Alternator?

[Elvis]

Well, I am totally confused now. While messing around with the ignition switch behind the dash I managed to pull loose a wire that runs from the ignition switch to a fitting that splits into two purple wires so nothing happened when I turned the ignition key. I finally figured out what I had done and reconnected that wire. Still nothing when I turn the key - no click, nothing. The battery is new and good, the starter is new. I will change the alternator but I don't think it has anything to do with the fact that nothing happens when I turn the key. I changed the little relay box that connects to the pole at the back of the ignition switch. No change. I know that power is getting to the ignition switch because I have seen some arcing when I got the back of the ignition switch in contact with the dash. When I turn the key to start the engine the light on my console that shows what gear you are in dims so something is happening. Could it be the ignition switch itself? What am I missing? HELP!!! E.
