I think you should check your battery connections one more time. Take them off, clean and reinstall and don't forget the jumper between the batteries. After the spark occurs, go around and CAREFULLY touch the terminals, a bad connection will be very hot. (Use common sense here)

Jim, you may simply have burned up a battery terminal. If the connection was loose, you may have seen the sparks across the bottom of the cab. The second try could have opened the battery terminal completely. Should have made a bit of noise too.
