Here's the issue...
When the ball goes around the magic bus loop with speed and "magic bus" is lit, sometimes the switch will trip and then de-activate, causing the ball to just be sent back to the right flipper. The momentum of the ball off the up-post will cause the ball to trip the switch, then the ball backs up the ramp a bit, causing the switch to de-activate. There is normally a grace period, but sometimes there is not.
And when there is not, it is extremely annoying. When this lack of a grace period happens during "Mamushka" or any mode for that matter, sometime the up-post will just stay up and lock the ball, and the only way to get it down is to shut off the machine.
I duplicate this by manually tripping the switches, then dropping the bus switch. The machine just assumes there was no ball. But I can't duplicate the lack of grace period. This only happens on a hard shot, and it only takes the blink of an eye for it to occur.
I just installed a brand new switch and new diode hoping to fix this, and I am right back where I started. And yes, they were soldered in correctly.
Has this happened to anyone else? And what have you done to fix it? I have already ruined one switch trying to solve this. Bending the actuator this way and that way. I ended up ruining the plastic nubs that hold the actuator.
