Hello,
I have a black knight that powers up fine but the start button will not start a game. Switch test says that slam tilt and The right inside rollover are stuck closed. They are both in the same row (wht-vio).

The only other switches that show in switch test are the inlane and outlane switches. All other switches on the table do not register in switch test.

My guess is that the table thinks it is in a tilt scenario and has shut off all the other switches and the game will not start without knowing which trough switches are closed. I am getting better but I am still a newbie and this is the oldest table I have ever worked on. Could someone tell me what is the best way to proceed? I guess I am looking for a bad diode. Do I start at switches #7 and 15? Is there a better procedure for troubleshooting 2 switches next to each other on a row?

Thanks in advance. I would be dead without you guys...
