I guess what the thread starter means is that the transfer bus remains failed after the NNC (half of the overhead panel lights ON
) .
What I would do is check the checklists at least and apply some common sense on which checklists to do. That way you have an idea which systems you have left. IMO it is one of the most tricky failures on the 737.
PS: A nasty result of a transfer bus 2 failure is that the flap indicator does not work anymore. Some crews mistakenly see this as flaps not working anymore... Amber bar on PFD still shows correctly and will move when flaps come out.
