Service notes: A 12 V DC motor switched by Q26 through J122-1, fuse F103 (3A S.B.). Power off, it should turn freely by hand; a motor that hums but does not turn has a jammed gear train or a bound mechanism, not an electrical fault. Its flyback diode ties back to the driver board through J122 in a shared pair with the coil next to it, so a lost tieback wire, terminal or diode kills the transistor and can leave the motor locked on. Check both J122 tieback groups after any work under the playfield. A2 Coils, magnets and motors
