Just finished a restoration of a STTNG, and powered it back on for the first time. All the solenoids locked on briefly, and I turned the game on. I inspected the backbox connections, and noticed that the ribbon cable between the fliptronics board (upper right) and the MPU was connected backwards. I fixed that and when I powered the game back on the solenoids didn't lock on (not sure if its related). The solenoid fuses all seem good, but there is no voltage at the coils.

I'm going to dig in the manual and start working from the transformer on, but wanted to get a post up to see what you guys thought in the meantime.

solenoid secondary fuse F112 appeared good but tested bad. All is working again.
