Hi, I'm making my control panel right now, and would like to wire it up. I would like the mimic panel to be able to light (LEDs) via battery power when the transformer is unplugged. I have prepared a schematic but I am unsure if it will work and don't want to blow anything. The reason that i am unsure is because I have commoned the battery and the 12v transformer supplies. Could someone please check the schematic which should be attached to this message.
