[QUOTE="mcatrophy, post: 1347627, member: 3187"] I understand why you say that, but it's a bit(?) of a myth. So-called conductive grease is a very poor conductor, in itself it makes no difference to the conductivity of a connection. The electricity flows metal to metal. Any "power" connector relies on the sliding action of the metal contacts to push ANY grease (or dirt, oxidation or whatever) from where the metal to metal contact occurs. The conductivity of conductive grease is orders of magnitude worse than the metal of the contacts, so essentially no electricity flows through the "conductive" grease. Use whatever grease that will inhibit corrosion from creeping between the contact material, it makes no difference to the voltage drop across the connector. There are many references on the internet, one such is [URL="https://www.w8ji.com/dielectric_grease_vs_conductive_grease.htm"]here[/URL], I quote from it: The real use for copper-loaded grease is as anti-seize stuff, it's excellent for that. And it can be used in connectors, although I wouldn't use it as a lubricant for spark-plug connections - it is good for the thread (where the plug isn't supplied with an anti-seize thread). [/QUOTE]
