Coin Door Problems

[Tokey]

I've having some problems with credits registering and my coin door.  If I open up notepad, every single time I drop a quarter in it works perfectly (registers as "C" and "W" for coin 1 and 2).

In some games like 1944 it works perfectly.  In some games like Street Fighter Alpha 3 nothing happens when I put credits in.  And some games like Puzzle Bobble when I put a coin it the screen says "Coin Error".

Any guesses?  I was thinking maybe I had something hooked up wrong and was going to try rewiring stuff when I get home, but I don't think that's the issue since it works perfectly in notepad.

is exactly what's happening, I must have wired them wrong.

[Tokey]

So how do I know which one is NC and which one is NO?

I just have them wired like this:

______
           |____
           |
           |____ (wired)
_____.|
       |
       |____ (wired)


Does it matter which wire goes to which (polarity)?  Or do I just need to change it to be the top and bottom instead of the bottom two?

look at the picture towards the bottom of the buttons...this is generally the way microswitches are set up:

So I need to make it the top 2 instead of the bottom 2 according to that?  I'll try that as soon as I get home.

From what I see, your ASCII art implies you have it currently wired in the same manner as indicated in the picture in the link above.

Are these Happs buttons? Even if not the switches themselves should be marked.

In all likelihood it is the first and third connections that should be made, not the top 2. The connection on the very bottom is most likely ground.

An easy test for newbies who don't have a logic / continuity thingy, is get a small flashlight. Take out the light bulb and one battery. Get two wires. Now connect the wires to the battery and bulb. Lights up right?

Now get a third wire and wire it all up to the coin switch (or any other switch you want to test). Your circuit should be a "circle". Hit the switch, and it should light the bulb. If the bulb is lit already and hitting the switch turns it off, then you know you're using the wrong tab on the switch (the NC which means "Normally Closed").

Added 5 minutes later:
Actually, if you're a real dunce for something simple as wiring up a lightbulb, then you could leave the Flashlight intact, but rip out the Flashlight's on/off button.

You'll find the button has 2 wires. The switch basically connects them together, causing electricity to flow, making the bulb light up. Rip out that switch, and instead attach two long wires. Now you can hook up these wires to any switch you want to test, as explained above...

For those still wiring up cabinets without a multimeter, Home Depot has them for under $20.  Wal-Mart usually has them too, although I can't find one on their site right now.  I can't imagine building a cabinet without a multimeter or at least a continuity tester.

These are the original coin mechs from my 25 year old cab, so I don't know if they are happs or not.  I actually do have a multimeter, I just thought it was wired correctly and didn't even think of using it.

I want to get the tokens but I don't know if I can even convert the mechs to take them.  Guess i'll order 100 and find out.

I'll try to get it modified then, if I can't I'll be buying 2 mechs from you I think.

What is the deal with Harbor Freight?

[Dougmeister]

Tokey, did the mechs work for you once you switched the connections?  I'm having similar problems...

[Tokey]

Yep I switched the connections to top and bottom and everything works perfectly now.
