Quoted from zacaj:I've had resetting issues on my WPC games even at 115V. Rebuilding the power board helped but 113 definitely is low... I haven't found any way to high tap WPC either
Look at the WPC Schematics, the "Power Wiring Diagram Sheet 1 of 1". In the center of the page it shows you how to pin your voltage selector Molex plug. If 115v is too low, use the pinout for 103v.
