WMS WPC RESET Heartbeat Restorer
Williams/Bally WPC plug-in reset prevention board with voltmeter

Plug-in board that stops intermittent resets on Williams/Bally WPC-089 machines caused by marginal 5V supply to the MPU. Installs inline on the J210 connector — simply unplug J210 from the MPU, insert this board, and plug the original connector into the top of it.

Includes a built-in digital voltmeter so you can monitor the voltage supplied to the MPU at a glance.

Used on all Williams/Bally WPC-089 machines that experience intermittent resets.

Note: This is not intended as a permanent repair. It is a reliable temporary fix and diagnostic aid while the underlying 5V power issue is properly addressed.
