Nino, I cleaned the pins on the MPU, put the MPU in Seawitch hooked up the J4 and all flashes worked. So i pull the wires out of the J4 connector on the Galaxy, cleaned them and re-bent them to give them more tension, put it all back together and it's working . So my guess it's the connector, so i'll probably replace pins and connector.

I'm hoping the problem is solved, who knows it may reset at any time then i'll follow your next instructions, which I have also checked out at pinrepair. I'm going back to play it now hopefully it's still working .

Still got G.I. to look at, but BIG thanks Nino, how much beer do I owe you now??

The fact it is fixed means that the connector and pins will need to be replaced in the future. "Resets" could be that connector, or C23 on the solenoid Driver board.

Enjoy the game !
