I’m having a similar problem. Just got the machine, and it had no power to the shot clock or defender. Reseated everything, pulled all the fuses, no change. Finally bought and installed a new rottendog driver board, and still
The same problem. (Incendentally, I guess i’ve got a working WPC 95 board for sale now). I’m not sure where else I should be looking. PinJer, did you ever fix this? Any other advice? I’m stumped.
