Good morning all. Well, I installed the brick back into the console. I left the jumpers in J2 to bypass the interlock switch. I still have the same power to J5, but when I put the coins in the game, no lights, no sound, no life. I need to continue to trace out the circuit. As soon as Mike uploads more schematic pics, I'll keep working upstream. Maybe next I'll check out the voltages at the coin receptor. Not sure if that's the next logical check point. I wonder if there are any other fuses that I'm not aware of, other than the ones on the PS. I feel that I should be seeing or hearing something. Again, thanks for all you help!
