supply won't power on the converter. DCV testing with multimeter shows that I get 12V at the barrel jack connector as well as the leads. But when I connect the leads to input + and - on the LM2596 I get almost 0 volts at the barrel jack connector and at the leads. It is like the power supply stops working once the converter is connected.
Any help appreciated. Even if there is a different or better way to do this. Heres the adafruit guide.

reef-pi Guide 2: Power Controller
This guide will walk through the build process of controlling AC equipment using an automated power strip (power controller). The power controller allows scheduled and on-demand control. Power controllers are simple and inexpensive to build and it acts as a foundational layer for temperature or...
