Anyone know? -------- Original Message -------- Subject: What's Inside Aircraft Jumper Cables? Date: Thu, 18 Oct 2007 09:24:42 -0400 From: Paul Dow (Remove Caps in mail address) Organization: Cox Newsgroups: rec.aviation.piloting A friend of mine has some very nice aircraft auxiliary power cables, and he was going to take it apart and remove the insulation for the scrap copper. After seeing how nice it is (4/0 stranded cable), he put it back together, but he noticed something strange. Inside the plug connector was a 50 ohm resister in series with a diode connected across the two cables. Copper pins were inserted into the braided wire to make the connection. Does anyone know what that is for? Thanks
