Will it work ... YES. Been there, done that.

Was checking the plugs one day and dropped the last plug and it hit the starter positive and shorted. I heard a BANG that sounded like a gunshot come from the back of the car. My first though was that the battery had exploded but when I opened the trunk it was intact. A subsequent search revealed the ground had blown off. It was one of those thin stamped copper ends and it had blown off at that contact point. Kinda lucky it did I guess !! So there's something to be said for having weak points in systems !!
