Have you attempted solenoid test to see if the wheels spin only during their part of the test?
I don't see how removing ribbon 1 would impact the wheels spinning. That is an output only ribbon to the sound board. The sound board and MPU (and for WW, the SO board) operate "open loop". There is no feedback from the sound board in any System 11 game.
