Bob,Your current use of dielectric grease sounds fine to me. True, dielectric grease is a non-conductive element but will squeeze out of the way with nearly all tight connectors and create that "barrier" against moisture that inhibits conductivity over time - therefore dielectric grease is said to aid in conductivity.
The metal to metal contact provides our sufficient conductive energy transfer in my mind and sealing this with lithium/axle grease/Vaseline...or our such is excellent at sealing out the elements.
I have heard, but not searched for or purchased, conductivity products but I tend to think what you are doing is perfect for conductivity and sealing - no need to search for the lost chord as you have it mastered.

http://www.allpar.com/history/mopar/electrical.html
I have used plain old axle grease and spray white lithium grease with no problems but recently somehow I got the idea that dielectric grease was better. I learned in Navy electronics school that dielectric substances are electrical insulators, so I'd been reluctant to use it. Then someone mentioned that the metal-to-metal contact would carry the current and the dielectric grease would prevent unwanted conduction (shorts). I've been using the dielectric stuff, and recommending it since then with no problems. That said, your statement about "used liberally" got my attention. I would like to use the best conductivity grease on my contacts that I can find. Realizing that the purpose of using grease of any kind is to fill in any gaps in a connection to prevent air and (especially) moisture from promoting corrosion, which we know is the cause of most of the electrical problems in classic and antique vehicles. The spray-on white lithium is really easy to use and less messy than other stuff. Lithium is a metal, so it probably conducts better than a dielectric. If there's a better conductive lube, I want some! Thanks BC On 10/12/2013 7:10 PM, Gary Pavlovich wrote:
Remember that dielectric grease is used to seal connections like on our spark plug wires/boots from moisture/debris...but if used liberally on electrical connection surfaces they will prevent proper conductivity. There is a special lubricant for conductivity.
