Thermistor - 8 Amp 2.5 ohm R25 ~

Thermistor - 8 amp 2.5 ohm R25

The thermistor is installed in the power box of Williams/Bally WPC System pinball machines in series with the black power line wire

The thermistor limits the inrush current when the machine is first turned on. This reduces stress failures of power handling semi-conductors further downstream in the power supply system

This part will be warm to the touch

Cold machine resets when the flippers are activated may be caused by a bad thermistor
