Hello All,
I've been lurking on this list for some time and come to the conclusion that I have little interest in diving into the electrical design and issues for my Rocket as deeply as is addressed here. My hat is off to all of you and I am very glad this forum exists as I truly believe you are accomplishing good things in advancing the technology for aircraft. But this subject makes my head hurt.
I have lurked enough to form some opinions on what I would like incorporated into my aircraft. I am now looking for a more simple way of drawing this out so that I can "connect wire from point A to point B". Anyone have any ideas ??

Assuming your Rocket is a simple VFR airplane i would choose the simplest of Bob's Aerolectric schematics and copy that. You really can't go wrong.
If you have anything fancy like twin electronic ignitons or IFR then you need to be careful and make sure you have redundancy built into the design.
But if you have two mags, mechanical fuel pump, radio,transponder. Then simply make sure you have a seperate circuit for each device that is fused appropriately.
I would use the alternate feed method so that if you have to shut down the the master switch (in flight fire) you can at least call for help on the radio.

I started my original electrical system schematics with pencil, paper
and an eraser. A very big eraser. Select Bob's Z Drawing that
matches your needs and draw it out, putting the wire size and wire ID
on each wire. That takes care of the big picture, which gets power
to each bus. Then, make a separate drawing for each system, starting
at the bus, going to the fuse (or CB), then to the switch and then to
the item(s) that need power in that system.
While it is certainly possible to draw the schematics with pencil and
paper, I found that I made too many mistakes, and you can only erase
one area on the page so many times then you need to start over. So,
I switched to a simple drawing program on my computer. I used
AppleWorks on my Mac, but there are many other programs that will
work on all modern operating systems.
It isn't difficult, but it is time consuming.

Two things, Larry:
1. Get Bob Nuckolls' book, "The Aeroelectric Connection" and read it. Then, take a look at the various wiring diagrams included in the appendices and pick the one that best suits your aircraft.
2. Attend one of Bob's regional weekend seminars.
This will solve most of your simple "how to" questions. The remainder can be asked here and you will get expert answers.
Best Regards,
Steve

Larry, you can learn how to use one of the flowcharting/design tools on a computer and make your own design.
I thought about that and realized every minute spent learning something like that would time away from flying. So, I bought Bob's book, made copies of the schematics supporting features I wanted and used some tape and scissors and made my own. I wired the plane and it all works. I am a retired banker and not an EE or mechanic. You can do it using Bob's schematics..

Thank all for the replies on and off list. Two good points were made that have me beginning slow progress: 1) paper, pencil, and a big eraser; and 2) separate circuits onto separate sheets of paper. I saw this on Randy Pflanzler's web site and it made bite-size pieces. I suppose I can render these pencil drawings to CAD later if I wish.
