The left and right switches in the back need to be changed. I ordered a couple but the ones i got
don't have a diode on them like the ones that are in the game already. Do I need a new diode or can I use the old one or do I need one at all? thanks fellas

I found some I had left over and just replaced them. Forgot about the direction part until after i soldered the first one in. Got em both working and the game is back to fully functional except for the top left plastic in the backbox. The ball gets stuck because it isn't there. Gonna rig something till I can find one. This machine was very dirty and I can't believe how much smooth and faster it plays now that it has a couple coats of wax. People say it's a bad game but it's the one that has taught me how to catch balls and it holds a place in my heart. Thanks for the quick replies. Really appreciate it.
