I can't work this out
I have tried to work out which the 3 Jones plugs coin adjust is connected to the coin door. It is the 10C one
How do you swap to another one? Is it something to do with the free wire on the coin door? but if that was the case then there would be 2 spare wires not just 1.
If we have the 10c plug on 1 play per coin I can get 4 players (and the credit unit reel stays on white)
Change the plug to 2 plays per coin and put 2 coins in the credit wheel shows 4 but when we press the start button to get 4 players it gets to 3 but that's it.
On the coin unit I notice that when we get to the 3rd player the switch is open but if I close it and press the start I get the forth player activated.
Someone has said that the pin on the credit unit should be underneath the switch rather than on top of it. That's sort of makes sense but if it was in the wrong position how does it give me four players when the 10c plug is in the 1 game per coin position.
I can only assume that the contacts are sightly out of shape but still doesn't explain the forth player activating on 1 coin 1 game setting.
Tried to read the schematic but got lost after a while.
