I would have to say oxidation. Copper oxidizes really fast when exposed to air. Just clean them up a little before you hook everything up again and you will be fine. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Tin the ends of the wires prior to inserting them again and you will not have the issue...

I wouldn't tin the power wire though, just the rest of your cables...

Copper shouldn't oxidize to black for several months in my area, I know it works faster near oceans with a good deal of salt water nearby, but in my area, I can have it exposed for a year without issues.

You lucky devil. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I can get by out a month with out wire oxidizing. It must be something in the air around here. I put copper gutters on my house the begining of spring and they are already a nice blueish black hue //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
