Yes.. its the reset mech. At start up this whole bank will be enrgised to reset all the switches. There is another coil attached to each of your " metal thingys" ( LOL) and as each relay comes into play, the coil energises pulling the relay switches down again.
If your reset relay is in here and its not closing/operating properly then the motor will just turn continually

Got it  . somethig is holding in the GAME OVER reset, this shouldnt be hard to find. Thank again
