I have a Gottlieb Card Whiz that if not for the "ball gate" issue, the pin operates 100%.
Trough,runway and EX switches are cleaned and gaped properly.
Resistance at the coil reads 15.
When the ball rolls over the lane guide on the right hand side, the gate opens as it should
but then immediately closes so the coil is not staying energized.
Any help would be greatly appreciated.
