Bulb grease?

[Wingback73]

I have just a little bit left of a large tube of dielectric grease that I bought about 30 years ago. In other words, I've used a lot of it. I've known that dieletric grease is non-conductive for at least that long, and I was taught by well-seasoned, highly-qualified techs to apply it directly into the contacts of connectors that you don't want to corrode due to water intrusion. It's only purposes are to prevent corrosion and to prevent voltage loss between connectors. In all these years, I've never experienced a situation where the dielectric grease prevented electrical transfer from pin to socket in a connector junction.

The grease doesn't have enough shear strength to prevent metal-to-metal contact. I think you were experiencing another problem, like a slightly loose battery terminal that was inadvertently fixed in your search for a solution. There are more than one threads on this forum where a slightly loose battery connection vexed the TJ owner for considerable amount of time until it was discovered...

First, it wasn't a Jeep, and 2nd, that battery terminal wasn't loose. In fact, it wasn't even close to loose. Go back and re-read what I wrote; what fixed it was thoroughly cleaning all of the insulator off the terminal.

We all have a choice as to how we treat our vehicles; I'm simply pointing out for people that don't know any better that dielectric grease is an insulator, not a conductor, so it has no place on terminals. If you want to put it on yours anyway then that is your choice, but it seems pretty silly to put an electrical insulator on something you want to conduct electricity. Don't get me wrong, I use it as one would any other insulator around the terminals, but not on the terminals themselves.

Well then, we'll just have to agree to disagree.
