No change. Grrrr.

Thanks for the idea CTScott, I will try that. Just follow the wire from the alternator to where it ends?

Yes, you can follow the wire up, or pull off the positive battery terminal and you will see where it connects to on the bottom of it. If you are seeing over voltage, then it isn't corroded contacts, but rather a bad regulator.
