Wiring Coin Controls coin door counter **wiring diagram added**
mountain:
I have a Coin Controls coin door and want to wire the coin counter. I was able to reset it to 0 by taking it apart (not recomended :banghead: ). I know that I need to wire the ground pulse from the mech switches to the counter and diode isolate everything. What I am unsure of is whether the counter uses 5v or 12v. There are not any markings on it to indicate. I know they come in different flavors. Does anyone happen to know what type Coin Controls used in there coin doors?
Ken Layton:
Coin Controls, as with other coin door manufacturers, provided coin counting meters in several voltages as required by the original game cabinet manufacturer. All coin door manufacturers use coin counting meters from several different meter manufacturers in order to meet production quotas so you could have 1 of 4 different meter brands in there.
As with all coin counting meters, the meter manufacturer's name, model number, and voltage are silkscreened or engraved into the meter case (may require dismounting the meter to look). Typical voltages of amusement applications are 4.5 VDC, 6VDC, 10VDC (Atari specific), and 12VDC.
Some meters have a built-in blocking/spike suppression diode and will usually be printed on the meter case "with diode" or it will have color coded red and black wires. If the above conditions are not present on your particular meter then assume it does not have this diode and a seperate one will need to be installed external to the meter to protect your circuitry.

Thanks Ken,
I will look at it again. The spike suppression diode goes across the coil, correct?
Ken Layton:
Yes, with the cathode side of a 1N4004 (or higher rated) diode going to the power source positive (+) side. Power source voltage must match the meter specs (i.e. 12 volt meter connects to 12 volts).

I don't think I've ever fully understood what that phrase means exactly.
