I have an Olympic Hockey that is not behaving properly. I took apart the lower left pop bumper to put a new platter on and now it's acting weird. When a game is started, only the lower left pop bumper light is lit. It's normally supposed to be dark and light along with the upper right pop bumper when a lane is activated (thereby increasing the score from 10 to 100 for these bumpers). When I activate the lane, the upper right light goes on and the lower left one goes out. Both pop bumpers score correctly (10 or 100 when the lane is activated). It's just that the lighting for the lower left bumper is reversed. I haven't had the game that long and don't remember if it was doing this before I took apart the pop bumper. I took it all apart again and put it back together and it's still acting the same way. Any ideas? The schematic snippet is below. Thanks in advance for any help.
