BlindVending Posted December 6, 2015 Share Posted December 6, 2015 I have a 167 that one selection just won't vend and says make a new selection over and over. I changed trays and still same thing and that tray works fine elsewhere. I ordered and finally received an entire new main harness that I believe hooks to the board and each tray. I've never installed one before. Is this easy? Do I need to remove every tray out of machine to do this. After I change it do I need to reconfigure anything in the settings of the machine. Currently my non working selection doesn't even show up in the settings Link to comment Share on other sites More sharing options...
Snickers Posted December 6, 2015 Share Posted December 6, 2015 I use mostly AP stuff but do have a couple cranes out there. I noticed that main harness upgrade available for purchase and thought to myself hmmmm I wonder how long I have until that needs done. I too will be listening for the answer to this seemingly pain in the az job. Link to comment Share on other sites More sharing options...
AZVendor Posted December 6, 2015 Share Posted December 6, 2015 There is no need to reprogram anything just from doing a new harness. It's not hard at all to install unless you have fat arms that don't allow easy access to tight quarters. Link to comment Share on other sites More sharing options...

Do I need to remove every tray or can I unattach current harness connections from trays and board while trays are still in? Link to comment Share on other sites More sharing options...
Walta Posted December 6, 2015 Share Posted December 6, 2015 I think is likely your diagnosis is wrong. Before you install the harness perform a factory clear on your board. Generally this symptom is. 1 Bad harness on shelf. 2 Bad motor on shelf. 3 Ram errors on the logic board 4 Bad solder connections on tray PCB 5 Bad driver PCB. 6 Bad main harness. Swapping the shelves can eliminate 1 & 2. If you must change the main harness it will be faster and easier to remove all the shelves. I posted the National vendors RAM Clear Procedures to the download section. I thought it was already there but I could not locate it. It will take some time for approval. http://vendiscuss.net/index.php?/files/file/108-national-vendors-ram-clear-procedures/ Walta Link to comment Share on other sites More sharing options...
sammer Posted December 7, 2015 Share Posted December 7, 2015 Its usually just a broken wire on that column. Easy to re attach that broken wire I have done it many times. Pull the tray out and look closely at the connector and you can usually spot the wire that's the problem. Link to comment Share on other sites More sharing options...
