Confirm the Correct Hardware Before Service

Arcade schematics are hardware-specific. Compare board markings, drawing numbers, connectors, display type, and cabinet wiring with your Black Widow hardware before testing or replacing components. Alternate revisions, conversions, reproductions, and modified boards may use different circuitry.

These drawings are technical references and do not provide a step-by-step solution for every possible fault. Board-level diagnosis requires suitable electronic test equipment and experience interpreting schematics.
