I have just got finished re-setting all the selection unit on my Wurly 2800 - according to the manual.
Everything seems to be working fine now, but it appears that the jukebox is in "free play", which may not be a bad thing, but I want to know how to set it back to its original state.
I can put coins in and credits are added, as they should. I can press the credit button inside the selector unit and a credit is added, as it should. When I make a selection credits are subtracted, as they should. However, if I press a "letter" key with no credit, the jukebox operates as if a credit has been added - the "Select" light comes on and the buttons latch (this is only with the "letter" keys, not the "numbers").
I don't know if there is a "common" way that the 2800's are set to free play, but any ideas would be welcome.
