Hy! My Who Dunnit pinball is not working.
In the middle of game fuse f112 on powerboard blows and after that every time when i turn on game blows. I did replace BR3 and C8, check every coil for short but nothing. Any advice?

Is there anything plugged into J105 on your game? If so, unplug that and see if it still blows. If it doesn't, I might have a suggestion for you as I had one of the weirdest issues I've seen on a WPC game with a W?D concerning that connector.

J104 goes to your fliptronics board. You're still getting AC power via J102, so this leads me to believe that BR3 and C8 are indeed fine as they aren't blowing F112. I'd check to make sure your fliptronics board is fused properly and test the BR1 on the fliptronics board. It is possible it has failed based on this information and is what is sending the spike to blow F112.
