Hi everybody, I’m new to the list (I unsubscribed 3 yrs ago after I finished my 7A) and am working on a 10 (#871) here in Independence, OR.  I know a few of you here, like Vern Smithand Rob Hickman.  I’ve got some questions.  After an early failure of a Tefzel engine ground cable on my 7A, I replaced both cables coming off the battery with #2 welding cable, which I have been very happy with.  I plan on utilizing it on the 10 as well.  I based my wiring in the 7A on Nuckolls (Aeroelectric Connection) wiring schematic (roughly z-11), on my 7A, including the “forest of ground tabs”, which I’ve also been very pleased with.  My 7A has no hums, pops or crackles in my intercom and no electric gremlins have made themselves known yet in 3 years of flying.  I love my Sirius music setup!  In reviewing Van’s wiring plans for the 10, I see that the ground cable from the battery is attached to the airframe near the battery box.  Is everyone utilizing single point grounding for all the accessories(?) and if so, where are you mounting those single point grounds and what are you grounding there or not grounding there?  And most importantly, are you picking up hums/pops or voodoo transients from strobes etc?  I have none of that in my 7A and am hopeful I’m smart enough to wire the 10 so its electrical system is as (electrically) clean as my other plane.  Suggestions??   If anyone has photos or diagrams, feel free to load me up with them offline.  The other question I have is whether anyone has a wiring diagram that incorporates a G900 system.  I’d like some ideas on how it’s wired before I cover up some critical areas.  Although I’m a pro at drilling out rivets, I just don’t dig it…

Bob, I don't think there is one way that everyone is doing it.

I think that people either ground locally, or ground up on

the forest of tabs, and it's all their personal choice.

I know people have good luck both ways, but avionics aren't

standardized among us, so no way to know what overall will

be required for you to have a noise free system.  I myself

pulled a welding cable ground all the way to the forest of

tabs up front.  No noise.  But, that's not the only, or

the "right" way necessarily.

I'll be running a separate ground cable from the battery, through the 
	


firewall, and to the engine. From the firewall feed-through I'll run a 

ground cable to the sub-panel where all my ground wires will terminate. 

It's the 'ease of cranking' goal, and avoidance of gremlins you're wary 

of. Poor grounds can really make a bald spot on your head as you scratch 

while you try to trace down that gremlin!!! 



Certified aircraft save money and weight by grounding to the frame, and 

I've had some limited problems with that route over the years.

Welcome!  As a some others have done, I ran a separate #2 welding cable all the way up to the firewall and used a bolt as a pass through and single point ground.  I’ll ground my forest of tabs and the engine directly to that point.  It also serves as the airframe ground via the pass through bolt for any far flung devices like the led nav lights.

My preference is to run a ground wire out to the extremities instead of 

using airframe ground. Current flow along with a little moisture and the 

connection points will start to corrode where you have dissimilar 

metals. Spraying the airframe ground connection points with something 

like Boeshield cuts down on the moisture problem, but it won't go away 

entirely. Your maintenance time down the road should be a consideration.

Thanks for the input.  I went with my original decision to pull both a power

and ground cable up to the firewall and attach the ground to a ground tab

and carry through bolt.  I bought the first piece of #2 welding cable at

NAPA and paid $3.50 per foot, but they didn't have red, only black.  I did a

quick search online and found that Northern Arizona Wind & Sun has black or

red #2 welding cable available for online purchase

(http://store.solar-electric.com/hardware---wire.html) at $1.97 per foot, so

even with shipping it's much cheaper than NAPA.  Their phone number is 800

383-0195.

Bob,

You may want to consider the modification that William Curtis did for 

routing the power cable through the FWF.  If I had not already drilled 

the hole through the FWF I would have done it his way.  He used a feed 

through connector.  you can see it here:

Home Depot also sells #2 Welding cable. 50 feet for $67.97.  THat's $1.35 

per foot!

Search for part #: KH567 or SKU 615771 on their site.

Just remember that in case of fire, that welding cable insulation will 

probably emit rather noxious fumes. 

I know, it won't stop me either  , but then I've never had an 

inflight fire to worry about!!!

Yes, I'm sure that's true.  As a former welder, I know how hard it is to

ignite welding cable, since it's designed to be showered with hot drops of

metal and sparks in its normal work environment...but if you work at it, it

will ignite, though I have observed that it has great self-extinguishing

properties.  I am sure burning Tefzel insulation is not much better to

breath in a closed environment.  Best to keep our wires from burning in the

first place, especially the fat ones directly connected to an energy source

as large as a battery.
