Wiring Coin Controls coin door counter **wiring diagram added**
mountain:
Spikes are basically the release of stored magnetic energy from a coil caused by fluctuating current levels. These can generally create problems with sensitive electronics, noise in audio circuits (pops, static), and noise in video circuits.
In the Aviation industry, all relays are to be equiped with a diode across the coil.

If/when you get your meter working will you post some info on the process please? I have a Coin Controls door and am going to be wireing it soon and would like to have the counter work. I realize that yours might be a different counter but I would still get the basics and the only variation would probably be the voltage.
Thanks,
Brian

there is real good chance your meter will not work after taking it apart.
you would be better off getting a new one and matching it to the most handy dc volts you have

Since the OP seems to have an idea of the basics of how the counter is meant to function, but the title of the thread is so perfect... I will ask. How does the coin counter get a signal to add one to the display? I understand basic electronics/wiring so pretend I know what the terms mean I just haven't hooked up a counter before and don't know the principles behind it.

There is a coil inside the counter. When the proper voltage is applied across the coil it magnetically pulls a lever (much like a relay) which in turn triggers the counter mechanically. So on a 12v counter you would have 12v sitting on the high side of the coil. When a coin is inserted it triggers the switch which will send a ground pulse to the counter.

No worries, it is a very simple design. The frustrating part is getting all of the digits lined up at the sime time since they are very light action and move with the slightest vibration. Matching the voltage will be easy, I just need to start off with the lowest possible used voltage and work up. (thanks again Ken Layton for the voltage info)

I will post my progress here as soon as I get back into it
