Battery installed backwards

Wondering why the fuse blew, if the battery is connected the right way around it would see the rectifier as an open circuit, the wrong way around and the battery would see a short circuit and blow the fuse. Damage could arise with the high current through the rectifier diodes if the fuse is slow, but if there were no rectifier as soon as you turned on the ignition you would blow your electronic ignition system unless it was reverse polarity protected which I doubt on motor cycles.
