Yes, as long as nothing has been added to the grease to make it conductive. All grease is non- conductive (a good dielectric) to begin with, as are all petroleum products (oil, gasoline, etc., etc.) but adding material like moly disulphide ('moly'), graphite or actual metals (like all anti- seize contains) will add a conductor to the grease and that should not be used. If in doubt, just buy true dielectric grease, which is almost always a silicone based grease and safe to use on about everything in the world (Easy Boys! I know what you are thinking!).
I personally tend to use brake grease because it smears so well and I can use a thin film. But I have also used axle grease as well as chassis grease (avoiding graphite types) for decades. When I was a kid, I used to hang around with an uncle (actually my mother's uncle- yep, he was old) who never would install a bulb in a car without first swiping it with grease. He used chassis grease right out of the nearest grease gun. I thought it was some kind of foolish ritual like throwing salt over ones' shoulder (I apologize in advance to all of those who throw salt over their shoulders

) but as the years went by and I found bulb after bulb frozen in various cars sockets, usually taillights, I figured out that it really is a good idea. And now I never change a light bulb without a small amount of grease on the base and I have never had a seized lamp base on a vehicle. Although today most sockets and lamp bases are plastic but still- a little grease never hoit nothin'.
And for anyone who has ever had a fuze corrode in the socket on a vehicle, guess what the fix for that is? Yep, a dab of grease on the connections before installing the fuze will prevent that too. In fact, Kirby absolutely insists all Incontrol products use industrial grade, genuine 3M, 'you cannot buy this in any retail store' brand dielectric grease at the point of manufacture..... so for those who have removed the fuse on, say, a KiPass activation switch bypass and wondered "What is this wet, greasy looking stuff on the fuse legs?" well, it is grease. Kirby personally guarantees that no Incontrol product will ever have a fuse corrode and make a customer say some very bad words at the very moment he / she absolutely needs to remove that fuse to start the bike....
All of which brings us to the origins of the ancient saying 'If it resists, slap some grease on it and push harder!' (Extra Easy Boys!)

Ok, all that said, then what makes a grease a "dielectric" grease? Will any old grease do?
