3 Technical Info

Coil cross reference:

Midway # A614-00014 (red wrapper) 4.3 ohms resistance is the same as Bally # AP-24-725. These are typically used as thumper bumper coils.

Midway # A614-00016 (blue wrapper) 1.4 ohms resistance of the main winding, 16.5 ohms resistance of the hold winding is the same as Bally # AF-23-300/28-1000. These are typically used as flipper coils.

Midway # A614-00017 (white wrapper) 3.8 ohms resistance is the same as Bally # AP-23-750. These are typically used as slingshot kicker coils.

Midway # A614-00047 (yellow wrapper) is the same as Bally # AP-23-575. These are typically used as the outhole (ball return) kicker coil.

4 Problems and Solutions

4.1 Power Problems

Series 2 power transformer box assembly uses Littlefuse twist tab mount circuit breakers instead of fuses. The red shaft of the circuit breakers stick out the rear of the cabinet in a slot. There are three 2.5 amp hold, 4.0 amp trip breakers and two 3.9 amp hold, 6.0 amp trip breakers mounted to this transformer box.

The gray wire from a 2.5 amp breaker feeds the controlled (switched) illumination circuit. The black wire from a 2.5 amp breaker feeds the left thumper bumper and left slingshot coils. The yellow wire from a 2.5 amp breaker feeds the right thumper bumper, right slingshot, and outhole (ball return) coils. The brown wire from a 3.9 amp breaker feeds the 6 volt playfield general illumination circuit. The blue wire from a 3.9 amp breaker feeds backbox general illumination and gameboard logic supply. There are two windings of the power transformer that are NOT fused: the 120 volt primary and the 18 volt (red wires) secondary. The power transformer used in the Series 2 power box is Midway # MT-60A.

4.4 Solenoid problems

All solenoids are "pre-driven" by integrated circuit Q203 (DM7445). Solenoid driver transistors are type SE9400 which cross reference to NTE 264.

Transistor S4 controls the right slingshot and is driven from IC Q203 pin 5.

Transistor S5 controls the left thumper bumper and is driven from IC Q203 pin 6.

Transistor S7 is not used on this machine and it as well as two resistors next to it are not installed. This solenoid would be driven by IC Q203 pin 9.

Transistor S6 controls the right thumper bumper and is driven by IC Q203 pin 7.

Transistor S1 is not used on this machine and it as well as two resistors next to it are not installed. This solenoid would be driven by IC Q203 pin 2.

Transistor S2 controls the outhole (ball return) kicker and is driven from IC Q203 pin 3.

Transistor S3 controls the left slingshot and is driven from IC Q203 pin 4.

Above pertains to Captain Fantastic.
