Gave my TAF a very quick once-over with some Novus and an LED kit before I put it on route. After reassembling, the train wreck flasher didn't work. Didn't want to mess with the ramp, instead wrestled the plastic out from under it to check the bulb connection. In the process, it scraped against the Thing ramp/scoop and put several scratches in the stone art.
The flasher didn't work because it wasn't plugged in underneath the playfield...
