Now, here is the electronics side of my take on this... and keep in mind Dielectric Grease is exactly what its name infers... It is an electrical flow stop or blocker! It has strong insulating, lubricating, and element protection properties! Dielectric grease is more closely related to electrical tape in what it's designed to accomplish.

Dielectric grease was developed to help lubricate and waterproof a connector but not to enhance the flow of electrical current! It is fully non-conductive, and should be used only to seal out moisture to help prevent contact and terminal corrosion. Therefore, it's not advisable to apply dielectric grease directly to the metal contact surfaces of the terminals themselves. It can actually inhibit electrical connectivity between low contact pressure connector terminals.

So, in the example BLAQHAWK has presented the more likely problem is one in which these very small primary connectors have developed high resistance from oxidation between the metal surfaces of the low contact pressure style terminals due to exposure to the heat, vibration, the elements, and what is known as Electronic Corrosion.

It's fully reasonable that by simply disconnecting and reconnecting the terminals to their counterparts that good solid connections were re-established. By applying a small amount of dielectric grease during this operation you may indeed help prevent the return of this often non visible corrosion from setting up again anytime soon.

Electronics stores sell a compound specifically for these types of connectors in the form of an Electrically Conductive Grease that was developed to enhance and lower electrical resistance across connecting terminals. It has to be used very cautiously as an application of too much of it might in effect create a metallic bridge across adjacent terminals in a connector that are normally isolated, and insulated from each other.

See electrically conductive grease here...

I have noted BLAQHAWK's case, and my view on fixes and compounds, as an update of important info on my link about coil failures below.


Dielectric grease information, IMPORTANT!

Ignition coil information, FYI.
