Electrical connection

[Dean The ResourcefulNorse]

Has anyone had any experience with "electrical grease"? As opposed to
dielectric grease?



I'm having trouble with a multiple pin connection in a ribbon connector and
I can't squeeze it to make it tighter. I can squeeze it with my fingers and
make it work but not with a tool.



Motorcraft has a product for one. I just need to put something in there to
help make that circuit.

Dean it is basically the same. But make sure you read the first paragraph on this Google page.

"Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion. ... The
grease does not conduct electricity, so it shouldn't be applied directly to the mating surfaces (pins and sockets) of an electrical connection. Feb

Re-reading that, I didn't really answer your question. You probably need to clean out the "grease you have in the socket and only put it in so it
doesn't inhibit contact to your multi pin plug. I didn't realize that myself but I've only used it on single pin plugs and I guess I've been lucky.

Thanks, now I have to go back and recheck my work. No, really thanks.

Dean,
I think you may be referring to "conductive grease", not dielectric grease. This is also sometimes labelled "carbon-conductive grease", and
contains carbon powder, or alternately, copper or aluminum powder, and does what you're looking for. It is used to prevent corrosion and improve
conductivity. Several companies make it. The stuff I use is from MG Chemicals (a Canadian company, but also distributed in the U.S.).

Caveats include: 1) It's not really made to bridge large gaps at high current. 2)It sticks to fingers like Moly grease. 3)Be sparing with it,
especially on multi-pin connectors. It CAN short pins together if it's blobbed on. Then you'll have to wash it off with carb cleaner, brake cleaner,
or similar.

Dean, I should have given you this for cleaning those contacts when we talked on the phone. I gave this same information to Jim K. today. I believe
Home Depot sells it.

Dean,

I don't understand - what do you mean that you can squeeze the connector/connection with your fingers but not with a tool? Nearly every one of my
tools are stronger than my fingers...

The ribbon cables I've encountered are generally not used in exposed locations and I've never seen one that had any type of grease in the connector.
Others with more experience might have different opinions, but I would not use any grease on a ribbon cable that has an iffy connection.

The question of the correct use of dielectric grease pops up every so often, and it's akin to a tire or oil "war" - everyone swears there's only one
right answer and there are a whole bunch of different answers.

https://www.permatex.com/products/specialized-maintenance-repair/electrical-system-maintenance/permatex-dielectric-tune-up-grease-2
The pertinent part:
"Coat both parts of terminal contact with Dielectric Grease.
Reassemble maintaining metal to-metal contact."
Seems pretty explicit to me - it won't interfere with an electrical connection... if it's a good connection to start.

I found this page very informative:
https://www.w8ji.com/dielectric_grease_vs_conductive_grease.htm
The pertinent part for your question is at the very bottom of that page. "Conductive greases should never be used in low pressure electrical
connectors, or in connectors with multiple terminals."

A little further up from the bottom: "One incorrect logic is the "dielectric" in "dielectric grease" means the grease should only be used to insulate.
All greases work by the low viscosity allowing the grease to completely push out of areas with metal-to-metal contact."

If the connection is good the dielectric grease will preserve the connection. If the connection is iffy the dielectric grease won't improve it.
