I just got my first shuffle alley so this post probably belongs in the arcade games section https://pinside.com/pinball/forum/forum/em-arcade-games
I am having to clean ALL the stepper units as they are gummed up and I suspect yours needs to be cleaned as well
I am working on a "full reset" stepper at the moment and the rivet that holds the pawl away from the gear so it will reset all the way to starting position needed a whack with a hammer so it would actuate freely
I suspect the fuse blew from the coil trying to power its way to move the gear & I suspect the score motor keeps turning now because it cannot get to starting position.
some great info here http://www.pinrepair.com/em/
