Back from "vacation".

While on vacation, I took the Bauer book and an iPad with the Avidyne simulator.  I made it over half way through the book and will need to use the real IFD for the analog (VOR, ILS portions).  I connected a bench top power supply to the 12 volt buss and navigated the menus and panels for several hours.   I left the power supply connected to top off the EarthX battery.  I has a Battery Management System and isolates itself when its charged. 

I installed a USB socket on the panel for the Dynon memory sticks so I didn't have to tuck them in behind the panel.  Several times I flew without the flash memory/charts because I'd forgotten to plug the sticks in after updating the charts.  

The left brake was mushy.  Ultimately I found the park brake was starting to leak so removed it.  I was having a difficult time getting the brakes bled with a pneumatic powered bleeder.  It seemed like air was leaking into the piston of the master cylinder.  I had a couple on hand so swapped it and the low pressure line out.  Still not getting a real solid pedal on either side, I put 75 extra pounds on the canard and raised the nose up about a foot.  The next morning, the pedals seemed to pump up pretty good so need to taxi test to be sure they're working optimally.  

I pushed the Cozy out to taxi test and the master/essential buss relays wouldn't operate.  The fault LED on the EarthX was dimly lit (as usual).  The fault light is usually on because there's a little bit of leakage through the indicator wire out of the EarthX that connects to the EMS.  There wasn't an apparent reason why the battery should have died.  None of the panel switches to pick up the master or essential buss relays were on.  I tried to charge the battery, but zero amps would flow.  The voltage across the posts was 1.7.  A call to EarthX support was on a Friday afternoon right at about mass exodus time.   The tech had me try a few things and then asked if I wouldn't mind calling back on Monday.

Vance had left a wimpy PC680 battery, so I threw it on the charger over night.  It's float voltage was a little over 12 volts.  I had to tweak things a little to get the PC680 installed and connected, but it didn't have any trouble cranking and starting the engine.  

Skyview warned the database was out of date, so that was updated.

There was a hint of blue (fuel) dye on the inside, forward bottom cowl below the fuel pressure sensor.  Running the pump for 5 minutes with the cowl off didn't produce any wet fuel or odor. 

We had a significant storm and the air has been rather turbulent, so hopefully I can get these squawks addressed and make some flights.
