Quoted from Mr_Outlane:Williams WPC Bram Stoker's Dracula flipper's intermittently go dead during multi ball. Most times it's only for a second or two, other times, I have to reset the game with menu button to get power back. it does not occur often. Any suggestions welcome.
Sounds like you’re having a voltage drop. Have you checked 5 and 12 volt testing points on the power driver board?
