Hi guys, I don't post too often and am a newbie hands on guy so I like to tinker but need to learn more. I just bought a Six Million Dollar Man game and had it shipped to my home. Upon turning it on, everything seems to work except I cannot make the "Start" button activate. I am not sure what to check first. As I power the game up, everything seems to light up and the solenoids fire and things reset. Then I push the start (credit) button and nothing happens. The flippers don't activate. Could it be a tilt reset or something? Any ideas please?

Another quick question: Inside the game is an outlet (see picture attached). Does anyone know what this is for? Do I plug something into it?

Okay, adding more than one quarter worked! I thought it just needed one coin but it needs more. Now I played my first game on it! Yay! Thanks a bunch for helping me.
