Avionics: Redo of right side LEMO jack (plus filter capacitor).

The original install of my LEMO jacks went well.  But after about a year, the right side jack would need a little jiggling every now and then, lest I can't hear my passenger speak.  The mic wire was clearly loose.  So it was time to replace it.  Also, though not noticeable in flight, since I have a bit of alternator whine in the intercom, I thought to add a filter capacitor whilst I was going to replace the jack.

Go here to see how LEMOs are wired.  Here's how that process went. 



Wired up to the PTG.M0.6NL.LC65N jack.


End cap on with wires ready for the Molex connector (go here to see part numbers).


Sealing with siliconized latex caulking.


Installed.  You can see the filter cap on the right. This view is looking down.
