    Need help in coin mechanism, I had set my machine to accept coins for single play. For the rest of my machines, it accepted it and credit 1 to the machine. It requires me to press the start button before I could start playing, else it will just keep on adding credits.

    I have one particular machine that when I insert the coin, it starts the game immediately without pressing the start button. Continues to add more coins to it, it add another player in the game and launch the ball into play, does it means my coin mechanism is faulty?

    Go into switch test and see what the switches are doing.

    But I had change the mechanism to electronic, so it does not trigger the switch at the bottom.

    You still need to go into switch test and see what is happening in the switch matrix when you drop a coin in. Can you swap the electronic coin mech with 1 of your other games and see what happens?

    I think he means that he has the coin switch wired into an electronic coin acceptor (or comparator) and is using an output from the validator to credit the game and not a normal coin switch.

    Probably something like this:

    Sounds like the shorting issue I had. I had bent a bulb socket to get access to something else, but I forgot to bend it back when I was done. It was touching another socket, and when I started the machine, it rapidly added credits and players.

    Check the areas you were working on, if any to see if you accidentally created a short between two different contacts.

    I tried to replaced the coin box with a new set, it seems that it is the setting on the machine. checked every wire and don't seems to be shorted. the wire should be connected to N.O switches right?
