A Simple Issue Kept This Gottlieb 1957 Royal Flush Pinball From Working…

Follow along as I spend some time attempting to fix this almost 70 year old pinball machine. Finally arriving at the smoking gun. Hope this helps someone else with one of these machines in the future!

Symptom: When pressing new game button, game would start resetting and get stuck. After a second button click the game would fully reset.

Solution: one of the switches on the ball release solenoid was not working properly, due to a short in the circuit.
