      Hey Folks,

      I’ve had my OSSC for a while, and never had any issues with it.

      Tested a bunch of fuses, and they all seemingly get continuity/power.

      Not sure what’s wrong with it, and looking for some advice on what I should check to see what’s wrong with it.

        I’m not sure if the switch is bad? I’m an electronics noob.

        When I test the output of the plug and switch while it’s off, I see that it’s getting 5 volts. When I turn it on, I’m no longer getting a reading on the switch.

          The switch has has three(!) pins: one input (middle pin) and two outputs (left/right pin). One of the outputs (the pin next to the border of the pcb) is not connected. So in the OFF position you should measure 5V on the middle pin of the switch and on the pin next to the border of the pcb. In the ON position you should measure 5V on the middle pin of the switch and on the other output pin!

          Please check your measurements and report, if there’s a different behaviour!
