Whats the voltage drop of the positive cable from the back of the alt to the battery? Possible corrosion there. Also, are all your connections good? What about the battery?

Secondly, where did you get the alt from? I've seen brand "new" alternators not charge right after installation....it's possible that it's simply defective....

New battery, connections appear to be good and tight, cleaned the battery connection on back of alt. I'm going to take the new alt. in for a test hopefully it is just a bad alt.

I can't really say what I did but it's charging now. All I know is there was sparks and now it's charging.
