Tonight I finished a few small tasks and powered up the panel for the first time. No smoke or popping sounds, and everything worked exactly as expected. This felt like a significant milestone in the airplane’s life.
The prep tasks included plugging in the few remaining items (CO detector, battery, OAT), and double-checking all the wiring. I had developed a checklist to follow to ensure I didn’t miss anything critical. Then it was time to power up the ground power module, and hit the Battery switch. Note, the panel doesn’t have a Master switch, as the alternator is switched independently. (Typically the Battery plus Alternator switches make up the Master switch.)
The “thunk” of the battery contactor closing, and subsequent coming-to-life of screens and switches was awesome. Plugging in my headset and hearing the crisp and clear audio intercom and radio transmissions of aircraft was exciting and rewarding. Mostly I felt relieved that everything worked as expected, so I can move forward with tidying up the wiring and checking the various subsystems (lighting, engine monitoring, autopilot etc).
