I previously had an issue with my Dr Who where several solenoids/optos were firing causing a weird issue. The playfield moves without knowling location, ball shooter, tardis popper, MPF ball ejects all fire randomly. Last time, everything passed tests and when checking connections, the problem resolved when I removed unplugged and reseated J117. It's now doing the same thing again, but everytime I try to check, fuse F105 blows. Reseating the plug does not fix it this time. A short somewhere? Any help would be appreciated.
