Hey Randy,
sorry to hear about that issue, I never played the machine much and wasn't aware of the cycling thing.
One thing to also look into is to be sure that all switches in the path to the solenoid make good clean contact.
I had issues with the bonus stepper on my Card Whiz and after messing around with the relay to no avail, I realized it was a dirty switch that wasn't making good contact that didn't give enough power to the solenoid to do its thing.
