I installed the Dynon screen to the left, the two G3X EFIS screens and the GTN 750. I then hooked up the battery without master switch and noted no smoke or arcing. I then turned on the master switch and the Dynon and two G3X screens came alive. SO COOL! I then turned on the master switch and the GTN came alive. COOL AGAIN! Everything needs to be calibrated, but the screens work. I then turned on the taxi lights and they worked. The Nav lights worked however I inadvertently placed the green nav light on the left wing and the red nav light on the right wing. I switched these around. Also a stuck mic key message came on the GTN 750. By placing the headset jacks into their sockets the stuck mic key message disappeared.
