Posted: Tue Oct 02, 2007 8:06 am Post subject: battery cable routing

I've studied many of the contruction logs from the popular sites and

haven't seen much on the routing of the big battery cables.   I've seen

no real guidance in Van's instructions in the Finishing kit or the FF

kit.



So here's the basic question.  For those that have already done it,

have you run the 2 gauge battery cables through one of your flexible

conduits from behind the baggage compartment up into the sidewall above

the wing spar? or have you made other dedicated hole for the battery

cables and kept the conduits open for all the other wires?



Also,  is there a preferred side to land the battery cables on the

firewall?   On our other airplanes we have always landed the wires on

the pilot side, cause it made for the shortes run to the starter, 

However this plane seems to have the oil cooler taking up a lot of space

on that side.



Thoughts and pictures appreciated.

I have run them through conduit with the other wires on the pilots

side of the plane.



As for a preferred side, that would probably be the pilots side,

which is what the Van's electrical plans show.  That's because



* That's the side that the starter is on

* That's the side that the starter contactor is on

* That's the side that they have wire covers and things made for

	if you want to use them

* That's the side that the contactor is on the battery box.



And whatever other reasons.



You could do it on the other side if you wanted, but it'll

possibly mean some creative routing.  The oil cooler doesn't

interfere with the starter contactor at all.

Some of it is very dependent on your electrical system architecture and 

implementation.



eg.

1. Are you running a dual battery or dual alt system?

2. Where are you planning on placing the busses? If you put them on one 

side or the other of the subpanel, it will likely influence which side 

you run cable on.



I ran a #2 Battery to Starter contactor cable on the pilot side for the 

reasons Tim noted. I also ran a #4 cable on the left side for the main 

buss & a #10 for the Aux buss, as this is wher e I've located the fuse 

blocks for the busses.

Bob,



I originally intended a firewall mounted battery, so I closed up my

floorboards before I ran the cable.  I wish I hadn't.  The rear battery now

forces the cable up the right side to avoid going over the baggage door,

etc.  That added at least 3' of cable.



Go under the floorboards and up the left side.  I think there are provisions

to mount a contactor on the left side of the firewall above the oil cooler.

Plenty of room there for the cables.  The starter is on the left too, so you

don't have to cross over.



I put my contactor indoors, also closer to the APU plug tie-in.



The picture is from the tunnel looking left.  It would have been easy to

route the cable up the left side.  Doh.

Bob,



I've a bunch of pictures of the conduit routing on my website 



www.wellenzohn.net



It starts on in the bottom of the gallery No9

http://www.wellenzohn.net/Fuselage/index9.html



I routed three conduits to the front.

I'm doing a dual battery, dual alternator, split bus system.  For 

cabling, I'm following the lead of Van's basic electrical harness and 

running my #2 and my #6 guage together along the left side using exactly 

the route laid out in their installation instructions. 



I've tried to do  some careful planning and sizing and it looks like I 

can run all the wiring between front and back using snap bushings, cable 

clamps, edge grommets and the brackets included in Van's electrical 

harness kit (they can all be ordered separately).  I'm simply 

replicating the left side on the right side too.  Then I'm adding some 

conduit for unforseen future cable.



Now this is all planned but not all done yet.  The cables are going in 

this week or so.  So we'll see.



As many have said, the Van's kit is limited for many of the panels and 

systems we're installing, but a very good starting point nonetheless.  

Using the installation manual to guide my own custom setup seems like a 

very good way to go.

I ran mine from behind the baggage compartment up into the sidewall above 

the wing spar like you said.  Then it makes a bend inboard and down going 

under the pilot seat, under the forward floor board (under the pilot's 

feet), and up the hole right aft of the firewall.  Same on the right side 

for other wires.  This eliminates wires being visible around the NACA vent 

areas.

I'm curious why you would run the extra wires from the battery, Deems?

My TC aircraft has battery in same location, runs #2 to starter relay, 

where lead connects to same terminal to feed the main bus, and aux bus. 

The starter is only used when there should be absolute minimum draw on 

the buses, and not in use when you need power for all the other stuff. 

Just seems like extra wire and complexity, at first blush.

Kelly, the short answer is, .... I wasn't smart enough to think about 

doing it that way.

Honesty is admirable. I'm sure it won't make any difference in the long run. Doesn't look like I will be able to make LOE. Keeping fingers crossed at keeping schedule open for Copperstate.

Don't kid yourself....one look at his aircraft and and you'll see just how smart he is. How did it go with Mike on the transistion training Deems?
