Just put my recently acquired KOD back together after a detailed cleaning/shop out.
It started up, reset score reels and played (with a few scoring glitches) a game. On second start up, game reset score reels, back glass lit up but game shows "Tilt", playfield lights are not on and nothing else happens.
I checked the tilt switches and that does not seem to the problem. What I did notice is that when the control bank resets, the YB (2B-9B Sequence Relay) relay resets with the rest of the bank but then instantly trips. When you try to manually reset it, one of the switches is energized (loud buzz) and the relay instantly trips.
I have the schematic but am only so-so on reading them.
Any help is appreciated. Thanks -
