Hi All,

   FWIW department:  Since the time that Ford came out with
computerized engine controls, the connectors have been filled  with
dielectric grease.  Every auto parts store has the stuff.  The Ford part
number is D7AZ-19A331-A   It isn't cheap, but a 3 oz. tube might
very well be a lifetime supply for most of us.

   I'm only guessing, but I'd guess that a dollop of the stuff in each
connector would pretty much preclude corrosion of the pins.  I'm
not running yet (test stand) but that's what I'm doing.

Thanks, Bob.

I went with tin as my research indicated that was more than suitable - in 
fact I think (if memory serves me) that aircraft wire is tin coated to 
prevent the copper oxidizing.  My plug is exposed to moisture when the 
canopy is open, rain/dew, etc.  Also, I did not use any corrosion preventive 
such as grease or spray so given all that, perhaps the news is that it held 
up so well for so long.

  So given its been over 10 years, I guess gold is not a requirement {:>). 
Wow! $1200 and its not even solid gold {:>)

    

I found corrosion on the Molex connectors in the wing spar on the BD-4
when I had it apart.  It was completed in '79.  I replaced them with
new Molex connectors.  I think I would have opted for the sealed ones
if I had them readily available although I didn't even try to find any
at the time.  The $1200 is for a LOT of pins.  Each pin only cost
about 2X what the tin plated ones cost.  Some sort of grease to keep
moisture out of the connection might help.  I did a quick search of
Bob Nuckolls site but couldn't find any recommendations for it.

The other day someone asked about how to clamp the wires on DB
connectors on Bob's list.  I told him to wrap them with silicone tape.
I thought I had figured that out myself, but a little later Bob N.
answered with a link to a picture showing the technique.  I'm sure I
saw that picture a couple of years ago.  It works real good anyway.
