I'm curious where people run their main cable from the battery to the
front of the plane. Through the tunnel? That seems like a pain and I
would have to drill some holes in the spar carrythrough or risk interferen
ce with the pitch push tube, plus route around the other things in there
like fuel and brake lines etc. I have some conduits run from the back up
the sides of the fuselage but I have a lot of stuff to run through them
and that is a fat cable coming from the battery.

I ran mine up the left sidewall where it would penetrate the firewall
near the relay. Most of the =9Csensitive=9D wires are on the
right side wall.

As you point out, the tunnel gets busy. The wires I have in the tunnel are limited
to the few things that make such runs convenient:
- Three antennas (comm #1 & #2 and transponder). The comm antennas are mounted
on the bottom of the tunnel, one on each side. This provides plenty of clearance
to the push tube and allows easy access. Transponder is under the passenger
seat. (Side note: ADS-B antenna is mounted aft of the baggage compartment
along with the ADS-B receiver, connecting wire is in a side conduit. VOR/ILS
antenna is in the right wingtip).
- Fuel pump.
- Audio lines to all four headsets.
- Flap wires.
- Both stick grip wires.
- Red cube wires.
Everything else is in conduit, three on each side of the plane. I ended up filling
up five of the six conduit runs. If memory serves the #2 welding cable going
from the two Master Solenoids mounded at the batteries go up to the starter
solenoid on the left side. Both battery ground wires go up the right side.
As most of us end up with a lot of stuff aft, more conduit is better than not
enough.

I would keep wires not called for by the plans out of the tunnel as much as
possible. I only have transponder (near front of tunnel), fuel pump wires
in the tunnel. This is a metal airframe. Absolutely zero need for a ground
wire from batteries to panel. The only ground wires needed for noise
reduction are those between panel mount items, audio panel and central
grounding tabs on firewall. Any item that draws more than a couple amps is
better grounded through the airframe. You don't have to believe me, that is
summary of discussions on the Aero-Electric forum.
You have enough wires fore and aft for positive power, com antennas, ADS-B,
autopilot servo(s), nav lights, strobes, etc.

Up the left side per the Electrical Kit plans.
I didn't buy the Electrical kit (most don't) but the plans for it are
very useful in terms of wire routing and discovering some parts (custom
cable supports and such) that are available from Vans. My electrical
system looks nothing like that supported by the kit but some of the
parts and particularly the fat cable route to the firewall are very
useful in many designs.

| Subject: | Oil in air filter box |
Hi all, I am just in the last stages of ground testing before first flight. I have
a new IO-540 from Vans and have run it somewhere between 1 and 2 hours for
run-ups and taxi tests.
After each engine run I have found a little oil inside the throttle body, some
on the alternate air door, and some which appears to have been blown out the gap
between the filter box and its support plate. That implies the oil finds its
way into the filter box during running or priming.
Has anyone else seen this and know if it is normal during the first hours of break-in?
I have called Lycoming and they dont have a magic explanation, other than
preservation oil still making its way out of the engine. That seems unlikely
to me, so Im looking for altrenative explanations.
Cheers

I am guessing they're right on with it just being preservative oil.
I'd think it should end after a couple flights.

I put my EarthX ETX 900 on the engine side of the firewall. I have a 43 poun
d prop with spinner so weight and balance will likely work out fine. I did t
he computations using Vans factory aircraft as a starting point and it was c
lose to a wash. I ran my starter cable back down the left side of the BPE oi
l pan and up and over the engine mount using adel clamps on the engine mount
. The battery weighs about 5 pounds and the battery cable will be about 18
=9D long. The starter cable is the longest. The Battery is on the lower r
ight side of the firewall. Yes it is more expensive, but it is a lot lighter
and I saved several pounds of #2 cable. They also last much longer and the d
ischarge rate while parked is close to insignificant.
