Dielectric Grease and how to use it

Some guys were recommending coating all connectors on their F3s with Dielectric grease (on some of the throttle problem threads).

Did some youtubeing and found some vids in contradiction to their advise.

So, what is ? Apply to the connectors or just the rear exposed parts of the connectors? The second vid shows that metal to metal with dielectric grease wont do much to voltage.

Common sense seems to have no room in electrical applications.

Well... I used the famous ACF 50 on and in the connectors. So far so good with zero problems.

What a beast of a motorcycle!
It growls and rages and flies across the tarmac like a wild animal that has escaped the confinement of a cage and after merely waiting restlessly until the release, will not endure being locked up ever again.

Donsy knows.

Just a bit of common is required. If the connectors have a strong spring action like on Lucar connectors then use a bit of dielectric grease and youll be maintaining metal to metal contact.
If you coat the pins on your F4 indicator bullet connectors with it then the grease will live up to its name...DIE electrics : )

The maker of Permatex tuneup dielectric grease provide the following instruction:
1. Make sure ignition system is off.
2. Clean surface with Permatex® Contact Cleaner.
3. Coat both parts of terminal contact with Dielectric Grease.
4. Reassemble, maintaining metal-to-metal contact.

https://www.permatex.com/products/lu...e-up-grease-4/

I personally think this guy's hypothesis makes a lot of sense (whether it's common or not???)

My own personal view without any technical basis other than what I've read here is, if the connector exposes the terminals to the elements, it could benefit from dielectric grease.

Paul, the terminal, in your example, would also benefit just as much from a smear of axle grease.

Dielectrics ISOLATE current flow. They are insulators.

If there is a gap in the contact zone, and dielectric is introduced into that gap, the circuit will not work.

Yes, agreed, in terms of protecting the terminal against oxidation.

This is also another benefit, and I think this is where dielectric grease is really beneficial, particularly for high voltage/current situation.

I don't disagree with this ^^, but I also think if there is a gap, then the problem lies in the integrity of the terminals more so than grease (whether that be axle or dielectric grease). On the other hand, if that gap is exposed to the elements it would initiate oxidation and diminish the performance of the terminals (in absence of protection such as grease). I remember back in the days of slot cars, the guy that runs the track used to put on a layer of sewing machine oil on the track every now and then with a cotton swabs, I didn't think much of it back then, but per the context of this thread, I now think it's to protect the track.

if there is a gap in contact there is no connection......dielectric grease or no

Please refer to Section O, page 2 of the Service Manual up through 312RR

this is the electrical trouble shooting guide.......

what are the 2 most frequent fixes??????

Deoxidize/Repair and Replace

now go look at the package for Permatex #22058 what does it say????

"Protects Electrical Connectors From Corrosion"

you think maybe that would stop all the Deoxidize/Repair problems??????





I live 3 blocks from the Pacific Ocean......I have no electrical issues.......

I use dielectric grease...... my '66 ElCamino has spent 51 YEARS outside at the beach

General Motors used dielectric grease on it......no electrical issues

Joe's example is silly we all know that front indicator problems are related to torque

on the 2 fairing mounting bolts.....everything is rubber mounted and wiggles around

Ha ha..I almost choked on me Weetabix Noel..; )

I is talkin about the indicator bullet connectors and not the contactor plates..

The connectors are a male and female fine pin and bore...and they can fail if you use dielectric

Now where did I put my twirly bow tie hee hee.
