From plugs to plug wires

Post by saamiam »



So put some fresh wires and in one week all four of them look like this.. Any ideas? Electrical is my weakest skill.. so weak if i was a spark plug i wouldnt even spark.... lol

I appreciate all you gurus so much, your knowledge is invaluable.

The green is corrosion on the copper wire. Those wires are done.

Thank you very much for your rapid reply wing admin. You are correct and I do understand that it's corrosion. What I don't understand is why that happened at the coil side? The plug wires are only one week old. That shouldn't happen.

There could be a number of things contributing to the rapid corrosion.

First off, if it is not sealed from air, and it gets heat in there, it will accelerate the rate of corrosion rapidly. Oxygen + heat = corrosion. If it gets wet, that can also accelerate the corrosion. If what gets it wet is acidic, that accelerates it even more rapidly.

If what the copper is connected to is a metal other than copper (i.e. aluminum), galvanic corrosion can occur - the corrosion that occurs between dissimilar metals.

Dielectric grease might help prevent oxygen from getting to the wires to prevent corrosion.

Also if the coil side you are connecting "new" wires to is heavily corroded it will quickly transfer to the new wires. As Admin said after cleaning both very well (maybe trimming the new wire back 1/4" to remove all of the corrosion) I would add some dielectric grease and reassemble.
