View Full Version : Electrical Wiring
I am designing the wiring for my Air Command. Does anyone have a wiring diagram they can post here? Specifically I would like to know how you've set up the master switch, if you have additional switches for avionics (radio, fuel gauge), etc. Are you using the frame of the gyro for ground, or are you running ground wires from a bus? What kind of wires are you using, and what kind of connectors (engine disconnects, etc).
Or anyone else that cares for that matter...
I 've noticed that people NOT in the know think wiring up any kind of flying vehicle is childs play compared to building or flyiing them...and I know I USED to think that.....
But having followed rec.aviation.homebuilt and related forums for years I've learned there is NOTHING trivial about anything having to do with wiring up a flying machine..
Apparently there are VERY correct and VERY incorrect ways of doing virtually EVERY little task related to even very simple electrical wiring in an aviation setting....
Now, I cant remember any details...but apparently its like gyro flight physics....lots of "theories" and the way its "really" done by the pro's....
So much caution and research are called for here...
And in the spirit of Chuck ..anybody who "cant handle the truth " can pound salt :)
Good Luck Udi :)
I think if you do a web search for Jim Weir? you might find some good online articles on practical/safe wiring practices

Yeah, Jim Weir may be the most well known 'lectrics guy around. And that is because he writes for Kit Planes!
It also states at the end of his articles that he is the chief avioniker (whatever that is!) at RST Engineering. His web site is listed as www.rst-engr.com/kitplanes where his previous articles and supplements can be found.
I believe he has also covered antennas and other devices as well as wiring. Apparently he answers questions posted in an Internet newsgroup called rec.aviation.homebuilt.
The best publication available for aircraft wiring (and aircraft electrics in general) is available at:
I personally think this guy might know more than Weir- at least in the aircraft arena. The book covers wire selection, switches, relays, contactors, alternators and generators, proper grounding, power regulation, fusing and breakers, various sensors, antenna selection and hookup, and more than I can list here. It starts out assuming the reader knows nothing about DC electronics and it progresses through common aircraft setups.
It also supplies several complete schematics and diagrams for common aircraft applications (including those suitable for our less complex jobs and those suitable for more complex applications).
The book is designed for the homebuilder. Bill Clem tipped me off to this book several years ago; I donít believe there is a better book available. I'm just about done wiring my ship and the reference was invaluable.
Rob, are you almost done with your Dominator? Did you run the engine already? When are you planning to test fly it?

udi this site help me a lot many pdf explaining connections
Udi, Iím hoping to finish for Mentone, but weíll see. I started the engine about two months ago. It seems the SDS fuel injection and spark control are going to work well. I want to get some more dual before I get to the point of serious testing.
How is your Air Command project coming along?
I'm almost done! Other than electrical wiring, I have a bunch of little things to finish, and I'm done. This project turned out much more complex than I was led to believe, but I am almost through.
