Quoted from CrazyLevi:

How did you fix this? Rebuilding the connectors? Or were there rectifier board issues?
Me and the OP are trying to figure out the same issue on the same game.

I also had a similar issue, it was caused by my poor "repinning" of the solenoid ground return on the SDB. I think it's on J3, one of the .156 connectors (check schematic for Solenoid GND). Once I located the poorly pinned wire, the solenoids returned. Check that you have continuity from the pin, along the wire to the playfield as mentioned in the post above.
