nrod7 Posted January 31, 2017 Share Posted January 31, 2017 The machine has a 24 volt mars dollar validator ( 2500 series) and a Coinco mdb coin mech. Vend price is .75. If, I insert change the machine will dispense the product. with no issues. If, I insert 1 dollar bill the machine will dispense the product, but it will not drop the .25 cents in change. Also, the LED will reflect the .25 cents credit. if I push the coin return, then it will drop the change/credit. I have already swapped out the DBV, the coin mech, the harness and checked the three fuses on the mother board. I am stumped. nrod7 Link to comment Share on other sites More sharing options...
Southeast Treats Posted January 31, 2017 Share Posted January 31, 2017 Sounds like the programming is set to multi-vend, it allows the credit to be held for a second purchase unless the customer ends the transaction by pushing the coin return. Customers never understand it. Check your programming menu and set to single vend. Link to comment Share on other sites More sharing options...
