Any ideas why the attitude indicator is showing 10 degrees pitch up and a slight right roll in straight and level flight and on the ground? Things I have noticed, but may or may not be relevant: - Attitude indicator takes a long time to "wake up" on the ground. - During recent avionics install, several dry rotting vacuum lines were replaced behind the panel. - The suction gauge is indicating around 5.5" of vacuum pressure at cruise. The green arc on this gauge is around 4.5" and 5". - Directional gyro works better than before the line replacement. - The attitude indicator responds correctly to pitch and roll movements. It's just not centered in straight and level flight. - The last AI overhaul was in 2004 - Sigmatek 5000B-20 Besides replacing the AI and DG entirely with electronic instruments, what are the probable causes and solutions to these issues? Any recommendations for AI overhaul facilities?

Hello, I’m not so good at troubleshooting electrical stuff, so some simple steps to start before I hand off to my mechanic would be awesome... I have a JPI930, and it shows 13.0-13.3 volts pretty consistently. If I put any draw on the system, it sits at 13.0. I’m talking transmission, pitot heat, LED strobes, any one of those is noticeable. Generally sitting at ~3-4 amps as I don’t have much draw. Battery is new as of 2 months ago. PP alternator was new from last October annual. VR is Zeftronics R15300. To be honest, I’m pretty sure it was already doing this before the new alternator and battery... According to my limited knowledge and the battery instructions, I should see more like 13.8-14, no?
