Arcade Schematics and Wiring Diagrams
Download arcade schematics and wiring diagrams for original classic arcade games. These digital PDF documents provide technical information for identifying electrical connections, tracing circuits, diagnosing hardware problems, and restoring original arcade machines.
Each product listing identifies the applicable arcade game, manufacturer, PCB or cabinet version, document number, printing, and included diagrams when known. These are digital PDF downloads. No printed schematic package or other physical product is shipped.
What Are Arcade Schematics and Wiring Diagrams?
Arcade schematics show the electronic circuits and components used in an arcade machine, while wiring diagrams show how the PCB, power supply, monitor, controls, coin door, speakers, and other cabinet components are connected. A schematic package may contain one drawing or multiple pages covering different sections of the game hardware.
Information a Schematic Package May Include
- Main arcade PCB circuit schematics
- Power supply and voltage connections
- Cabinet wiring and wiring-harness diagrams
- PCB edge-connector and pinout information
- Monitor and video-signal connections
- Joystick, button, and control wiring
- Coin-door, service-switch, and credit wiring
- Audio circuits and speaker connections
- Component designations, test points, and original part references
Confirm the Correct Game and Hardware Version
Arcade schematics may differ by game revision, PCB version, cabinet type, manufacturer, document number, or printing. Two cabinets running the same game may not contain identical wiring or hardware. Review the complete product description before downloading to confirm that the documents match your arcade machine.
Some operator manuals contain schematic pages, but this category is intended for dedicated schematic packages, drawing sets, and wiring-diagram downloads. The product description will identify the available contents whenever possible.
Technical Knowledge and Electrical Safety
Schematics and wiring diagrams are technical reference documents and may assume prior experience with electronics, electrical testing, and arcade hardware. They do not provide step-by-step repair instructions for every possible problem.
Safety warning: Arcade cabinets may contain hazardous voltages. CRT monitors can retain a dangerous electrical charge even after the machine has been unplugged. Disconnect power before servicing and use a qualified arcade technician when you are not trained to work safely with arcade electronics.
