Hi everyone... Figured now with owning 2 pinballs, I may need to get involved in here more and learn some on basic repairs.
I have a 1971 Gottlieb 4 Square. Was working when picked up. Now, after score reels reset after new game start, I am able to launch ball but when the ball hits anything to register a score, it appears that the score motor engages and does not disengage, buzzing very loudly. I am hoping this would be as simple as a cleaning in the general area, but otherwise, without a schematic or manual for repair, I don't have much more on what it could be and the required fix. And I would rather not pay $200 for a house call if it is a minor issue.
Any assistance would be greatly appreciated.
