Hello,
I'm following the exact procedure but I'm always facing a warning on the MCP before starting the engines. Always it displays the Following in yellow: ELEC BACKUP SYS . although everything is configured correctly, the message doesn't go away unless I start my engines. attached is the screenshot. your help is really appreciated in order to solve this error cause it seems that there's something wrong in the before startup procedure. [but the weird thing is that once the engine s are started the error / warning disappear
