4hrs
Didn't get as much done as I wanted. Have wrist injury that prevents serious use of the left hand. I guess there is such a thing as too many push ups. Riveting is out of the question, so just spent today on cleanup tasks.
Placed orders with Spruce, Stein, and B&C, picking up items that Wayne and I need.
Took a bunch of photos of the wiring and avionics, recording serial numbers, etc. And I have pictures to refer to after the skin is on.

Measured a few more items. The 430W draws 1.83 Amps on the low power input, based on how busy the screen and computer are. It was a bit less at startup. The high current supply is at nearly 0 most of the time, then draws 4.7A at transmit.
The Facet fuel pump draws 1.4A. This is an expensive but neccesary endurance bus load. The panel leds only draw 20mA.

So this is all good info for using the ebus for it's intended purpose - endurance. Assuming a fully charged 16AH PC680 battery, with the xpndr, audio panel, #2 radio, and autopilot, all drawing about 1.8A, (with occasional bursts of trim), I have an endurance of about 8 hrs, more than enough to outlast fuel, or the 1 hr battery life of the Skyviews. In fact, I should consider moving one of the Skyviews to the Ebus.

Also did some final wire bundling, removing switches from the panel so that it can be removed.

For Friday March 5, 2 hrs
Finished up checking all the fuse values. Also measured current draw for a few of the ebus systems. Install transponder antenna and fired up the transponder for the first time.
Finally put the 327 up for sale. It was time to let go. I really wanted to use it, but the Trig/Dynon xpndr took away its job.
