This is an odd failure indeed. Make sure the mag plate is tight and has no side slop. Perhaps the flywheel was rubbing on the flywheel which initiated the damage. Be sure to use the proper tool to set up the proper charge coil/sensor coil/alternator winding distance from the flywheel magnets. Be sure the engine wiring is in good shape also, stray voltage being inadvertently routed through that charge coil will cause this type of damage also.
