Hello Pinpeople !
I recently bought a Space Time Bally 1972. Machine is in rather good shape, plays well. Fiels is a bit worn out but that will be restored (winter project).
My puzzle is that the 00-90 stepper unit is not working. Coil was burned and removed when I got it. The wiring towards the coil also is gone....
I traced the wiring back with the schema. I appears that the stepper unit is linked to the 10 points relais. Which makes sense. In the top cabinet there should be a W-O (white orange) wire go to the coil. I wired this accordingly now. (see schema picture)
Then but when I trace back all the 10 points switches I get a bit lost.
These should be W-BLU (white and blue) wires
And I think they all come together on the bottom (facing front) most right board where I have all the coils sitting for the counting part. Coil number 6 looks not ok. My question :
-- > Am I right that burned coil number 6 on the photo picture is indeed the 10 points coil (Located at F-22 in the schema)
Thanks for your help!
