Question Black Hole problem with captured balls

Hello,

My Gottlieb Black Hole pinball has just started having a problem: when you lock a ball into the lower playfield capture hole and then end up finishing the game with that ball still down there the game doesn't eject the ball first, wait until it comes back to the main playfield to drain and then end the game completely. Instead, the game ends while leaving that ball down there. When you start the next game it then ejects that ball, the ball comes back to the main playfield and drains. However, when you do start that next game a ball is released like usual into play and once the lower playfield captured ball finally gets back up to the main playfield and drains the machine then releases that ball into play as well. You end up starting off a new game with two balls instead of one. Can anyone tell me what's going on with this? I'd appreciate it.

Thanks,

Rob

Sounds to me like you might be having a problem with one of the switches in the ball through. If the second switch is stuck, it might make the machine think there are to many balls. When the game ends, it may think there is already a two balls in the ball though and does not eject the captured ball until the next game starts. I hope this makes sense.

Question Tried cleaning the switches, nothing changed

Hello,

I cleaned the switches in the ball trough and the capture hole on the lower playfield, but the problem is still happening. I'm wondering if there's a circuit board problem somewhere. Any ideas?

Thanks,

Rob
