Fellow listers,



I need to steal some more ideas for wiring in and around the engine.  I am concerned about routing the wiring and keeping it from flopping around.  I'm thinking a bunch of Adel clamps - but where/how attached/etc,



I have starter, alternators (both field and bus), CHTs, EGTs, oilpress, oiltemp, fuelpress, sparkplugs, and more....



Pointers to web sites or pictures (off-list) of what you did, how you like it, how well it works for maintenance would be greatly appreciated.

Personally, I used Adel clamps for only heavy wire (starter, etc.) and larger bundles of smaller wiring.  Routing a couple of spark plug leads or a couple of instrument leads, I use the double tie wrap attachment (one around the wires and anchor point and one between).  



Couple of things to consider.  Try to keep fuel, oil and instrument leads separated/segregated.  Keep electrical power and fuel separated at all costs.  Don't forget to allow for movement of the engine in its mounts.  Be aware of abrasion at firewall and other penetrations.  Don't let the leads rub on anything if possible, especially something metal or abrasive.  The vibration will eventually wear through the insulation.  Keep a little slack for future maintenance (spark plug leads loose enough to actually remove).  Keep them away from heat as much as possible or use heat shields and/or insulation.



Keep your routing neat and clean.  Don't have wires routing all over the place.  Try to follow the steel engine mount tubing when possible.  This will help you when you're trying to reach inside and do maintenance down the road.



Finally, ask yourself "what if" very often.  What if this wire is pulled, kinked, rubbed, pinched?  What if the cowling rubs on it when installed, will this linkage rub or pinch.  You get the picture.  Do it right the first time and you'll have a very reliable, safe machine for a long time.



I learned most of my techniques from an old A&P friend.  I'm sure there are other methods that others will share.  Sorry, don't have any pics available.



my 2 cents

Ralph,



I have a power-point that I down loaded from the FAA?  It's overkill but

very informative.



I send you a copy . . . If anyone else would like a copy send me an email

off line.



Good Luck,

Generally speaking, what I found worked best was two Adel clamps attached to each other at each attach point.  One goes around the nearest engine mount tube and the other grips the wire(s), tubing or whatever.  Worked well for me.  In the few locations that I used nylon wire ties I first slipped a short piece of split hose over the engine mount tube to prevent abrasion.

That is a very interesting document.



One thing to be careful of, if you find it useful - download it now.   

Don't assume that it will always be available at that URL.  The FAA  

periodically revamps their web site organization, and the URLs get  

changed.

You may have seen this, but you can downloand a pdf of it off the web . . .

probably easier to deal with.
