How do you replace the coin mech on an arcade cabinet? NEW PROBLEM!


#1

Hello Happy New Year.

I currently have arcade cabinets where the coin mechs don’t work. Is there a way I can fix them? In addition to hardware issues I also need help on the wiring. I need to find the wire on the jamma that activates the coin.

Please provide pictures as well if you can.

Thanks in advance.

NEW PROBLEM

So I manage to put in my coin mechs. Now I got another problem with my coin slot.

The coin microswitches (the microswitch that reads the coin) are locked for some reason. When I put it on test menu for my third strike and put it on the input menu, the coins are always pressing and they never release. It’s weird because the coin microswitches are doing the opposite. When I press the metal wire on the coin microswitch the button is “off” and when I don’t press anything the button stays “on”. This is happening with all my coin microswitches on all the arcade cabinets I worked on. When I connect a pushbutton microswitch to the coin wires it works normally. It’s off when I do nothing and it’s on when I press it. Again this happens with all the cabinets I worked on and I used different coin microswitches. Even a brand new one I bought today.

So does any one know how to fix this?

Thanks in advanced.

Here’s a link to the jamma pinout. Pins T and 16 should go to the microswitches on the coin mechs. As long as the coin is passing through the mech, it shouldn’t need replacement. They’re probably just need or adjustment or maybe the microswitches.

Here’s a video on adjusting a mech.

Thank you. I think I have to replace everything though. When I bought my cabinets the coin mech, the microswitches, and the coin entry button are all crap. I’m just better off replacing the whole thing.

I want to get the mech holder where you just have to lift up the thumb screw and put in the coin mech. As shown here:

Rear Entry Mech Holder System

Anyone ever used this?

Oh ya question anyone who is familiar with Happ products know the difference between:

Mech Holder W/ Coin Switch AND Mech Holder W/O Coin Switch

The Mech Holder W/O Coin Switch is more expensive then the one with the coin switch. No photos so I wouldn’t know. Again I’m look for this type of Coin Mech Holder:

Are they cherry microswitches like these? If so, make sure your wires are connected to the common terminal and the normally open terminal.
