[Jukebox-list] Wurly 1250 selection problem

Hi all, My Wurlitzer 1250 was working perfectly and then refused selections when any of the twenty-four selection buttons are depressed.  I checked the coin grinder and it runs, accepts coins and 24v goes to the make selection light so I know that transformer is good.  I've been looking at the schematic and at a loss of where to begin.  I was going to pull the junction box and and check the 24v transformer but it is supplying power to the selection light.  Any thoughts?
