Works well except for this issue. I am stuck, could use some advice. On the bomb targets the coil activates to reset the targets when your coin the game up. It stays activated in the up position (which is actually with the coil down in this case) until I shut it off. The pic shows the coil disengaged, it is getting stuck in the opposite position. Loud hum of course. I dont do many EM machine, in fact this is my first so some help would be great.
