Your G12 control panel is the power distribution center for the
coach. This panel receives the signals sent from your switch
panels and performs the actions that have been requested by
activating and deactivating the required circuits.
Every circuit controlled by the G12 is numbered and listed on
a black label (load list) which is usually mounted next to the
G12 panel. Troubleshooting Example - If you press the Front
Accent Lights button on your
Lyra screen and the lights don’t
come on, check the Network Diagnostics Page to see if the
light for Output 27 shows status. If it does, you will want to
check output voltage on that pin to make sure that the G12 is
sending power to the lights (Fig 1).
