Wire Corrosion

[rfitzpatrick]

While inspecting my ignition, pulled the coil wire from the distributor, pushed back the nipple and the medal connection fell right out!! Thought this area was sealed somewhat-- corrosion reached quite a distance --- what can I do in the future to prevent wire corrosion?

Dielectric grease prevents corrosion but it does not conduct electricity.

No-Al-Ox is a conductive grease that is usually used with aluminum wiring.

For a while houses wired with aluminum wire were burning down due to "hot spots" at the wire-nuts. Aluminum "skin oxidizes" which is effectively an insulator. No-Al-Ox solved that.

But it also works well on ANY electrical connection.

I use it under the clamps on the battery post. Never had the "white oxide."

I will second what Seth said.

I use Dielectric grease on all electrical connections, including in light sockets to prevent corrosion.

I am assuming you live in Florida in the Coral Springs area which is very close to the coast. The moist salt air is probably acting like an electrolyte and when combined with a voltage source it can be very corrosive. Using a dielectric grease is a good idea.

Yes, I do live a few miles inland. Was shocked to discover the corrosion on a relative new harness tho. I'm cleaning and using that item mentioned. I thought the spark plug harness nipples were sealed, somewhat

If there is a gap that spark is jumping between the wire and connection there will be corrosion
