Check to see if you blew a fuse on the disconnect solenoid. IS that where the buzzing is coming from? You may have damaged it.
The easy way to test that is to jump it by moving one cable over to the other side. IF everything works then you know the solenoid is toast.
Check the shortstop breakers in the Battery Control Center and see if one is tripped. Push the black button back in to reset it. Having a small digital multimeter would be very helpful here and cut down the time. About $20 or so at most hardware stores.
