Stone Cold Dead

[Buzz]

While removing the alternator to install a new high volume water pump, I accidentally grounded one of the terminals against the cylinder head. I had stupidly neglected to disconnect the battery beforehand and now the entire electrical system is dead. The battery still shows a strong charge, but that is it. No lights, horn, instruments and no igntion. I understand that grounding the alternator can destroy it , but does it sound like I fried something else as well? Bear in mind that I still have the Chevy engine in the car and the alternator is a GM 3 wire unit. I have already ordered a new alternator from Summit, but in the meantime (about a week) shouldn't there be some sign of life in the rest of the system? What should I look for first? Any help will be deeply appreciated.
