    Check the voltages on the rectifier board and report back

    #4 3 years ago

    And do you have voltage at the lamp sockets?

    Looks like you have switched illumination buss on J1 pin 7 for the playfield and J3 pin 6 for the insert panel. If the controlled lamps are out on the playfield and the insert panel then it is less likely it's a straight power issue.

    At this point I am less certain about how the lamp circuit works. I know it is 7.4 VAC and voltage should be present at each socket at all times. It is not obvious to me how the AC circuit returns to the rectifier board.

    Another thing to check if you have voltage at the sockets would be the connectors at the MPU and LDB. Lower left on the mpu and upper left on the LDB. If there has been any serious corrosion on the mpu both of these could be suspect.
