Hi all. While performing my new years/spring tune -up on my Cobra,new plugs,
oil change, carb adjustment, timing check, filters etc, I came across something strange that I have never seen before.
When I removed the coil wire (351C with stock distributor and pertronix ignition module), the end of the coil wire in the top of the coil was quite stuck and when removed with a little more than normal effort/pulling, the brass connector end that sticks into the top of the coil was covered in a greenish corrosion.
The other end of the coil wire that goes into the top of the distributor cap was nice and shiney.
A test with a voltmeter initially showed no conductivity between the two ends of the coil wire.
When I scraped through the "green corrosion", with the tip of the voltmeter probe, the conductivity was fine.
The car ran fine before, so higher voltage was penetrating the "green corrosion", but it was getting harder to start.
So what gives?????? What caused the corrosion?
I just cleaned the corrosion off the brass tip, got it shiny again, and it will probably work just fine.
Right?
Cheers
Greg
