Today was a great day.

1. With my friend Jim, we powered-up the electrical system for the first time. At first, only the units on the Main bus were getting power. I was able to power up the Essential bus also, using the "E-Bus Battery Direct" switch, and everything powered up fine. Several LRUs did not seem to be connected, namely the transponder and roll servo. After putting in some basic configuration information, the transponder connected.

2. We also successfully tested the Smoke system relay/wiring and the Pitot Heat relay/wiring.

3. After some troubleshooting, we figured out the Schottky diode between the Main and Essential buses was installed backwards. After flipping it around, it worked fine.

4. We tested both sets of pilot jacks by plugging in headsets to each, using the intercom, and successfully receiving transmissions on Com1.

5. I configured Com2 in the Setup menu, and it too received transmissions.

6. Next, we began to track down why the roll servo was not showing up on the CANBUS device list. First, we removed the wing connector and ran 5 jumper wires between the connectors, but this resulted in a short somewhere that popped the autopilot breaker. Next, we opened up both wing connectors and found that the power and ground appeared to be swapped. We got the leads corrected, but the autopilot servo was still not coming up. More investigation is necessary.
