Title: Bally Progressive " 77 " Code keeps coming back ! Anyone know why ?
Post by: gordy on October 01, 2013, 01:02:37 PM
Got a Bally 6000 with the big wheel and arrow up top. At it's other location there had been a power outage and this machine lost it's progressive capability after working perfectly before. A guy programmed  the progressive for me.  Turned it on and the arrow did not customarily rotate during the initializing. The machine played, and the prog. increased as credits were played, until the bonus was hit. When the bonus button was pressed the arrow did not move at all.  Then a  77  appeared.  I went to page 14 on prog. problems on NLG and then did a RAM clear and set the options.  Checked to make sure on SW#1 that 456 were correctly set.  Played the machine.  Same result. Checked plugs and wires.   Any solutions ?   Gordy   SOLVED Loose plug on the floor of the machine.
