[Jukebox-list] AMI PUSHBUTTON QUESTION

[Dan Peshkin]

As you all probably know I am a novice to the world of jukeboxes.  I  
am in the process of getting an AMI F-120 going.  I received my  
manual but am still having a couple of problems.
The credit unit seems to be operational but I do not have a slug  
rejector/coin mechanism present in the machine.  It seems to work on  
free play , although the manual makes no mention of how to set up the  
machine for free play without coins.   I have an intermittent problem  
where the pushbuttons work for all 120 selections....but sometimes  
when I turn the machine on, only the first column (farthest left) of  
push buttons will work and the remaining will not.  I can not trace  
the cause.  I have a feeling that it has to do with the credit unit.   
I realize that the wiring to the  push buttons in in a series, but it  
makes no sense to me why one column of buttons works  and the rest  
will not.
