Trying to chase down this Paragon issue.
Bought game nonworking. No CPU, bought a rebuilt one.No GI, pretty hacked transformer board.
Replaced the board with a new one. Also repinned the connectors to that board. Worked for very short time (a few minutes).
Long story short, F4 toasted. Popped a new one in, same thing. confirmed, no 43 volts. MPU
I've done the following:
Unplugged the playfield just to rule out anything there. No change.
Unplugged the lamp driver board, displays, sound board (again, just to rule out anything). No change.
One odd thing is that when I repinned the connectors, I was missing a wire, but not sure if I'm supposed to have it or not. A2/J3 Pin 13 is supposed to be white/yellow, and I have no wire into it. Supposed to go to solenoid bus.
So I'm a little stumped. According to the schematic as I read them, 43v is the solenoid bus.
I know I'm missing something silly, but I'm overtired and slightly medicated, so I can't think this through on my own. Anyone care to help?
