My machine wont take coins

That coin looks small in there. Is it a quarter? On the front of the comparator is a small screw with + and -, turn that screw to the far - to reduce sensitivity. I'm not 100% sure here but I think the optic path  has different inserts for different size coins. Another thing you can try is to remove the comparator then you will see the coin rake with a solenoid you can wire it open so all coins go to the optics.

FYI, he fixed it about 10 posts ago.
 
And I wish I would have thought of those things.

WOW must have been a glitch. When I posted all I saw was his picture. That was a lot of posts between. Glad he got the rake problem solved.

for future reference: if the pseudo coin button works (puts the max allowable credits on the machine) and the machine works as advertised, then 99% of the time its something wrong with the CC-16. there are a few things that would cause the CC-16 not to work. A bad connector( usually a broken of frayed wire, black or yellow ones , those are the power)  if the unit is getting power it will do what it is supposed to do, one thing and only one thing, compare a metal object to the sample in the unit. It does this by establishing a electronic signature  for the sample coin, when you insert another metal object into the comparator it compares  the two signatures, if they match then a signal is sent to the solenoid to pull in the rake and allow the coin to pass. If they don't match then  it is  rejected and sent to the coin tray. Because of counterfeiting, some casino's used their own tokens, their tokens were made to their specifications, and when they put that token in the CC-16 they could adjust that sensitivity setting to where it would accept only their token and reject all others. That was the purpose of that  setting, for home use, we recommend that the setting is max. CCW, this allows little or no differentiating, so 99% of the coins inserted will compare to the sample and be accepted.

Most S+ machines that people have today have a bill acceptor, which means they have a belly door. If people are curious and they want to see what is happening when the door is closed and they don't want to fool with the door optics, there is a way you can observe the CC-16 assembly in action. remove the cc-16 from its four plastic holders, remove the two screws that attach the bracket to the coin head assembly, unplug the assembly, remove the assembly  from the machine, open the belly door, put the cc-16 back into the bracket, plug the assembly into the harness, close the door, turn on the power to the machine, now, holding the assembly in one hand, you can see the LED come on, and you can insert coins into the cc-16 and watch them pass through the cc-16 into the optics and into the  palm of your hand. Of course, there are implied logical common sense to complete this action, I can not list every step to accomplish this, but if you are faced  with a coin in problem this is one way to get a hands on feel for the problem. E.g. the ten pin connector that plugs into the optic board, an intermittent wire connection on that plug could cause a code 21, so with the assembly out, you could wiggle that connector and see if you can duplicate the problem, etc. etc,

Hope this helps
