This is going to be a bit lengthy so bear with me.
I was called to a customer home for his juke not working after his home sustained a lightning hit. I was told that a TV, Pool pump, Dishwasher all damaged. His juke was not powered on during the strike but shortly after he noticed it would not accept a selection.
In the display it would show first digit then when pushing 2nd digit button the display would go blank.
In service mode mech magazine would not rotate but you could hear a click from the sprag solenoid.
I replaced the mech controller board and no change. Next the Central computer still no change. I pulled his mech, Central computer, and power supply brought them back to my shop and tested each component one at a time in my shop machine and ALL his components work fine.
He brought the complete machine to my shop for further troubleshooting. I reinstalled all his original components and now in idle state the magazine motor is constantly receiving power pulses. If I manually operate the sprag assembly the magazine starts to rotate in a slow jerky motion. I even replaced the service switch but I am now at a loss what is causing this issue. Again all his original components operate properly in my shop machine.
I would welcome any input on what could be causing this.
Regards,
Rick
