I have a Gottlieb Bronco someone is supposed to be picking up tomorrow and now all of the sudden the machine is skipping ball one and going straight to ball 2. Bascially, when the reset sequence finishes, it shows ball one and then when the ball hits the switch on the way to the shooter lane, it advances to ball 2. Any ideas on how to fix this? I don't currently have a schematic and the machine is being sold tomorrow. Someone help!!
