Hello--I recently acquired a 1979 Williams Gorgar with a Rottendog MPU 327 Board.
System was working but now won't enter 'attract' mode.
I reinstalled the MPU board and discovered that the LEDs don't reset after pressing SW1, Step f.
Can this problem be fixed?

Did you test out all the fuses in the backbox?

Thanks PinballManiac40. My son is home from college for the summer (EE Major). I plan on having him check all the fuses and connections with a digital multimeter.
Thanks HowardR, I'll post in SS Forum.
