Electrical connections and dielectric grease

Gents,

There have been some interesting posts on here about foam support for relays and fuses, extra cable ties to support things, the use of dielectric grease, etc.

I hope to collect my new CR in time to really go through it before spring. So going through the electrics in a preventative maintenance way, is high on my list of priorities.

I’m quite happy in my abilities to help identify potential sources of mechanical failure of electrics, ie through stress and lack of support etc.

What’s new to me is the whole dielectric grease topic. I have only ever worked on the basis of ensuring connectors a dry and clean and using a squirt WD40.

Now we’re being told to slop grease inside our nice new connectors. This goes against the grain somewhat for this old dog!

Can someone give us a 101 on this topic? The idea of putting grease, an insulator, on nice clean fresh metal contacts is entirely counter intuitive to me!

Do I actually put the stuff inside the connectors, or only on the outside plastic parts, or what?
Fast Eddie, another solid subject. Again I'm a career automotive aftermarket manager but also guy that lives to play and work on my machines. The benefit of the use of dielectric grease varies based on environment. I live in Louisiana which Is warm and humid. I use dielectric on all my vehicles. Car, truck, boat, tractor and six motorcycles. Two things to be aware of. First use a quality product. I use Permatex. Cheap products often times produce cheap results. I've seen cheap dielectric grease turn to a brown sludge in wet conditions. Second is prep prior to application. WD40 (Water Dispersant) is a great prep produce in humid conditions or any conditions for that matter. Clean with WD40 prior to grease application. Apply to the connection surface and area only. Too much grease can work against itself and trap moisture. You will see the effect of moisture on brass and copper connections before aluminum. If you operate in a dry environment like Arizona, save you money and keep any connection issues in check with your WD40.
 
I've mentioned this in another thread but very appropriate here...
A product called ACF50 works brilliantly - apparently made for aviation applications
Not "gluggy" like grease but provides excellent protection and enhances conductivity
Really worth a look
By the way - give the pressure packs a miss - expensive plus the bottles (unpressurised) work better
Cheers
