GRT Avionics

I am getting a "EFIS VOLTAGE BUS 2 TOO LOW"

Yet everything seems normal and I can't find any indication to support that announcement. Anyone see this?

GRT is likely at sun n fun. I would ask:
Is bus 2 hooked up?
At what voltge level is the alarm set for?
What does the efis say the voltage is (you can have it displayed as a bar on engine page)?
These questions would narrow down the search.
