check the coil on the coin door, when you power on the pin it should energize to accept coins otherwise the would go to the coin eject slot

Is the coin lockout coil connected and working?

Is the coin lockout linkage adjusted properly?

Is the replay unit already at it's maximum credit position? If so, then the coin lockout coil is supposed to shut off and thus block out any coins until you play off a couple of credits.

Are the coin mechs for the currency you are using? There could be a coin stuck (or other token shaped item) inside the mechanism?

Pictures would be wonderful. (At least I've no idea what you're describing.)

It is difficult to understand what precisely is occurring but there are not many possibilities given the lockout has been eliminated.
-are the coins getting through the entrance plate & coin chutes;
-have you tested the mechs out of the machine to verify they are getting through the correct passage (not the reject passage) & is the mech adjusted to take the coin denomination you are using;
-is the coin switch properly adjusted to activate when the coin hits & the coin is not being lodged on top of the switch;
-is the coin getting through to the coin box.
I use US quarters in my machines. At times I have had a devil of a time correctly adjusting coin mechs. So now if I have continuing difficulty I just cast the mech to one side & replace it. I purchased a number of mechs from TNT @ $6 ea & they have always worked perfectly. Also I will now only use Coin Mech brand mech-they seem to me to be more reliable & durable.

Good info Ken-I was not aware of that function.

Sounds like it doesn't have a coin mechanism in it.

Have you pulled the coin mechs and inspected them to insure they are not malfunctioning?

You can simulate a proper coin path through the coin mech holding it in your hands.

The coin mech itself may need service. There are pivoting parts that can get gummed up or obstructed.

A poster above asked if there is anything stuck internal to the coin mech. You did not answer that question.

A poster above asked what the coinage you are using is. And subsequently if the coin mech is rated for this coinage. You did not answer that question.

Take the coin mech(s) out of the coin door and see if you can get the coin to pass through to the proper path. If it is a quarter mech it should allow the quarter to drop straight through to the coin box and a nickel or dime, for example, to reject back to the coin return.

You infer that the coin slides are sized to keep the wrong coins from passing through. That comment has very limited applicability here. The actual coin slides, behind the coin entrance plates, do nothing more than getting the coins from the coin entrance plates to the coin mech. They do not size anything. The coin entrance plates will limit certain coins. And that is only if the proper plate has the proper sticker on it. A dime entrance plate will stop you from putting most any other coin in there than a dime. A quarter entrance plate will probably allow any coinage to pass through.

Pictures of your coin mechs, outside of the coin door, would be helpful here.

Pictures of the brackets that hold the coin mechs, with the coin mechs removed, would also be helpful.

I sell three styles of 25 cent mechs...the tan all plastic ones you can wash with soap and water, the metal style with the black plastic insert (in almost all new games these days) and the all metal coin mechs. They are all $6 each and all checked to make sure they work...email directly [email protected]
