I have a 1977 "pinball" by Stern. I've replaced the MPU and Solenoid Driver with new Alltek parts. After doing that most of the game has come to life however I have one drop target bank that will not reset. Being fairly new to repair I'm not sure where to start with a problem like this.
What should I look for? Visually things look ok to me.
Here's can see the left drops not resetting like that right bank

Well, this was an easy one! I cleaned those contacts on the bottom of the targets and—BOOM—works just like new!
Thanks, pinkid and
