    In print unit#3 the impression on 1 does not turn off for solenoid 3Y12. The solenoid is terminated in the LVT box, 3LVT1 FAM64 XA:12. During the blanket wash it does not turn on and off as it should. It stays on all the time even during printing which results in wiping the cylinders down on every stop. I swapped out the FAM64 board with unit #1 but the problem is still there.
    Does anyone have any information on where to check upstream in the wiring for this circuit?
