Electrical system, VPX and GTN 650 initial power up: 4 hours

Powered on full electrical system including both batteries and VPX. After that I connected the G3X and GTN-650 and powered it all on with no problems :)

  • Made and installed wiring from main feed fuse to VPX - used 6 awg wire
  • Figured out wire routing for main feed and contactor wiring and secured temporarily with wire ties - this will be done with cushion clamps when the inverted oil system is installed
  • Wired main, auxiliary and start contactors
  • Wired start contactor annunciator which included soldering a resistor near the ring terminal
  • Temporarily connected both batteries and powered on system using the instrument panel battery switches.
  • Downloaded VPX windows configurator program and connected to VPX with ethernet cable. I then uploaded my initial configuration to the VPX. I also did some basic system checking but I believe that the G3X needs to be configured before going much further.

All avionics powered on - time to configure:
