I only unsoldered 2 wires which i marked so that they would go back the same way. However somebody else could have done it to setup the free play.
I have attached a photo of the switch position when there are 0 credits, and as you guessed these 2 contacts are not open. When I manually try to open the contacts it is all a bit too stiff and doesn't want to. Are the switch blades(is this the correct name) in their correct positions?
