Gottlieb Quick Draw ball advance issue: tech help?

I have a Gottlieb Quick Draw pinball. The problem I’m having is when the ball is over it does not always cycle to the next ball. It keeps going. Can anyone help

Howdy! Not sure if you’re going to get repair advice on this platform, but Pinside will likely be more fruitful in terms of connecting with others on repair issues. Here’s a link to all forum topics on Quick Draw:

I don’t see an all-encompassing “owners thread”, but if you drop a new topic in the “EM-Tech” category you’re likely to get a reply:

The EM Pinball group on Facebook is really helpful for EM tech questions. Just don’t ask for pdf of a Gottlieb manual.
