Ok, I plugged the big relay and the coin mech into a friends DN180 and it worked properly. I also can manually trigger the vend motors by pressing the microswitches on them. Any more ideas?
Thanks for the help. The current price set on the machine is 50 cents. When I put in any more than that it returns change. When I put in 50 cents the "Use Correct Change" light comes on for a second and then turns off. I did not notice the relay clicking. I unplugged the relay and plugged it back in and its the same story. By the way, in case its needed the coin mech is a Coinco Dex 9300.
