Knockout
Bally, 1975I’ve been trying to get my Bally Knockout project. I’m still trying to get it to startup completely. It was getting to the score reel reset, now I can get it to the ball in play step, however if I have a ball in the out hole it shuts off at that point, if not it shows ball in play 1 and stops there. Any thoughts
If power to the machine is turning off during the reset process, there might be a coil or solenoid that is burnt out or shorted out. Check the outhole kicker solenoid to see if it's operating properly. You can also check the ohms rating of the solenoid with a multimeter.
After more troubleshooting I noticed that the outhole switch was sparking during the reset process and the kicker itself barely fires before shutting off. I had a replacement for the one coil but not for the kicker itself, but that didn’t solve problem so I guess I need to order a replacement for the other one. If I test it with a multimeter, what should I look for.
Also does anyone know what the first switch assembly is for, it is not labeled?

This is the best I can do without running to kinkos

Not sure what the problem is. Here are some pictures that might help someone solve the problem
