Hello All
I am working on a Sys 80 A game Rack 'Em Up. It was working fine until my friend replaced a drop target. Now it lits up and shows the displays. You can add credit and when you push the start button the game goes to player 1 and the game resets and appears ready to play. It will not shoot the ball into the shooter lane and if you hit any of the bumpers or rollover switches, the game does not register anything. If I put the game into test mode, all the tests including the solenoid test are perfect. I have checked the coin door slam switch and it works if I trigger it. I can hold in the game over relay and the pop bumpers and flippers will work. I have not done the slam switch fix on the cpu as I assumed the slam switch was working correctly. Any ideas on where to look now?
Thanks
Mike

Yes I did. It is workking correctly.
Thanks

Thanks Chris. I did but I will re-check.I did have one of the rollover that did not register when depressed. Assumed it was just one bad switch.
