After work on the driver board, the outlane magnet fires whenever a slingshot fires (seen once Hocus Pocus is lit), the magnet fires at random, and the fuse for that solenoid group may blow.
Slingshot also fires an outlane magnet: ribbon cable not fully seated
Cause: A ribbon cable between the CPU and driver boards (or to the Fliptronic board) was not pushed fully home, so the solenoid control signals were corrupted.
Checks
- Check every ribbon cable is fully seated at both ends and not offset by a pin or a row: the short one between the CPU and driver boards and those to the Fliptronic board.
Fix
- Reseat all the ribbon cables firmly, then replace any blown solenoid fuse.
