Snickers Posted April 21, 2018 Share Posted April 21, 2018 Got a couple National 157's off location and decided to upgrade them with the hard wired tray board kits. All is well with 1 of them but I am running into Error D on the other. All connections are checked and seated correctly. I can test vend D4,D6,D8 but when I do it turns the D0 spirals just a little. D0 and D2 will not test vend. I know there was not a problem before I put this kit on also another strange thing the Mars bill acceptor is getting #1 flash error-coins only. There was nothing wrong before. I really like these machines but working on them can be aggravating. I will fool with it again tomorrow but don't know what to do at this point besides swap known good tray board and bill acceptor and see what happens.
