Quoted from cottonm4:
On the J-1 connector on your rectifier board, it appears your white GI return wire is in the wrong slot. The white wire should be in pin #8, not #7 as you have it placed.
Strike that. I see that you are using a 9-pin wafer for J-1 so your white wire in OK.
You are missing one blue wire for feature lights. But the 2 blue wires on my connector are bussed together on the rectifier board so it is probably not causing your problem. However, the 2 blue wires on mine feed different groups of feature lights inside that cluster of play field wire harness. You are probably OK with just the one blue wire but I am wondering where the other blue wire is at.
The blue/white wire at pin 6 is the flipper power wire. I would suggest double checking all of your connectors inside the A2-J1 wafer. If you used the Trifurcon connector pin in the bottom of this pic you are probably OK. But if you used the flat style of connector on the top you could have a connection issue. Those flat connectors like to fold up and give lousy connection.
