Thanks Pete I have a nose gear. So the level attitude both on the ground and in flight is about the same. I did change the ground when I rewired the acft. But I changed it in my trouble shooting procedures. Now I have not checked the power supply to the gauge. I might put a temp wire from say the ignition switch straight to the gauge. That is about the last thing that I have not done that I can think of.
