Thanks for your response. I ran the switch test and "67" came up in the credit window. So in the manual I was able to figure out it was the ball kicker switch. It was bent closed... Something so simple has been driving me crazy for months. I thought it had to be one of the drop targets that was causing the issue...
However, after playing it for awhile I determined another problem. When the ball was in the basement the ball got stuck in the "Special". Just kept adding points, wouldn't kick the ball out. I ran the solenoid 17 test and nothing turned on for 2 and 6. I'm guessing that the solenoid is either 2 or 6, and there must be another solenoid not working as well. Could this be as simple as a fuse?
Thanks again for all of your help, as you can tell I am a novice at this hobby but I want to learn.
