Had my BSD playfield up and the power off. Brushed my hand against something and got a mild shock. This was from the bottom of the playfield. Turned the machine on and now the opto switches for the castle and magnet aren't working (#51,53,54,55 & 56). Don't know if they had anything to do with each other. Anyone have any ideas? I'm going to look at fuses and connectors now, anything else I should look for?
