I spent the morning tying in different items to the switches and ground buss. Specifically, I tied-in the strobes, navs, landing, taxi lights and the heated pitot. I then tested them. All worked fantastic. I removed the EXP Bus when Carlos arrived so that he could add the 3 diodes to the board for the BBAT circuit. I basically was a helper for a portion of the day. Cleanup and then home. Long day.
