Ok, I just picked up the ROTJ cockpit and am having an issue with the power.
I was looking at the schematics and noticed that the power brick in the game currently, did not have F2 populated at all. No wires, no fuse. The schems show all 5 of F connections being used.
I swapped in a power brick from a known working game (centipede) and powered up. Nothing but blank raster. Lights up the cab lights, coin door, powers the monitor, etc.
Then, I noticed that the J6 plug was not plugged into the ARII pcb. I plugged it in (with the new power brick) and got a LOUD buzz through the speakers.
For the first (even though brief) time, the pcb showed power by the red light. I left it on for about 3 seconds, blew the fuse on the brick at F4.
Any ideas what is causing this?
