Bally Night Rider EM. I noticed the fuse was blown underneath the play field for the slingshots and pop bumpers. I turned off the game at the switch and removed the fuse and when I installed a new one, it sparked, even though the game was supposedly off. I then unplugged the game and put another fuse in and when I turned it on it immediately blew. So, what has gone wrong? Transformer, power switch, rectifier, what?
