Thanks for the procedures

OK, before take mesure, I need to know which Xevious PCB I have
![Huh ???](http://newforum.arcadecontrols.com/Smileys/default/huh.gif)
There's nothing written on the PCB
![Shocked :o](http://newforum.arcadecontrols.com/Smileys/default/shocked.gif)
Can you help me to identify it ?
Here's the CPU pcb :

and the VIDEO pcb :

...there's no ATARI or NAMCO indication
![Huh ???](http://newforum.arcadecontrols.com/Smileys/default/huh.gif)
I've found on a website this :
"Xevious" (Atari, 1983)

but according my harness :

...it doesn't seems to fit the documentation... So I presume it's a Namco pcb... and I'm not able to find pinout description for the Namco pcb
![Embarrassed :-[](http://newforum.arcadecontrols.com/Smileys/default/embarrassed.gif)
OK, so I decide to check what I can... and I try to found the +5V
The power come in wires from AR2 in two places :
- On this connector :

- and on the main harness.
A strange thing... When I remove this cable...

... and I power on the game, there is a bad smell and some smoke seems to come from the AR2
![Angry >:(](http://newforum.arcadecontrols.com/Smileys/default/angry.gif)
What do you suggest ?
I would like to know which PCB version I have, in order to get the right pin out, and check at least the voltage
