That was the connection I was talking about that I looked at but I didn't really see anything that looked like corrosion on there, it's also the same connection I stuck a small washer in. And if I'm not mistaken it was silver looking, but I believe someone said they can be nickel plated?
Yep the contacts are silver in color. Scuff these up with something. Mine looked nice and shiny but after I hit them with sand paper I had spark.
