Wonder if anyone else has had this particular issue:
I own a premium and a pro (two different locations).
On my pro, the left ramp shot (T Rex ramp) does not register if the ball enters the ramp at a high velocity.
The opto switch registers 100% when tested by rolling a ball past it. But if a ball is sent past it rapidly it does not always register.
I have cleaned the switch. Unplugged and repluged all the connections from the switch to the board. I have mechanically altered the angle of the transmitter switch slightly up and down and none of these maneuvers have changed the results. Again, it only fails to register when the ball passes at a high velocity.
I took the two plastic spacers off the back of the ramp that support the roof over the ramp, and lowered that roof all the way down to prevent the ball obtaining any air when it makes the circle behind the playfield. That helped about 50%. Then, I turn down the power on the right flipper, and now the switch registers about 90% of the time. Again, the only time it doesn’t register is a really hard shot from the right flipper that travels rapidly through the ramp.
Never had this problem on my premium model.
Any suggestions?
