Hi all. I have a new King Rock project, and I was hoping I could get further before posting here. I'm hoping someone can provide me some direction. When I turn the machine on, there are no lights anywhere, except for a lone coin slot light. When I press start, I get a one third turn of the score motor and it stops. Every time I press the button, I get another one third turn. The start relay fires, along with the replay button relay. The hold relay also fires and locks. That's about it. The start relay does not lock like it should. I have investigated the many tilt switches and bounce switches and I believe I have them all in the right state. I do have a question about the tilt switches, though. On the schematic, they are all three in a parallel and are all normally open. When I test the continuity on both sides of these switches, it buzzes. Does that mean at least one of them is closed? Anyway, I'm unsure if a tilt switch would be to blame for these other issues. If I close the tilt relay, some of the lights on the playfield come on so there is power there. I can't get anything in the backbox to do anything, no lights, no relays. The only exception is that if I add a credit to the credit wheel manually, the knocker fires (in the cabinet). It's all very confusing. Any thoughts on where to look next? Many thanks in advance.
