[aprssig] 12V wiring ideas

I also neglected to mention that the Jeep was hit broadside by a very large
pickup truck.  Damages were around $10,000 to the Jeep after all was said
and done.  The Power Poles remained connected.  (The other guy was at fault,
and his insurance paid to repair the Jeep).  Between that, the jarring you
can experience during rock crawling, and some of the back "roads" it has
been on, they stay connected.

I can personally attest to the fact that the Power Poles will stay connected
in a mobile installation under some rather extreme stresses.  Check out the
Jeep section of http://www.JeepGunner.com and this article specifically
http://www.jeepgunner.com/jeep/mfj1.htm.  That Jeep hit some very extreme
trails (Moab and other places) and very rough dirt roads at speed from time
to time.  We never once had one disconnect on us - they always stayed tight.
We used Power Poles at multiple points for the overhead mounted radios as
well.

The one concern I have about Anderson PowerPoles is that they are not a
positive locking connector. They depend on friction to stay connected.
Without some sort of lock, they could vibrate apart, especially in a mobile
installation. Don't get me wrong--I love PowerPoles and use them in other
applications. But they do have limitations.

For my mobile installs, I use a Blue Sea Systems blade fuse block. 
They are available with either 6 or 12 individually fused circuits and they
use screw terminals for a positive, vibration resistant connection. The
block comes with a cover so your connections are protected. And the design
makes for a low-profile installation without wires sticking out
perpendicular to the panel on which the fuse block is mounted. You can buy
these fuse blocks from West Marine (on-line or at one of their many stores
around the country). A little pricey, but I've never had any problems with
them.
