    Default Suspect Bad Fuji Thunderbirds 2 Classic Power Supply Board

    Think I have a bad power supply board on my Fuji Thunderbirds 2 (Classic) machine. When I power on I have power to some of machine briefly then goes out. No LEDs on other controller boards. Replaced the transformer and nothing really changed. Power supply board is FUJI P0301C KYOEI. I am about ready to reverse engineer the circuit board to troubleshoot but hoping someone might have some other ideas before I invest a lot of time. Replacement board or perhaps some circuit diagrams would be handy if someone has.

    I assume you have checked for fuses and tested the outputs from the board with a meter?

    Checked the fuses but without understanding of what signals/voltages are on what pins of the board I have hesitated. I am left to reverse engineer the wiring to find out.
