[Jukebox-list] AMI PUSHBUTTON QUESTION

[Wesley Dean]

    Dan, the pushbutton switches are fed with a credit 'hot' to the first 
button in what is called a 'daisy chain' circuit that continues trough all 
pushbutton switches. This is a normally closed circuit. If one of these 
switches lose continuity, all switches down the chain will not work. This 
path may be different on various jukes. All jukes use this circuit as an 
anti-cheat feature to prevent anyone from pushing two switches at one time 
to get two selections for one coin. Each bank is connected to another one 
with a jumper wire. The trouble may be here or either someone has pushed a 
button back in that has jumped out. If this has been done without backing at 
the rear of the shaft, the normally closed may be distorted and lose 
continuity. Wes
