Quoted from pinball4ever:I'm not sure if Gottlieb has this type of setting, but I once fixed a Bally machine that had this exact same problem. It turned out to be a setting "Max Credits" that was set a zero. So, you could never add a credit to the game.
I never understood why that was even an option, but changing it to "20" fixed the problem immediately. The owner of the game could never get it to work because of this (seemingly) minor issue.
If there is a setting like this, it would be accessed from the coin door controls.
It's not an option on Gottliebs. The max credits are controlled by dip switches--the minimum is 8 and the max is 25.
