To quote for the learned article:
"The important physical characteristic is that any grease must have low enough viscosity to push out of the way at contact points, be water or liquid resistant, and be stable enough to remain in place as a protectant against moisture and air for a long time. It will not do any good to apply a grease that does not do required functions of excluding air and moisture, and lubricating the interface to prevent galling or fretting, for extended periods of time."
"Contrary to Internet rumors, advertisements, and articles low viscosity silicone dielectric grease will NOT insulate pressure connections. Silicone dielectric grease will prolong connection life as well as, and have just as good conduction performance, as a properly selected metallic powder grease (conductive grease). On the other hand, and improperly selected "conductive" grease can actually cause connection problems."
The female portion of the multi-pin connectors lose tension over time. That is the problem. Ford Motor Company, in the 1960s used conductive grease liberally on the multi-pin connectors carrying power here and there in its relay driven masterpieces of the day. The arcing between the male and female parts of the connector caused hard carbon to form creating resistance in the connection.
On my journey to this age, I finally decided that clean and dry works for me, so I apply readily available plumber's silicone grease to the non-conductive parts of multi-pin connectors to try and keep moisture and dirt on the outside where it belongs and trust on the lubricant left behind by Caig Product's DeOxit to keep the metal parts from corroding. Or I solder and shrink wrap everything in sight.
