Thanks for the input on this guys. I remain open to what you are saying, but indulge my hard headedness for a minute longer. I readily admit that I will quickly forget details of my electrical system in the near future. However.....
It seems to me that the wiring diagrams chief benefit is for mulling things over from the convenience of your own living room. If I start messing with my electrical system its likely to be because something isnt working, and this will require me to gain access to the various components of the electrical system. The hidden components of my electrical system (AHRS box , fuseholders, wig-wag flasher, voltage regulator, etc) are relatively easily accessible and if any of these are not easily identified by looks alone, they are labeled. Every wire coming from such components is labeled with respect to exactly where it is coming from and where it is going to. Therefore, I will be able to check that the electrical connections are sound at both ends of every wire segment. I will also be able to check that the wires go to the right connection point on each component by comparing my connections with what is presented in the manufacturer's documentation, which I have carefully cataloged in my building binders. I can further check that components are actually connected as labeled with a continuity tester.
In short, it seems to me that most of the truly valuable information on my electrical system can be gained from the schematic and when necessary for repairs, visual inspection/testing of the individual components and at their electrical connection points. The actual route the wires take between components seems almost irrelevant to me.
I am not terribly persuaded by arguments of some perceived future value to future buyers of my plane. First, Im not sure I buy the argument that my plane will be worth less. The phrase "Comprehensive wiring diagrams available" doesnt seem to show up much in adds for experimentals. And for those buyers that have the desire/need to know my electrical system, I still think the schematic and good labelling practices I have adhered to, along with manufacturers' documentation provide a solid basis for diagnosing and resolving problems.
Okay, I can already see the aero-electric masses collectively shaking their heads back and forth at me. Nomex flame suit donned. Fire away. Concrete examples of how your wiring diagrams saved the day, and conversely, how my annotated Z-13/8 schematic and comprehensive component and wire labeling are woefully inadequate will be enthusiastically received.
Just between us girls, I'll bet there are more than a few out there with virtually no electrical documentation combined with complete ignorance of their system. They may even be conspiring to sell these planes to others! : ) [quote][b]

Erich,
I can see both sides of this issue and they are both right. Roll your own. I am going the simplified route myself. I like the Z-11 as a basic and I have added a few extras.
I am amazed though at the detail some folks put into their wire diagrams and web sites. You people are absolutely gifted. Where do you find the time to do all of that and build an airplane?
I don't think I will ever sell my airplane but if I did it seems these planes sell themselves.

I drew a wiring diagram first because I wouldn't know how to wire it if
I didn't (basically a Z-11). Every signal has a name, every wire is
labeled. As one who has successfully used automotive wiring diagrams
(and other schematics), I'm sure the diagram will save trouble shooting
time down the road. It will influence a future buyer IF the guy is like
me. A lot of us builders are nerd-geek-techies who think this stuff is
important.

No need for flamesuits, Erich. If your documentation does it for you,

more power to you. I seriously doubt most buyers would want to see a
wiring diagram any more than they'd want to see the plans the plane was
built from. The diagram is just a tool, not a holy document. But just
as I can drive a screw with a hammer, it 'nice' to have a screwdriver
for the job.
