Hi, I have an Addams Family Pinball. The vault doesn't open in a stable way. When it has to open it sometimes opens immediately (perfect opening). Other times it has to try 2 or 3 times (opens & closes). And when it sometimes stopes opening, it is not perfectly open (halfway). What could cause this? I check the cables and cleaned all contact points. Could it be the IC (18)? or what other suggestion do you have? Thanks, Maurice

Hi Chad,

Thanks for your reply and sugegstions. In test mode it does work fine although the 'open' switch stays slightly longer active than the 'closed' switch. Although, when I run the first test, the switch were not working at all, so I did it a second time. Then the switches worked (with above comment). Also testing it afterwards in real play mode, the bookcase opened perfectly. It is not a stable process.

Thanks for advise.
