Mine is a very simple installation, with
just a
couple of MGL Stratomaster instruments, a radio, transponder and GPS.
So, the wiring isn't that much of a challenge - so I thought. I started
off by buying the Aircraft Electrics 101 DVD, which more than paid for
itself as I learned heaps. I continued the adventure by drawing a basic
wiring diagram in PowerPoint to get myself organised and make sure all
would work properly. (The schematic does not include the ignition
circuits, which are explained very clearly on the plans.) I then ran
this past a couple of avionics gurus in the Air Force - some good
feedback ensured I was well on the right track. So after that, I
ordered my electrics stuff from Aircraft Spruce.
The Stratomaster maxi singles (FLT-II and E-I) have quite a few sensor
wires, so I decided to install a terminal strip to keep everything
organised. I also bought a good pair of ratchet crimpers and a good
wire stripper - well worth it. Then, it was into the wiring. As I write
this, I have yet to finish, but am well on the way to getting there. I
decided earlier on to do the electrics before installing the tank and
glare shield, to make it easier to get to the wiring runs and have good
access behind the panel. I also took the engine off to gain good access
to the firewall.
The schematics call for a master solenoid that can be isolated should
you have a run away starter. I bought a really good continuous duty one
from a local dealer in Canberra. I also went one gauge thicker on all
the wires - probably not necessary, but it gives me a warm and fuzzy. I
also bought a 100V 10000uf capacitor to take out electrical noise
between the battery and regulator. Adrian Clout recommended this one,
he has the same in his Sonex. Just for grins, I've also included a
photo of my knee pad. My good buddy in Colorado Springs had this made
for me in Korea, with my rego, name and a picture of the Sonex - pretty
neat huh?
