OK.. so I took on the challenge of getting my Haunted House pinball back up and working. After replacing several boards and seemingly making progress, I got stuck when one up kicker was not functioning, plus a few other items seemed a bit buggy. Called the local pinball expert to get some eyes on it. They thought my old MPU board should be replaced, especially since I had already replaced the power and driver boards. I should note that when doing tests with the old board cycling through 16-20, the tests would work. Solenoids would fire, etc. So you see where I am going. I put in the new MPU board, made sure the switches matched my old board and double checked the game setting switches to make sure it was set for Haunted House. Rewired the A1-J4 to A3-J1 connector and installed. Old board had A1-J4 connection directly soldered. So the game powers up but when doing test 16 (lights) and 17 (solenoids) nothing seems to be happening.
Any direction would be helpful. Attached picture of OLD board before removal and New board after install.
Before I tear out the edge connector I made and rewire it, I thought I would seek guidance from fellow Pinsiders..
