Cozy Construction Chapters.
Chapter 22 - Electrical system
Started 10/12/2011 finished xx/xx/xxxx Hours worked this chapter :69
Note that electrical for the engine is on that page. This page will show only inside electrical work.
Layout of SkyView HDX 10" touch interface from Dynon.
Power panel from Composite Design
IP with Power panel, left of panel is WIG/WAG landing lights switch, Constant Speed Propeller control, Engine Start/Stop, and Nose Landing Gear controls.
First Power Up test of the Panel as you can see with the landing gear indicator.
The back of the IP during the build
In the picture you can see some of the wire management I'm using.
Nose gear wiring rough in to pin out checking wire colors to engineering specs.
Completed nose gear wired, on the left you can see the black box containing the auto lowering circuit connected to the pitot tube.
Upgraded to LED landing lights in the nose. 3 time the lumen, consuming 1/3 watts.
The lights will be covered the Plexiglas covers.
The light a 4 X 9 heat sink, I don't have the room. So I created a hear sink radiator for each light.
Nose down test of landing light.
Nose up test of landing light
One hour later testing the heat sink, working great....
The inside all UV protect with the engine controls in place.
Note the two black knobs one for each fuel tank, also the red knob in the seat back center.
This is the plans spot for the fuel selector valve but I change that to two ball valves at the back near the fire wall not much of the fuel line running inside the cockpit.
Military Style Stick Grips from Infinity Aerospace, wired for speed brake, com radio and more.
In this picture you can see the wiring coming into the cockpit and the fuel valves, heat duct work.
Battery and Master Solenoid, you can also see the firewall pass through for +/- connection.
I've added the fuel tanks, marker light with strobs.
I put a top on the engine stand made from the engine create, giving me a Mobil work table
I needed to control my speed brake linear actuator using SPDT relays.
The question was how to change the polarity of the DC motor in the linear actuator with two joy sticks switches without a chance of a short.
Here is a the test build before I broke out the two relays from the six.
Co-Pilot side relays for speed brake (fully redundant pilot)
Pilot side relays for speed brake (fully redundant on co-pilot side)
Smart battery charge for LiFe smart battery from Aerovoltz they are real supportive and helpful.
First charge using the smart charger on the smart battery. you can see the three cables connection, the middle one on the battery is for diagnostics used to balance the 16 cells.
Finished charge with all cells now balanced.
More work ahead...
