Corrosion where wire joins distributor cap.
I'm hoping someone has an idea as to what caused some serious corrosion in the distributor cap of my 87 560SL
This isn't inside the cap where you would expect to see it. Its where one of the plug wires plugs into the cap.
I was looking into what had caused a fowled plug and found a heavy white powdery corrosion in one of the holes where the plug wire connects. It was so extreme that there was very little juce going down the wire to the plug. The other seven where shiney as new.
After sanding and scraping it all off all is well.
My question is was this caused by a resistance problem with that plug wire or just some corrosion the just happened to occur on one connectin.
Thanks in advance
