Hey. Got sidetracked, old folks, funeral arrangements, you know the drill.
So, wait, what? Dielectric? But that's an insulator. And we are talking about marginal/corroded/Luigi'd connectors. The idea is to improve the contact, reduce resistance, protect the contact, which, silly me, means some sort of a conductive grease, IE an "electrical contact lubricant".
Whut am I missin'?
