Di-electric spray

Can di-electric spray be sprayed directly to the 7 pin cord on tt? I sprayed it on and several days later, as we hooked up to leave the CG, the tv trailer app said the tt was disconnected. After several minutes, it changed to connected trailer. Am I using this correctly?

Like said, di-electric grease/spray is non-conductive.

I use DeoxIT D5 by Caig;

Caig Deoxit D5 removes oxidation, something not all contact cleaners can do. I also use Deoxit Gold, it has the deoxidation chemicals and also a surface conditioner that protects from further oxidation.

A good contact cleaner for brass and copper is a mixture of vinegar and salt, it removes oxidation and can be followed with barrier dielectric material of choice.

Try Noalox. Lowes has it.

Electrical contact cleaner is meant for cleaning all surfaces that are meant to conduct electricity. It removes all residue that hinders conductivity and does not leave a residue. Follow with a 'light' coating of dielectric (silicone) grease to prevent corrosion. If the problem continues with your 7 pin plug, replace it. Cheap and easy. I carry an extra one with me because the casing can split easily.

Thanks for explaning when you would use dielectric grease. Things seem to be working well now.

I've used WD-40 also in a pinch. Generally I use contact cleaner. Many contact cleaners are themselves dielectric, meaning you can spray them on live electricals. Be sure and read the can before you try it with higher voltages. I doubt "dielectric spray can magically render conductive materials non-conductive unless they impart some heavy coating. I think the spray is named as such to prevent conducting current through the user. I could be wrong, though.

Well I have been useing w-d40, for four yrs on my steps , been good so far.now it's all happy camping

I have never used anything on the connector. The rare times I have had a connection issue, I used WD as a cleaner. Spray the male prongs, wipe them off with a rag and screw driver and go. So far so good.

I use Radio Shack's spray-on contact cleaner.

If your connection / connector was already "dirty" (ie. rust, oxide, etc), then a di-electric anything isn't going to help and will hinder. You need to clean the connection thoroughly and then put on some di-electric to prevent an issue. It will then allow a good connection to be made to a conductive contact as the dielectric will easily be displaced / "cut-thru" by the now clean / non-oxidized connector.

WD-40 would be better. It's for electrical connections.

I stand corrected.
