 Posted: Fri Jul 04, 2008 8:26 pm Post subject: Strobe shielded wire splice |
 |
|
My RV-9A wing strobe wires will be a little short in reaching the
fuselage mounted power supply. I could buy some longer wires, but I
have a spare set that can be used to splice on some extra length. Any
problem splicing as per this:
http://www.aeroelectric.com/articles/Shielded_Wire_Splicing/S_Wire_Splice.html
In case I want to have a wing to fuselage strobe wire connector (I know
the pros and cons), is there an issue about having the Molex connector
unshielded? In this case, do folks just run solder the shield ends to
once of the Molex pins?
Thanks,
Carl

That would be just fine. The shielded wires that come with most strobe
kits is the Beldfoil with drain wire . . .

. . . as opposed to the overall braided cover but
principals are the same. The very short exposure
of adjacent wires in bundle to the "uglies" that live
in the strobe cables is insignificant. It's a common misconception
that a break in the shielding of an antagonist wire is an
opening that allows ALL that is bad within to escape. Not
so. The splicing technique described will function as advertised.

Normally, shields are taken through a connector on its
own pin as if it were one of the signal carrying conductors.
Pigtail the shields on either side as described in . . .
http://aeroelectric.com/articles/pigtail/pigtail.html
. . . or in the case of the Beldfoil shields, trim the
shielding foil back to the outer jacket and take the
drain wire through the connector as a separate
conductor.
