I hate to do something that would seem ... rather stupid, but here goes: As the post title indicates, I have an interesting starter. This is on a '54 GMC, I understand that it is bad to hook 12V up to it, but I did just for a second to see if the starter motor was fried, and the little sucker just started whirring without any key or push-starter behind it -- Has the 12V battery fried something, or am I missing some cutoff wire here?
