once a flavor is selected, the appropriate column motor starts to rotate the augers & there is a switch on the bottom of the augers triggered by another micro-switch that will signal ( break the self-latch) the vending relay & terminate the vending cycle, it will also send a signal (125volts) back to the coinmech on pin #7 to tell it it can accept more coins now ( the coinmech was locked out during the vending cycle) if you have to hold the "free-play button in all the time while you select a flavor, then the vending relay isn't being set. I am the originator of the diagram you see on the pinned subject " the free play switch once more" it is a general diagram intended originally for bottle stack type machines, it usually works fine on multi-button machines, but some machines are wired a little differently. did the machine vend properly with the coinmech installed?

I followed the above diagram. Basically if I hold the momentary switch down and the augers spin after soda selection. Once I release the switch the augers stop. I have a choicevend CVB-181 machine. I can't seem to get it to work properly. The coin mech did not work when I bought the machine.
