I just picked up this working game and I am going through it making sure that everything works as it should. Going into the test menu, there are sections of the menu that don't work. For an example, in the solenoid test, I can start the testing process and I can scroll through the menu, but non of the solenoids fire. The same with the Flasher test. I can scroll through the menu, but no flashers are firing. There are other test that don't work also.
The mpu is a Rottendog, all the connectors look clean and in good shape.
I have never read about a problem like this before so I'm not sure where to start.
