Update- I by passed the coin mech ans set the machine to free vend but no vending UNLESS I go into the service menu and run the test vend and then both columns vend. If I try to vend with the selector switch the display freezes on 0 and no vend.
That's the problem...wurlitzer w64... No service or parts available...talked to manufacturer so was hoping I could get something generic that covers the vending process from start to finish including all switches, coin validator so I can troubleshoot. I have the manual but it's not helpful on troubleshooting
