Smitty,
Id make sure you had all your wires right. even if you had to rewire it just to make sure! Id have to say YES you would probably smoke a chip if your A's and B's are touching.
A easy way to check if the wire of A and B's are touching, Just check them with your multimeter for continuity. Take your mutimeter and put the red led on an "A" wire and the black led on a "B" wire if it buzzes then you have a wire touching. NOT GOOD.. check all your A's and B's this way..
