Thanks Hawkeye for the suggestion
The crazy thing is I have a total of two different B747-400 that use the default panel and I am only having problems with the one. Now if that is not wired I don't know what is.
The cab file is in the panel folder I have tried copying the panel folder from the other aircraft but no luck I have noticed that in the other aircraft and the default when you first bring them up cold & dark the altitude gauge has a red green flag in it that I do not see in the problem aircraft. I plan on trying to use a panel from a airbus that I have and see what happens if the same gauges do not work than something is rotten in Denmark.
I have checked to make sure that the Avionics and battery are both on and they appear to be as I see other gauges come alive when I turn on the Avionics. Like you I am thinking it has something to do with the needle or how it gets its input so to speak. I really have not looked into to deeply as I am trying to finish a around the world tour for a Virtual Airline I just joined I am on my last leg. I should finish this when I get home from work.
I will let you know what I find out.
