I am going to try my hand at a home nickle arcade. It sounded easy. Get some cheap machines and swap out their old coin slots for new ones that can be programmed to take nickles. I planned to just swap wires. I should have known that nothing ls ever that easy. My first machine plays great (free play) but has a broken dollar bill acceptor. I have learned that it is a 115vac device, and my new coin slots are all 12vdc. I am powering the coin acceptor with a computer power supply to get my 12vdc. I cannot figure out how to pulse the Normally Open (NO) relay that adds credits to the machine. The bill acceptor uses pins 4, 6, 7, and 8 (diagram below) and the yellow portion of the image is the device I am trying to replace it with. (You can ignore the 24vac reference on pin 6 as that is for a different model and I neglected to remove it from my final image.) I know it isn't much to go on as far as documentation goes... Is there something simple I can do to trigger the relay for credits using this 12vdc coin slot?? Thank you in advance for any direction or informational links to study.
