Haunted House Sound, Solendoids and Lights don't work.
I fixed my MPU lockup problem. I had a bad 5101 ram chip. Now the game doens't play. I have done the ground mods, but I haven't changed the harness between the mpu and the driver board. Right now I don't have sound, solenoids, or playfield lighting. The sound only plays the attract sounds and the sound board stays in attract mode after starting a game. The only solenoids that work are the outhole kicker and the cabinet knocker. I thought for sure that it was going to be U6 (6532 riot chip). I changed that and there was no change. I'm studying the schematics now to try and see what chip could affect all three. Any help would be greatly appreciaated.
