AngryChris Posted January 1, 2017 Share Posted January 1, 2017 I'm attempting to tackle this old gremlin again. I have a vendo 720 that vends multiple columns simultaneously. Currently, I saw most motors work fine. However, when column 8 ran, 3 ran too. When 10 ran, 5 ran as well. I can only test vend these selections if the sold out paddles are depressed in the column I am testing. I have already replaced the harnesses from the board to the motors with no success. Although most of the machine functions properly, these multiple vends make the machine an obvious problem. At this point, I'm not sure if the previously replaced board shorted out on me (broken standoffs allowed metal contact) or if bad motors could cause this or something else. I'm open to all suggestions and I will be replacing the board. Link to comment Share on other sites More sharing options...
CajunCandy Posted January 1, 2017 Share Posted January 1, 2017 I've had that problem before and after I replaced the board it would vend properly. Good luck AngryChris. cajun Link to comment Share on other sites More sharing options...
AngryChris Posted January 1, 2017 Author Share Posted January 1, 2017 Thanks. I learned years ago (from this) that control board standoffs are there for a reason lol. Link to comment Share on other sites More sharing options...
