I have everything from #10 wire to #22 wire running in a large bundle on the left (pilot’s) side of the canopy. On the other side of the canopy, I have some smaller (#20 & #22) wires running with the coax cables for the radio and the transponder. On my first plane, I placed the breakers for most circuits on a small panel next to the co-pilot’s right leg on the wall of the cockpit. This kept a lot of the wiring in the cockpit that didn’t actually need to go to the instrument panel and precluded a lot of wires being bundled together for long distances.  In the new plane, the circuit breakers are all on the instrument panel and ALL wiring must go to the panel. I did not realize when I planned it this way that as much wiring would be required and that inductance would become a problem. I suspect that there is a lot of "carry over" from the coax cables to wires because of the way the gauges jump when I key the mike?
I am the first to admit that this is not my field of expertise, but I do feel that there is surely a way to deal with this problem in such a way that the inductance will not be a problem. I know that sometimes the simplest things seem to solve problems like how we used to twist TV antennae ribbon cable to eliminate some kinds of interference. For right now, I have purchased some shielded wire to replace the normal wire to see if that will help.  I am going to try running the wires straight through the cockpit without bundling them or putting them in the conduit to see if the problem still exists. If the problem no longer exists, that will give me a benchmark from which to judge any other arrangements.		 I am mentioning this now so that any of you that are wiring your plane can consider these things now instead of after the fact and maybe together we can figure this thing out.
I am indeed asking for help with this matter. If there is anyone reading this that is really up on electrical circuitry that can give me some advice on how to deal with this problem I would be very grateful for the help. For now, I feel that all the wiring that can be kept in the lower cockpit should be kept there. There is certainly no reason for the wiring for the gear retract system to have to go to the instrument panel. Small panels can be installed in various places that are accessible in the lower cockpit for most switches and circuit breakers, especially those that carry high loads such as landing lights, large primary power wires, and hydraulic pump wiring. One place for such a panel is just forward of the control stick built up slightly from the floor or just forward of the flap handle in the same location.
Always keep in mind that all switches and circuit breakers MUST be easily and readily accessible without contorting yourself and with your right hand on the control stick at all times. It is very easy to compromise your judgment for what you know in your heart is a less than acceptable location for switches and selectors and other kinds of controls. That is EXACTLY what killed John Denver. Don’t accept a half ass’d solution. Keep thinking until you get it right.

Think "Outside the Box"
HUH???
OK then, Just "THINK"!
FUEL TANK SELECTION
My comment in the previous paragraph about John Denver reminded me of the ongoing discussion concerning fuel selection in the Glass Goose.
If for no other reason, what happened to John Denver makes this a very serious subject, and I simply cannot abide individuals that have absolutely NO qualifications giving advice to other unsuspecting builders on what is safe and what is best to use as a fuel selection device on the Glass Goose or an		 other airplane. Some individuals have the ability to talk a good game and make it seem like they know what they are talking about to the otherwise uninformed. Unfortunately, most home builders are not professionals and are therefore hungry for information and advice when it comes to their projects and ill advised advice can really be detrimental to such builders, especially when they themselves have less than a professional attitude toward what they are doing.
