The speedometer and RPM function normally. The indicating instruments are “zeroed”, not indicating anything. The battery discharge light is illuminated though charging system is actually functioning normally. Whether coincidence or not (I think NOT) the air conditioning on-off switch stopped working also. This is not steppers as my 43 years as an airplane mechanic rule out a coincidental failure of 5-6 stepper motors at the same instant. I’m thinking ground, body module. If it’s a fuse I can’t find it…
