Bulkhead connections.....Dielectric grease..YESorNO?

[440669superbee]

Read pros and cons about using dielectric grease on bulkhead terminals....Just wanted to get the MOPAR experts thoughts on this.
I pulled them all out of the main bulkhead and cleaned and tweaked them, corrosion did not seem to be an issue, appears to be more of a connection issue on the J and P terminals through the bulkhead.
I just on the fence about using dielectric grease before attaching the three plugs again.
Like to hear what you all think about this.
Thanks for reading this...

Well first off, thanks for all the responses all good to know what people have used in their past experiences.
I decided to grease em up, (thin coat on male terminal) sparingly. cross my fingers and hope all is well for another 40 years, most likely won't be my problem then............

I have always been told to ! But I never do I haven't had any problems yet!

If already apart, yes. I just cleaned and assembled mine. Don't want to risk breaking a tab. If apart again, I'll use the dielectric. When using the spray it ran black for a good while.

on the bulkheads, I grease around the connectors then plug em in and grease them from the outside..after they're connected..kinda push the grease in from the wire side, I don't want it on the metal surfaces that actually touch and conduct electricity..you just want a protective barrier to keep moisture out away from the contact points..but that's me, there's always lots of debate on where to grease...

It is a good idea to use it on all the electrical connections in a car. People think dielectric grease is good for helping electricity flow (no it does not) but what it does is stop the corrosion of the metals. Electrical connections are susceptible to the chemicals and moisture in their environments. If a connection develops corrosion it can affect the way the entire electrical system functions. Dielectric grease keeps moisture out of electrical connections.

Always use dielectric grease on all my connections. Bulkhead too.

I pack the outside of the bulkhead connector after plugging the wire in. I use the grease mainly under hood where water may enter. In the interior water shouldn't be an issue.

Hmmm. I have never used the stuff. I just clean the terminals and snap it back together. Guys like Dennis H drive their cars far more than I do so maybe I should reconsider the stuff. Thanks for bringing up this topic.

Yes to dielectric grease. These cleaners are also a great tool. Industrial diamond on the tips.

I say “yes” too.

 

[moparjohnny]

I say “yes” too.

rust and corrosion is what cause the bulkheads to fester electrical problems and fires so yes it makes sense.

Well the stuff works' above great 'on semi's that travel 100,000 miles in one year; that's all the reason I need.

YES.

Using it for over 20 plus years and no "cons"

Couldn't have said it better myself.

You will notice NO difference now if you don't use dielectric grease because the terminals are clean. The payback for using it comes some time in the future when you are NOT chasing some goofy electrical gremlin due to a corroded contact.

Use it!

It makes bulbs easier to screw in/out, too.

Surprisingly, my bulkhead connectors where clean when I bought the car at 45 years old, but I used dielectric grease as an insurance like the OP did, a light coating on all the connectors & spades.

Not all " dielectric grease" is conductive and maybe an insulator so make sure of what you are buying.
On electrical connections I use Noalox, it's made for aluminum/clad connectors when there is disimilar metals (copper & aluminium)

corrosion did not seem to be an issue, appears to be more of a connection issue on the J and P terminals through the bulkhead.

While the dieletric grease protects againts agents, the problem on J and P cavities is more about terminals capacity to hold the load ( underrated charging system ) than the agents actions over the years.
