A month ago i bougth my first used vending machine (dixie narco series 90) and i tested for a week at home and it work fine the coin and bill mechanisms.
After moving it to my machine shop and powering it up the exact change ligth turned on and i haven't. Been able to fix it i took apart the coin mech to clean it but the ligth still on it vends correctly but only with coins the bill validator seems to work it takes the bill but it gives it back the coin mech its a single price trc6800h and the bill its a mag50g
I almost forgot i tried cleaning the coin mech a couple of times with no succes and loading with plenty of coins and i noticed that a led behind casset with the words blocker its on.
The bill validator has an led flashing once every ten secs but the bill box its empty
